Installation

• Release the scanner carriage

• Connect your scanner and computer

• Check the SCSI ID

Releasing the carriage Your scanner has a locking screw at the bottom to protect the

scanner carriage mechanism during shipping. Before you can operate the scanner, you need to disengage the locking screw.

To unlock the scanner:

1 With the scanner turned off, turn the scanner on its side to see

the locking screw at the bottom.

2 Using a screwdriver, turn the locking screw counterclockwise

to unlock it. When unlocked successfully, the screw will push out a little, becoming nearly even with the bottom of the scanner.

You can check the lock’s status by pushing on the screw cap. If the screw springs back, the scanner is ready for scanning.

Cabling The following scenarios are provided to show how to connect

your scanner to the computer and the other components you may have in your system.

1-6

Note:

Polaroid scanners are not internally terminated. Always use short cables 2-3 feet long for connection; longer cables can cause SCSI-related problems.

Case 1

Connecting the scanner to a Macintosh. There are no other SCSI peripherals.

Case 2

Connecting the scanner to a non-Polaroid SCSI peripheral (like a CD-ROM drive, tape drive, optical disk drive). The non-Polaroid SCSI peripheral has two 50-pin Centronics ports. In this case, you will need a SCSI peripheral cable (see Note on the next page).

Case 3

Similar to case 2, but the non-Polaroid SCSI peripheral has a 50-pin port and a 25-pin port. In this case, you can use the cable provided with the scanner, but you will need a terminator.

Note:

SCSI peripheral cables and terminators are not included with your Polaroid scanner but can be obtained from any computer reseller. For your SCSI peripheral cable, use cables no longer than 4 feet; longer cables may cause SCSI-related problems. The use of terminators is explained more fully in the next section,

Using terminators.

Using terminators Depending on your system, you may need to use a cable termi-

nator on your installation. A terminator is a piece of electrical equipment installed at the end of a SCSI chain linking your computer with a SCSI device. The terminator ensures that the electrical impulses going through the path are properly routed and absorbed.

When to use a terminator

Polaroid scanners are not internally terminated, and Polaroid does not provide a terminator in its scanner package. You may or may not need a terminator, but because of varying SCSI standards, there is no way to predict with absolute certainty whether or not you need one.

If you get odd symptoms after hooking up your Macintosh and scanner, or if your Mac refuses to boot up properly after you installed the scanner, this may indicate that you need a termina-

1-8

scanner

terminator

tor (or a shorter cable). In this case, obtain a terminator from a computer reseller, and use it as part of your installation.

On the other hand, if you are hooking up your Macintosh to a daisy chain with two or more SCSI devices (such as a scanner and a CD-ROM drive), you will definitely need a terminator, and the terminator should then be on the last SCSI device on your daisy chain. There should never be more than two terminators on your system (one is usually inside the hard disk of your computer, and one should be outside on the last SCSI device).

To install a terminator if you’re hooking up a Macintosh, a scanner, and a SCSI peripheral, refer to the diagram in Case 2 on page 1-7.

The SCSI ID A SCSI ID is a number assigned to each SCSI device in your

daisy chain to differentiate the devices from one another.

The SCSI ID for Polaroid scanners is set at default to 6. You won’t need to change the SCSI ID on your scanner unless another SCSI device on your system (such as a tape drive or CD-ROM drive) is using the same number.

To set the SCSI ID number:

1 Locate the SCSI ID selector, which is on the back panel.

2 To change the SCSI ID, press the push-button selector. See

Notes on SCSI numbers for numbers that can be used.

Hardware installation 1-9

SCSI ID selector

Notes on SCSI ID numbers

• Each SCSI device must have a unique SCSI ID number.

• Valid SCSI ID numbers are 0 to 6. Do not use SCSI ID #7,

which is used to carry a self-test for the scanner and make the carriage move back and forth. SCSI ID #8 and #9 are also not used.

• The Macintosh internal hard disk usually occupies SCSI ID

#0 or #1, but it can be set to any number.

SCSI conflicts

Conflicts between your scanner and other SCSI hardware devices in your system can happen, owing to the varying SCSI standards that are used for SCSI peripherals today.

If you are having SCSI conflicts:

• Change the order of your SCSI devices in the daisy chain.

Because of the varying SCSI standards in use for SCSI peripherals, some SCSI conflicts may be resolved by moving the scanner and other SCSI peripherals to different positions in the chain.

• Check the SCSI ID number of your SCSI devices. Make sure

that no two devices have the same ID. The SCSI check feature in the CS-600 PtP scanning software can tell you what the IDs are of the devices in your SCSI chain.

• Use a shorter cable (4 feet or shorter) for each segment of the

chain. The use of longer-than-authorized cables accounts for more than 50% of SCSI-related problems.

• Make sure that none of the middle SCSI devices are terminat-

ed, and make sure that only the last SCSI device is terminated.

• Always terminate the last device in your SCSI chain with an

external terminator and not an internal terminator.

1-10

Operating the scanner

• Performing the power-on self-test

• Positioning a document

• Scanning thick documents

• Notes on using the TMA and ADF scanner accessories

Performing the The power-on test is a quick self-checking mechanism that the power-on test scanner carries out after you turn it on.

This is what happens after the scanner is turned on:

1 POWER indicator on the front panel of the scanner lights up.

2 READY indicator beside the POWER indicator flashes briefly.

After a 30-second warm-up period, the scanner carries out a self-test, with the scanner carriage moving back and forth about a half-inch. If no problems are detected, the READY indicator stays lit.

Note:

If there are problems with the POWER and READY

indicators, see the Troubleshooting section in the Appendix.

3 The fluorescent lamp inside the scanner should be on too by

this time. The lamp should never go off while the scanner is on.

Note:

If the scanner lamp doesn’t come on, starts to flicker,

or gets dim, see the section Replacing the scanner lamp at the end of this chapter.

Positioning 1 Lift the scanner cover. a document

Place the document face down on the scanner glass. The top left corner of the document (when the document is held upright for normal reading) should be at the "0,0" position on the ruler guides running alongside the scanner glass.

Hardware installation 1-11

Scanning thick 1 Lift the scanner cover high enough so that there is documents enough room to place the document on the scanner glass.

2 Lower the scanner cover. You are now ready to start scanning.

Using scanner Your scanner is a powerful imaging device, but there are accessories scanner accessories available that can enhance your scanning

efficiency.

• The Transparent Media Adapter (TMA) doubles the power of

your scanner as it allows you to scan transparencies. TMAs have their own source of lighting, which is crucial to scanning transparencies as it prevents images from being exposed to too much lighting and getting washed out as a result.

Although 35-mm slides and filmstrips are not recommended due to their small size and lack of resolution, you can use the TMA to scan slides ranging from 35-mm slides and filmstrips to transparencies as large as 8"x10".

Miscellaneous

• Returning your scanner

• Locking the carriage

• Replacing the scanner lamp

• Returning your scanner

Your Polaroid scanner has been built to exacting standards. Just like any piece of electrical equipment, however, your scanner or the delicate parts in it are subject to wear and tear, and may malfunction for any number of reasons. If your scanner needs to be serviced or repaired, do the following:

For U.S. users:

• Call Polaroid Technical Assistance (see page 1-3) to get a

Repair Merchandise Authorization (RMA) number.

• Lock the carriage (discussed in the next section)

• Pack the scanner in the original box without any software,

and send the interface cables if applicable. If you have lost the original box, you will need to buy one from Polaroid for a nominal fee.

• Send the scanner to Polaroid

Important:

Make sure the RMA number is on the address label and is visible. Packages without an RMA number or with the wrong RMA number on the outside of the box will be refused and returned to sender.

For Canadian users:

Call Polaroid Technical Assistance (see page 1-3). You will be given an RMA number and address to where your scanner can be sent for repair.

For users in parts other than the U.S. or Canada:

Call your authorized dealer for further instructions.

Hardware installation 1-13

Locking the carriage You need to lock the scanner carriage if you wish to ship back

your scanner for any reason. The carriage must be locked to prevent the mechanism from moving during shipping and getting damaged in the process.

In addition, you need to pack the scanner in the original box in which it came. No scanner will be accepted in a packaging other than the authorized Polaroid packing box. If your box is lost, call Polaroid Technical Assistance (see page 1-3) to purchase a new one.

Important:

Polaroid will not be liable for scanners that are damaged during transit because the carriage had not been locked or was not packed in the original or authorized packaging.

Locking the scanner:

1 Turn the scanner off and then back on. The carriage will

move forward a bit and then return to its standby position. When the carriage stops moving, turn off the scanner. Be sure that the carriage is in the standby position before you tighten the locking screw. Otherwise, the carriage won’t be locked properly and can get damaged during shipping.

2 Turn the scanner on its side and locate the locking screw at

the bottom of the scanner. To lock, turn the locking screw clockwise one-fourth turn while pushing it in simultaneously. The screw should stay in and not pop back out.

3 Reference

Overview

The CS-600 PtP scanning software is the program that acts as a bridge between your scanner and a target application, such as Adobe Photoshop or MicroFrontier Color It.

In practical terms, this means you use the CS-600 to capture images placed on your scanner, edit those images, then place them in your target application. And with its many editing tools and features, the CS-600 can save you considerable time from having to do touch-ups in your image-editing software.

3-1

This section is a listing of features found in the CS-600 PtP scanning software.

The reference information is organized in four parts, following the structure of the software which shows the four major windows. The subjects covered in this section include the following:

• The CS-600 Software Plug-in

• Preview Window

• Settings Window

• Information Window

• Scan Job Window

Here are some of the things you can do with the CS-600 PtP:

• Select the type of image to be processed and scanned. You can

put one type of image on the scanner and scan that in its original form, or you can scan it in another form altogether. For example, you can have a color photo and scan it in the same color mode, or you can scan it in a different image type such as grayscale or line art.

• While in preview mode, the image can be adjusted through

the image-enhancement tools in the Settings window. These tools allow you to adjust image features such as brightness, contrast, and exposure; shadows and highlights; gamma or midtones (mid-gray levels); hue or saturation; and apply various filters for special effects.

• Clicking on an image-enhancement tool calls up the Advanced

Image Enhancer (AIE) dialog box. While in the AIE dialog box, you can see thumbnail displays of the image, make changes and see the effects applied in real time (see “before” and “after” versions instantly). You can also switch to another tool without leaving the AIE dialog box, as well as switch among scan jobs if you have multiple scan jobs. The imageenhancement functions are among the most powerful features of the CS-600.

3-2

• Perform a preview or preliminary scan. This is done with the

Preview button in the Preview window, and it allows you to see a preliminary view of the image before it’s actually scanned. Previewing an image allows you to do further enhancements if necessary, and it also lets you select the final area to be scanned in case you wish to crop the image. When the image is ready to be scanned, clicking on the Scan button will activate the scanning process, and the image will then be delivered to your target application.

• When changes are made to the image, the changes can be easi-

ly verified through the Information window, which displays changes to RGB values. This information can be helpful for those working with color values.

• Create multiple scan jobs. A scan job is simply a task that you

designate the scanner to process and scan. For example, one scan job may be in grayscale and another may be in color. The two scan jobs can then be manipulated and scanned separately, and you can switch between scan jobs easily while making changes. The CS-600 Software Plug-in’s ability to process various scan jobs concurrently adds tremendous flexibility to scanning.

The CS-600 PtP

The CS-600 PtP consists of four major windows: Preview, Settings, Information, and Scan Job.

The Preview and Settings windows appear automatically after the CS-600 is started up. The Scan Job and Information windows, however, are hidden, and to see them, go to the View menu in the Preview window and click on the commands

a Settings window contains scanning parameters for outputting

the image and includes image-enhancement tools.

b Scan job window provides key functions in processing scans.

c Preview window has commands and tools for controlling the

scanner.

d Information window provides information on the preview

image.

3-4

To bring up the CS-600: Start up your image-editing software. When the application

opens, choose Acquire from the File menu, and choose CS-600 from the submenu.

On the very first time that the CS-600 is started up, only the Preview and Settings windows will appear. To see the Scan Job and Information windows, go to the View menu and choose the Show command for both windows.

The next time you start up the CS-600, the screen will look exactly like the last time you exited the software. This means that if you had all four windows open the last time you quit the CS-600, the same four windows will appear the next time you start it up.

The full page preview is a preview of your image as defined by the parameters set in the Preview Setup command (in the Preferences menu). For instance, if your image is 8"x 5" but the dimensions in the Preview Setup are 4"x 3", your full page preview will be 4"x 3".

The maximum size of the full page preview varies, depending on your scanner model. For example, if the scan bed (the glass surface) of your scanner has a maximum size of 8.5" x 11", the maximum full page preview will be limited to those dimensions.

The size of the full page preview can be changed by setting new dimensions in the Preview Setup command. The new dimensions will take effect, however, only with the next preview. This means you need to click on the Preview button so that the scanner does a new preview; only then will you see the new dimensions of the full page preview.

3-10

You may wish to change the size of your full page preview to improve performance and save memory. A smaller preview area will occupy less memory, speed up processing, and yield a higher-resolution preview. This is because the CS-600 takes your preview image and dynamically calculates how best to display that image in the smaller preview area — resulting in a higher-resolution view.

Reference 3-11

To use full page preview:

1 Full page preview is the default view. It will be dimmed if the

current view is already the full page preview. It is available for use only if you are in zoomed preview mode.

2 To change the size of the full page preview, click on the

Preview Setup command in the Preferences menu. When the Preview Setup dialog box appears, specify the new dimensions for the full page preview. (See the Preview Setup command for more details.)

3 To make the new preview dimensions take effect, do a new

preview by clicking on the Preview button, and in a few moments, the new preview area will appear.

Zoomed Preview This command displays the magnified view that results from

using the Zoom Preview tool. The zoomed preview is the view of a specific part of the image

shown in higher resolution with more visible detail. If you have zoomed preview enabled, the view is stored in memory, and you can easily switch between full page preview and zoomed preview.

The zoomed preview is different from the zoomed-in view obtained from the Magnifying Lens tool. The zoomed-in view is simply an enlarged view, but it is not in high resolution.

To use zoomed preview:

1 Click on the zoom preview tool (leftmost tool in the Toolbar

that looks like a microscope).

2 Move the pointer to the preview image and draw a scan frame

around the area to be zoomed in, then click inside the scan frame. The selected area will be magnified to give you the zoomed preview. For more details, refer to the section on the Zoom Preview tool.

After you use the zoom preview tool to create the zoomed preview, the Zoomed Preview option in the View menu will be enabled. You can then switch between Full Page Preview and Zoomed Preview as your viewing modes.

Resize Window to Fit This command adjusts the preview window to fit the preview

area. In the example below, the preview window is larger than the

preview area, as the gray space (which denotes the preview window) exceeds the white area (which denotes the preview area). The preview window can also exceed the preview area if, for instance, you manually enlarged the preview window (by dragging on the resize box). If you find that the gray area is far too big and wish to utilize window space more efficiently, use this command to resize the preview window.

b Window resized. Note lower half of window has disappeared

(gray area gone) to fit the preview area. Gray area on right side of window is still left because window width is already at its minimum.

Reference 3-13

To use this feature: Choose the command Resize window to fit in the View menu.

You can also do this by pressing Command + R (the Apple Command and R keys) simultaneously.

This command is available only if the current zoom level is 100%, and is disabled if zoom is set to other levels. To verify the zoom level, open the Information window and look up the zoom level.

Show / Hide commands These commands allow you to switch between showing or

hiding the Settings, Scan Job and Information windows on your screen.

To use this feature: The Show / Hide commands are toggle commands, which

means they can be used to show or hide a window, as the case may be.

Tip:

Another way to close or hide an active window is to click

in the close box on the left corner of the active window. This is the same as using the Hide command.

Preferences menu

The Preferences menu lets you:

• Choose the correct scan material

• Create effects like invert and mirror

• Create cursor lines to help you with alignment

• Control the size of your preview window

• Keep your scan module after you finish scanning

• Create a smoked glass background to help distinguish the

active scan frame

• Set other options, such as specifying a working directory

for files

Scan Material This command allows you to select the correct scan material.

Scan materials can be generally classified into three types:

• Reflectives, such as photographs or prints.

• Positives, such as slides.

• Negatives, such as the negative film you use for your camera.

The default scan material selection depends upon the scanner you’re using, and the choices available to you in the Scan Material submenu will also depend on your equipment.

For instance, the positive option appears only if you’re using a Transparent Media Adapter (TMA) with your scanner. The negative option appears only if you have DCR installed and are using the TMA to scan a negative.

Reference 3-15

If you are scanning negatives or positives, make sure you specify the correct scan material, or you will get inaccurate scanning results.

Note:

The Scan Material function is also related to the Tints tool, an image-enhancement function in the Settings window. Refer to that section for more details.

To use the scan material feature: Choose the Scan Material command in the Preferences menu.

From the submenu that appears, select your scan material. A check appears next to the selected option. The option you select will also be shown in the Scan Material Status icon (discussed on page 3-17).

Note:

If your Preview window is close to the right edge of your monitor, the Scan Material submenu may appear on the left side instead of on the right (as shown above). To resolve this, move the Preview window towards the left to create enough room for the submenu to drop down on the right.

3-16

The Scan Material Another way to access the Scan Material menu is to use the Status icon Scan Material Status icon, located to the right of the Scan

Button.

Scan Material Status icon

The appearance of the Scan Material Status icon changes, depending on whether your scan material is reflective, positive, or negative.

The positive and negative icons become active only if you’re using a Transparent Media Adapter with your flatbed scanner.

• If you’re scanning a reflective (such as a photo or print), the

Scan Material status icon appears in the form shown at left. When you click on the icon and hold down the mouse, you’ll see the Reflective option checked.

• If you’re scanning a positive transparency or filmstrip, the Scan

Material Status icon appears in the form shown at left. Notice the perforations on the top and bottom of the icon (characteristic of slides) to distinguish it from the reflective icon. When you click on the icon and hold down the mouse, you’ll see the Positive Transparency option checked.

• If you’re scanning a negative transparency or filmstrip, the

Scan Material status icon appears in the form shown at left. When you click on the icon and hold down the mouse, you’ll see the Negative Film option checked.

Reference 3-17

Invert This command creates a negative of an image. The Invert

effect is applied to the whole preview image; it cannot be used for only a specific portion of the image.

When an image is inverted, the brightness value of each pixel is converted to the inverse value on the 256-step color values scale. For example, a pixel in a positive image with a value of 255 is changed to 0, and a pixel with a value of 5 is changed to 250.

Original Invert

To use this feature: Choose the Invert command in the Preferences menu. A check

appears next to the command when it is enabled.

Horizontal Mirror This command allows you to flip the image so that a mirror

effect is created. The Mirror effect is applied to the whole preview image; it cannot be used for only a specific portion of the image.

Original Horizontal Mirror

To use this feature: Choose the Horizontal Mirror command in the Preferences

menu. A check appears next to the command when it is enabled.

3-18

When the mirror image appears, the scan frame will still be in the old location, and you will need to move the scan frame if you wish to define another area.

Cursor Auxiliary Lines This command allows you to create horizontal and vertical

grid lines with your cursor to help define a scan frame precisely. Using the grid lines, you can read the measurements off your ruler more easily.

Cursor auxiliary lines on the x and y axis

To use this feature:

1 Choose the Cursor Auxiliary Lines command in the

Preferences menu. From the submenu that appears, select how the cursor lines will appear.

• On both x (horizontal) axis and y (vertical) axis

• On x axis only

• On y axis only

• None (no cursor lines)

Note:

If your Preview window is close to the right edge of

your monitor, the Cursor Auxiliary Lines submenu may

Reference 3-19

appear on the left side instead of on the right (as shown above). To resolve this, move the Preview window towards the left to create enough room for the submenu to drop down on the right.

2 Click on the Scan Frame tool.

To see how the cursor lines work, draw a scan frame. Click on the top left corner of the image as your starting point, then drag down to form a scan frame.

As you draw the scan frame, cursor lines will appear to help you draw the scan frame precisely.

When you release the mouse, your scan frame will be aligned with the cursor lines.

a Click on the Scan Frame tool, then define a starting point.

b Cursor lines appear to the top and left of the image.

a Live Preview This option applies only to color scanners. If

Live Preview is enabled, the next option, Color Preview, will be dimmed.

If Live Preview is on:

• Changes you make to the preview image are shown instantly

(for example, switching from color to grayscale).

• If you’re scanning in grayscale and live preview is on, the

image appears in color unless you specifically change image type in the Type box (in the Settings window) to a grayscale mode. This happens because Live Preview always does previews in color.

If Live Preview if off:

• Your preview will be in accordance with your image type

(i.e., if you have a grayscale image, your preview is in grayscale; with a color image, you get a color preview). If you apply any image-enhancement control, the changes will not be apparent until you do a new preview (click on the Preview button again). Turn off Live Preview if you’re previewing or scanning in grayscale to speed up the process.

Reference 3-21

b Color Preview This option applies only to three-pass color

scanners, and is enabled only if Live Preview is not selected. If this option is turned on, the image will be scanned in whatever scan mode is specified in the Type box (in the Settings window). If it is turned off, the image will be scanned in grayscale.

c Fast Preview This option allows you to choose your preview

mode.

• If Fast Preview is on: The preview process is faster, but the

quality of preview image is a little coarse.

• If Fast Preview is off: The preview process is slower, but the

quality of the preview image is improved. The Fast Preview option is a hardware-related feature and

may or may not be available depending on your scanner model.

The Preview Area The Preview Area option in the Preview Setup dialog box lets

you select the size of your preview area. Choose from the following options: letter, A4, legal, maximum size, or custom size.

• Maximum refers to the maximum scan area that can be sup-

ported by your particular scanner model.

• Custom will appear if you type in your own specifications

and change any of the edit boxes.

• The Top, Left, Width and Height edit boxes allow you to

specify the dimensions of the preview area. Top and Left refer to the starting points of the preview area on the x and y coordinates. Width is the expanse of the preview area, and Height is the depth of the preview area.

• The unit of measurement, indicated on the right side of the

Left box, reflects the unit selected in the Settings window.

To use this feature: Choose the command Retain Scan Module after Scan in the

Preferences menu. A check appears next to the command when it is enabled.

Smoked Glass Background This command helps you distinguish the scan frame from the

rest of the material for greater visibility of the scan frame. With this feature turned on, the part of the image within a

scan frame will stand out, while any material not in a scan frame is relegated to the smoked glass background. If you have multiple scan frames, all the scan frames will be visible, and the current scan frame will be denoted by the marquee (marching ants).

The Smoked Glass Background, then, helps you focus on just the part of the image to which you wish to apply controls or scan.

Moreover, if you have multiple scan frames and each one has a different setting (one in grayscale, another in color, etc.), this is also shown clearly if smoked glass is turned on.

Action buttons

The Preview button gives you a preliminary view of the image on your scanner.

Previewing an image gives you greater flexibility, as it allows you to apply various controls to the preview image before actually scanning it in. With the preview image displayed, you can apply image enhancements or crop the image before performing the final scan.

The Scan button lets you scan in the image in your scanner and delivers it to your image-editing software. The scanned image is based on the specifications you have chosen in the Settings window and on controls you may have applied to the preview image if a preview was performed.

If you wish to keep the scan module (the CS-600 Software Plugin) after a scan is completed, check the command Retain Scan Module After Scan, located in the Preferences menu in the Preview window.

For applications that support scan-module retention, the Plug-in windows reappear after a scan is delivered to the image-editing software.

Rulers The rulers on both sides of the preview window help you with

operations that need precise measurement and alignment of your image.

The unit of measurement in the rulers is determined by the unit of measurement selected in the Image Dimension controls, located in the Settings window. Depending on your chosen unit of measurement, the rulers can mark off measurement in these units: inch, centimeter, millimeter, point, and pixel. The pixel option is dimmed if the selected resolution unit is lpi.

The rulers will change when you alter the dimensions of the preview area in the Preview Setup command (in the Preferences menu). For example, if you change the preview area size from 5"x 8" to 6"x 9", the rulers will change accordingly.

Output Image Parameters The Output Image Parameters include the various controls

that determine how your image is scanned and processed. The Output Image Parameters include:

• Type

• Resolution

• Image Dimension controls

Type (Image Type or Scan Mode)

The Type menu determines what your resulting scan will be. It does not refer to the original image mode. For instance, if you have a color photo but choose 256 grayscale for the scan mode, the photo is scanned and processed as grayscale.

Note:

The options Billions of colors and 1000’s shades of

gray are available only for 36-bit scanners such as the CS-600.

Only a few applications in the market today (such as Photoshop 3.0) support these two options. Do not select these options unless they are supported by your applications; otherwise, you will obtain completely distorted images.

To use the Type menu:

• From the Type menu select the image type for your final scan.

Choose the correct image type, as the wrong choice will simply create bigger files that won’t be of any use to you. For instance, if you have a grayscale original, do not set image type to Millions of colors.

• If you select Halftone, choose the halftone screen as well from

the submenu.

Reference 3-37

Note:

The image you obtain when you choose Halftone may not look clear in the preview. To see what it actually looks like, you may need to scan it in.

Halftone Patterns The various halftone patterns give you an array of effects for

your image. For example, the 53-dot screen works well for most pictures, and was designed for printing on a 300-dpi laser printer. The mixed- page pattern is good for displaying images on low-resolution output devices. Other options like horizontal and vertical line provide special effects that add flair to your printouts.

Resolution

Resolution in the Settings window refers to the desired resolution for outputting the image to a device, such as a monitor or printer. It does not refer to the resolution in which the image is scanned. The maximum output resolution is dynamically calculated by the system as determined by the maximum scanner resolution and the scaling setting.

Resolution is also related to scaling, or how large or small the image will be scanned relative to the original. When you change the resolution, the scaling may be affected slightly if the resolution you selected has no exact equivalent in scaling. (Scaling is discussed in the next section, Image Dimension controls.)

For details on choosing the optimal resolution and how resolution relates to scaling, see the Basic Concepts chapter.

To set your resolution: Enter a resolution setting in the Resolution edit box. There is

no need to press the Enter key; typing in a value automatically inputs it into the system. If the value you enter is too low or too high, the minimum or maximum resolution value is entered for you instead.

Note:

In setting resolution, choose the setting that best matches your output device. Remember that the higher the resolution, the larger the resulting file will be and the longer it will take to output.

Reference 3-39

Unit Selection

The unit of measurement for resolution is in dpi (dots per inch) or lpi (lines per inch). Lpi settings are dimmed if the ruler unit is in pixels.

To select your option:

• Choose dpi if you know precisely the resolution you need for

your image. For more details on resolution, see the Basic Concepts chapter.

• Choose lpi Draft to produce resolution that is one times the

screen frequency (no higher than 72 pixels per inch). Draft quality may result in output images that look a little blurred or indistinct at edges.

• Choose lpi Medium to produce resolution that is one and

one-half times the screen frequency (no higher than 72 pixels per inch).

• Choose lpi Final to produce resolution that is two times the

screen frequency.

Image Dimension These controls allow you to adjust the various factors that controls affect the image, including the width and height of your image

when it is first scanned (input), the scaling factor, and the dimensions of the image when it is finally output.

a This is a mathematical formula expressing the relation of the

scan frame that you draw. For example, if the image on your

scanner is 5" x 7" and you draw a scan frame that is 3" x 4", then your input width will show 3.000 and your input height will show 4.000.

• Output width and output height refer to the dimensions of the

image when output to an output device (such as a monitor or printer).

The input width, input height, output width, and output height are affected by your scaling and whether or not the Aspect Lock is on. For more details, see the sections How to

use Input-Output dimensions and How to use the Aspect Lock.

b The Aspect Lock allows you to keep the ratio of the image

width and height constant. (For more details, see the section How to use the Aspect Lock on the following pages.)

c The Size indicates how big the file will be when you accept the

dimensions shown in the edit boxes, together with the resolution setting that you selected. Size is calculated automatically.

d The Unit of Measurement allows you to select your unit of

measure. The options include inch, centimeter (cm), millimeter (mm), point, and pixel.

e The Scaling control lets you create large or small images so

that the images don’t have to be resized subsequently, which is usually done in your image-editing software. For more details, see the Basic Concepts chapter and the Scaling section in the following pages.

To use the Image Dimension Controls:

• Select the unit of measurement.

• Enter a value in the applicable edit boxes (width input, height

input, scaling, width output, height output).

How to use the Input-Output dimensions

The Input-Output dimensions consist of four edit boxes: input width, input height, output width, and output height. These edit boxes are linked to the use of the Aspect Lock, and the boxes may or may not be edited depending on whether the Aspect Lock is on or off. Below are the details.

Reference 3-41

• Use the input dimensions to specify your scan frame; or if you

wish, you can simply drag on the scan frame to whatever size you want, and the dimensions will be reflected in the input width and height boxes.

The input dimensions can be changed only if your Aspect Lock is off, and this is evident because only the input dimensions have edit boxes around them. The output dimensions have no boxes around them, indicating that they cannot be edited at this point. The output boxes, however, will respond to changes in the input boxes (and scaling).

Aspect Lock is off

With Aspect Lock off, only input dimensions can be edited.

• The output dimensions determine the width and height of

your image when output to an output device such as a monitor or printer. The output dimensions can be changed only if the Aspect Lock is on.

The output dimensions are calculated dynamically, and the system looks at other variables such as your resolution and scaling to determine the final output dimensions. This means that you may specify output dimensions of 5"x 7", but because of intervening variables, the actual output dimensions may be 4.85"x 6.9" — which is the closest the system can produce given your other variables.

3-42

Aspect Lock is on

How to use the Aspect Lock

With Aspect Lock on, only output dimensions can be edited.

The Aspect Lock preserves the ratio of the image width and height from input to output. For instance, if your image is

2 inches wide by 4 inches high, changing it to 1 inch by 2 inches will maintain its aspect ratio. Changing it to, say, 1 inch by 4 inches, however, will alter its aspect ratio, so that the image will be narrower than the original. The notes below provide more details on how to use the Aspect Lock.

The Aspect Lock is a toggle. Click on it to lock or unlock.

• If the Aspect Lock is ON: Changing one output edit box

(width or height) will automatically change the other output field, as well as scaling, to preserve the aspect ratio. With Aspect Lock on, you cannot edit the input dimensions.

b Changing one output field will change the other. Note that

aspect ratio is preserved (input 2x4; output 4x8). Scaling also changed automatically.

• If the Aspect Lock is OFF: Changing one input edit box

(width or height) will NOT automatically change scaling or the other input field, and aspect ratio can be changed. With Aspect Lock off, you cannot edit the output dimensions.

a Aspect Lock is off.

b Changing one input field will not automatically change the

other. Note aspect ratio is not preserved (input changed from 2x4 to 3x4).

Reference 3-43

Scaling Scaling is the process of creating larger or smaller images in

your scanning software so that you need not resize the images later when they are delivered to your image-editing program.

To illustrate the use of scaling: Assume that your input dimensions are 4" x 5", then:

• If scaling is at 100%, output dimensions will also be 4" x 5".

• If scaling is at 50%, output dimensions will be halved — to

2"x 2.5".

• If scaling is at 200%, output dimensions will be doubled — to

8"x 10". The above assumes that your resolution is held constant

throughout the changes. When you change resolution and specify a value that has no exact equivalent for scaling, the scaling may be affected and adjusts itself to the nearest allowed value. For instance, if your resolution is 100, your scaling becomes 99 (instead of a full 100), because that is the closest scaling equivalent, given the resolution value.

Image-adjustment The image-adjustment controls include the Auto button and controls the Color Correction button, located below the Image

Dimension Controls.

Auto (Automatic Contrast Control)

The Auto button optimizes the contrast of scanned images by making adjustments to the Shadow/Midtone/Highlight values.

The Auto button will be dimmed if the image type selected in the Type box is line art or halftone.

How Auto settings are applied

The Auto setting works by calculating the image settings of the current scan frame and applies those settings to the current scan frame.

If you draw a scan frame around part of an image that is light and then apply Auto, that part of the image within the scan frame becomes darker. This is because Auto remaps the pixels to a broader range, so that light pixels are spread further apart. The result is a darker image.

3-44

Conversely, if your scan frame encloses a darker part of the image and then you apply Auto, the part of the image enclosed within the scan frame becomes lighter. The dark pixels are remapped to a broader range, resulting in a lighter image.

b The Entire image has lightened with Auto applied, based on

settings of the image part within the scan frame. When you use Auto, It is helpful to turn on the Smoked Glass

Background feature on (in the Preferences menu in the Preview window). This will allow you to see clearly the part of the image within the current scan frame.

To use the Auto control:

1 Click on the Preview button to preview the image.

2 Click on the Scan Frame tool, and draw a scan frame of the

area where Auto will be applied.

3 Click on the Auto button in the Settings window. The button

will light up, indicating that Auto has been applied. If you do not like the results obtained by Auto, or if you

choose not to use it for certain images that have Auto enabled, click on the Auto button again to deselect the feature. A message will appear, asking if you wish to reset the Shadow/highlight/midtone values; click Yes. This will return your image to the original.

Important: Do not use the Auto setting with the Color Correction feature (discussed in the next section).

Note:

To see how color images compare with and without the

Auto control, see the color pages in this manual.

Color Correction

This tool applies a color correction profile to your images to give them accurate, lifelike color. However, if you have Polaroid’s Print to Press color calibration and correction system installed, the Color Correction button will override the generic color paper profile and apply Print to Press to the image.

A generic color profile is provided with the scanning software to correct the minor color shifts that occur invariably with scanners. To achieve optimal color correction, however, you need a true color calibration and correction system like Polaroid’s Print to Press developed expressly for this purpose.

Polaroid creates an industry-standard color profile for nonPolaroid materials, matched to your scanner, so that colors in your scanned image are adjusted to their optimal levels.

Image-Enhancement tools

The image-enhancement tools are an integral part of the CS-600 PtP scanning software. With the image-enhancement tools, you can adjust the characteristics of your image such as brightness and contrast, or shadows and highlights, right from within the CS-600. If these tools were not available, image enhancement would have to be done instead in your imageediting software. Thus, the image-enhancement tools in the CS-600 adjust images right within the scanning software.

3-48

When you click on an image-enhancement tool, a dialog box called the Advanced Image Enhancer (AIE) appears, with a screen corresponding to the image-enhancement tool you selected. The AIE dialog box allows you to perform several functions, including the following:

• View image-enhancement changes in real time. The AIE dia-

log box has two thumbnails — providing you with “before” and “after’ versions of an image.

• Switch among image-enhancement tools without leaving the

AIE dialog box.

• Switch among scan jobs to apply image enhancement.

• Reset or revert settings, providing you the flexibility to cancel

out changes or restore to default settings if needed. Although you can use all the image-enhancement tools, you

don’t need to use every one of them to achieve a great image. Perhaps all that’s needed is a change in the shadows or gamma curve. Try experimenting with the tools to see which one provides optimal results.

Take note too that the effects of the image-enhancement tools are cumulative. It’s important to remember this because the cumulative effects affect the image in a way that is totally different than if only a single image-enhancement tool was used.

Example:

If you increase brightness in an image (through the Brightness Contrast and Exposure tool) and then modify the gamma curve of the image (through the Curve tool), the curve will be based on the altered brightness settings.

Using the Advanced Image Enhancer dialog box

When you click on any of the image-enhancement tools in the Settings window, the Advanced Image Enhancer (AIE) dialog box appears. Functions of this box, include the following:

1 This is where you select the scan job to which image enhance-

ment will be applied. (Note: For definition of a scan job, see the Scan Job section of the Reference.) If you have multiple scan jobs, you can switch among the various jobs, and the thumbnails will change accordingly to show the selected scan job.

Important:

Switching to a new scan job while using the AIE dialog box will make any changes to the currently selected scan job permanent. This cannot be undone even by selecting the Cancel button.

Example:

Assume you have two scan jobs, Scan Job 1 and Scan Job 2. If you applied a filter (through the Filters tool) to Scan Job 1, and then switch to Scan Job 2, the filter will be applied to Scan Job 1 even though you did not click OK. To undo the filter, you will need to use the Reset button. See next page on how to use the action buttons for more details.

2 These are the thumbnails of the image captured by your scan-

ner. The left thumbnail is the “before” version — which shows the effects of the last saved settings values. The right thumbnail is the “after” version — which shows the effects of the new settings added in the AIE.

3 To select another image-enhancement tool, click on any of the

buttons displayed in the vertical toolbar on the right side of the dialog box.

4 Click on an action button to achieve a particular effect. (See

next page for more details.)

c Click on a button for an action.

d Choose your scan job here.

The Action Buttons The Action buttons in the AIE dialog box (item c in preced- in the AIE dialog box ing illustration) carry out a specific action. Below are the

details.

The OK button.

Clicking on this button will apply whatever image enhancements you have performed on the current scan job, and close the AIE dialog box. Clicking OK is not the same as switching to another scan job (if you have multiple scan jobs). If you switch scan jobs, the effects are applied to your current scan job, and then the new scan job appears; you do not exit the AIE dialog box.

Example:

If you increased brightness, changed the saturation, and then clicked OK, all the changes are applied, and you exit the AIE dialog box.

The Cancel button

Clicking on this button will cancel out all image-enhancement changes you have made to the current scan job, and then close the AIE dialog box.

3-52

Example:

If you applied filters, changed the curve, and then clicked Cancel, none of the changes will take effect, and you exit the AIE dialog box.

The Reset button

Clicking on this button brings up the Reset dialog box, where you can specify which settings are to be reset, then click Reset or Cancel. If Reset is selected, the settings are restored to their default values; if Cancel is selected, the operation has no effect.

Select the settings to be reset, then click Reset. The selected settings are restored to their default values.

Example:

If you changed shadows/highlights, changed brightness, then clicked on Reset and chose to reset brightness, the brightness setting of the scan job is restored to its default; but the altered shadows and highlights remains in effect. If you reset both shadows/highlights and brightness, then those values are both restored to default.

The Revert button

Clicking on this button cancels out the changes you made with the current image-enhancement tool. This means that if you used several tools (and achieved a look that is the cumulative effect of all the tools), using Revert will cancel the effect of only the current tool and preserve the effects of the other preceding tools.

Example:

If you changed shadows, applied filters, changed brightness, then clicked Revert, the brightness changes will be cancelled out, but the altered shadows and filters settings remain in effect.

image. Brightness is the balance of light and dark shades in an image,

while contrast is the range between the darkest and lightest shades in the image. On the other hand, exposure works like the exposure feature in photography, allowing you to change exposure of the image by increasing or reducing available light to the image. The Exposure control is a scanner hardwarerelated feature, and using it correctly can allow more detail to emerge in an image, especially if it was underexposed.

The goal in using the BCE tool is to get the fullest dynamic range possible for your image. Because the BCE tool affects the image as a whole, you can try using the Shadows and Highlights tool instead to get the effects you want if you find that the BCE tool alters your image too much.

• Too much brightness can make an image look washed out.

• Very low brightness levels can make an image look very dark.

Threshold

The BCE screen (for line art)

In line art mode, the method for determining how gray levels are converted to black and white is through the Threshold adjustment control.

The threshold is the dividing line between black and white, with the value 128 (the middle gray level) as the determining point.

• Gray levels below the threshold are converted to black, result-

ing in a low-contrast, black-and-white representation of the image.

• Gray levels equal to or above the threshold are converted to

white, resulting in a high-contrast, black-and-white representation of the image.

To use the Threshold feature, do either of the following:

• Enter a value in the Threshold edit box; or

• Drag the black triangle above the threshold edit box to the

tool applies only to color images and is not available for use with grayscale or black-and-white images.

Hue is the aspect of color that distinguishes one color from another (whether it is red, green, or blue). In the RGB color model, hue can be distinguished by its position in the color wheel.

Saturation, on the other hand, refers to the intensity of a color (more red in an apple, more green in the grass). Increasing saturation can have a dramatic effect on the colors of an image, but beware of increasing saturation too much, as it creates artificial-looking, overly bright colors.

The Tints tool is useful when your image has a particular color cast and you wish to remove the cast to make the image look more natural. The Tints tool is also related to the Scan Material command in the Preferences menu. For reflectives or positives, the Tints tool lets you adjust hue and saturation. For negatives, the Tints tool provides additional controls for selecting film type and adjusting exposure.

To use the Tints tool:

1 Select the correct scan material for your image in the Scan

Material command in the Preferences menu. The options available to you will depend on the scanner equipment you’re using and certain modules that need to be installed. For more details, refer to the Scan Material section.

b The Exposure Correction bar lets you adjust the exposure of

a negative. An overexposed negative looks dark (with the image itself in the dialog box appearing bright), while an underexposed negative appears light (with the image itself appearing dark).

• If your film is overexposed (image is too bright), drag the bar

to the left; this will make the image darker.

• If your film is underexposed (image is too dark), drag to the

bar to the right; this will make the image lighter.

c The Film Type Selection bar allows you to select the type of

film you used for your negative. Choosing the correct film type is important in maintaining image quality, and you should choose the film type that’s indicated on the packaging that came with your film.

The Film Type Selection box provides several choices for you to choose from. If your type of film is not in the list but a similar film type from the same company is available, you may choose from one of them. Very often, similar films from the same company use identical film types. For example, Kodak 135, ASA 100, ASA 200, and ASA 400 are grouped as the same type — ASA 100.

If your film type is not in the selection list and you cannot find its family group, choose Generic Negative Film.

d The Color Wheel shows you the position of colors — green

is across from magenta, and red is across from cyan. By moving the pointer (a small dot) to a place in the color wheel, you alter the hue of the image. For instance, if you move the pointer towards the green area of the wheel, the image will acquire a greenish cast.

Shadows and The Shadows and Highlights tool lets you change the shadow Highlights tool and highlight points of an image.

Usage: To change the shadow and highlight points of an image.

By using this tool, you can manipulate shades so that the Shadow point becomes the new darkest value and the Highlight point becomes the new lightest value. Shades that are darker than the shadow then become black, and shades lighter than the highlight become white. For example, if you set the highlight point to 200, all points in the image with a value greater than 200 will be mapped to a value of 255, since 255 represents the “whitest” white.

The Shadows and Highlights tool can be used for both grayscale and color images. If you have a limited range of grays between your lightest and darkest point, using shadows and highlights will have the effect of extending the range of grays and make more detail in the image visible. This tool is not available for use with line art or halftone scan modes.

The Shadows and Highlights screen

The Histogram is a graphic representation of how all the pix-

els in an image are distributed across brightness and darkness levels. The darkest pixels are at the left; the lightest pixels are at the right.

• A histogram skewed heavily to the left indicates that the

image has many more dark pixels than light.

• Conversely, a histogram skewed heavily to the right will indi-

cate a light image as it has more light pixels than dark.

• The height of the histogram indicates the number of pixels at

that point in the histogram.

b The Triangles (indicators) below the histogram adjust the

Shadow, Midtone, and Highlight settings.

• The black (left) triangle controls the shadows. Moving this tri-

angle to the right will emphasize shadows and create a darker image.

• The gray (middle) triangle controls the midtones and indicates

how the brightness and darkness pixels are divided. Moving it to a value less than 1.0 will have the effect of darkening the image. Moving it to a value greater than 1.0 will have the effect of lightening the image.

• The white (right) triangle controls the highlights. Moving this

triangle to the left will emphasize highlights and create a lighter image.

Note:

The gray and white triangles will change in color if a

color channel (not Master) is selected in the Channel box.

Reference 3-63

c The Histogram bar shows the distribution of shades from

dark to light (left to right). The distribution of shades changes as you move any of the triangles.

d Output edit boxes show the 0-to-255 pixel range to where

the Input levels are mapped. For example, if you modified input values to 30 and 255 and then change output values to 0 to 250, the input values of 30 to 255 will be “stretched” to fit the output range of 0 to 250. This means you have a total of 250 shades (250-0=250).

Unless you have very specific effects in mind, users are advised to leave this feature alone, so everything is always mapped to 255 shades (255-0). You can experiment with this feature to see what it does, however, and how it interacts with the input levels.

e Input edit boxes show how pixels are distributed over the 0-

to-255 pixel scale. The input values are related to the position of the indicators

along the histogram. For example, if you move the left triangle in from 0 to 30, the input range becomes 30 to 255, and pixels in the range of 0 to 30 are then set to 0. In a process called mapping, the new range (30 to 255) is stretched back to become 0 to 255. The image then becomes darker, since all pixels from 0 to 30 are now mapped to black (whereas 0 to 30 before had subtle gradations from black that lightened gradually).

f Input/Count/Percent figures provide information about the

• Count value indicates the number of pixels at the Input value. If

Input value is 2 and Count value is 1300, then there are 1300 pixels in the image at the input value of 2.

• Percent value is the percentage of all pixels in the image where

color value is less than or equal to the input value. If Percent is 15% and Input value is 2, it means that 15% of all pixels in the image have a value of 2 or less.

g The Channel button lets you control the Shadow and Highlight

settings for a particular color channel (red, green or blue) or for the Master channel (red, green, and blue simultaneously).

h The Original/Enhanced box lets you choose which histogram

to see: the original, before the image was modified; or enhanced, after the image had been modified (with shadows and highlights or any other tool).

How to read and correct a histogram

A histogram shows how the brightness and darkness levels are distributed in an image. The darkest pixels are at the left, and the lightest pixels are at the right.

An image with good contrast will have a histogram with vertical lines spread across the scale from left to right. Here, the histogram is heavily skewed to the left, where the darkest pixels are, indicating a dark image.

To change the histogram (and thus the image), use the three triangles below the histogram.

In the original histogram, the pixels are mostly to the left where the black triangle is, indicating a dark image. The range of spread is also broad and flat, with almost no pixels for the midtones and highlights where the gray and white triangles are.

In the corrected image, the triangles have been moved to new locations. The net effect is to narrow the distribution range of the pixels and lighten the image.

Generally, the best thing to do is to move the black and white triangles to the start and end of the curve.

Reference 3-65

For example, if your graph starts at about value 20 and ends at 240, then move the black triangle to 20 and the white triangle to 240. Move the gray triangle to somewhere in the middle between the black and white triangle.

• For grayscale scanners, only the gray channel is available.

2 Move the black, gray, and white triangles to change shadows,

midtones, and highlights, respectively. The values in the input edit boxes will change accordingly.

• To make the image darker, move in the black triangle to the

right.

• To make the image lighter, move in the white triangle to the

left.

• To change the midtones, move in the gray triangle. If the mid-

tone value is less than 1, the image becomes darker. If the midtone value is greater than 1, the image becomes lighter.

The x axis of the graph represents the original brightness values of the pixels, from 0 to 255; the y axis represents the new brightness values. Clicking on the diagonal line then plots a point that can be adjusted.

When the curve is moved up or down, the relationship between input value and output value changes accordingly.

• In areas where the curve is moved down, pixels in that por-

tion of the image are darkened.

• In areas where the curve is moved up, pixels in that portion of

the image are lightened.

Contrast in an image can be seen by the angle of the line. The steeper the slope, the higher the contrast. The closer the line is to horizontal, the lower the contrast.

Sample images and their curves

Here, the original curve is a straight diagonal, indicating that input and output values are equal.

Here, points along the curve have been moved up, so that pixels are lightened as they are plotted to new points.

The net effect creates a lighter image.

Here, points along the curve have been moved down, so that pixels are darkened as they are plotted to new points.

The net effect creates a darker image.

The Curve screen

Curve is a graphic representation of the gamma showing

scanner input from dark on the left to light on the right.

b Curve Buttons let you modify the curve. The tools are (left to

right) the pointer, zoom frame, and hand.

c Input/Output/Zoom:

• Input shows the input value of wherever the cursor is pointing

on the horizontal axis of the curve. In the example above, the cursor is pointing to the middle of the curve, with a value of 136 on the 0-to-255 pixel scale.

• Output shows the output value of of wherever the cursor is

pointing on the vertical axis of the curve. In the example above, the cursor is pointing to the exact middle of the curve, with a value of 119 on the 0-to-255 pixel scale.

• Zoom indicates the magnification level of the curve box. At

100% zoom, the curve is seen in its entirety. Using the zoom frame tool (discussed on page 3-72) to magnify the curve will zoom in or enlarge your view of the curve, resulting in a higher zoom percentage (ex. 200%).

d Channel allows you to choose the color or gray channel in

which the gamma will be affected.

Using the Curve buttons

The Curve buttons allow you to modify the curve in the Curve dialog box. The buttons are the Pointer, Zoom Frame, and Hand.

• Use the Pointer button to define points in the curve that will

be modified. When you click on any point in the curve, a control point appears to mark your position. To remove a control point, drag it off the graph.

New control points

• Use the Zoom Frame button to zoom in on a particular point

in the curve. Once the area is zoomed in, you can then use the pointer tool to define new points for more precision. This is particularly useful for working with 12-bit images, as more detail can be seen in such images. The zoom level can be seen in the Zoom column (item

c on page 3-71).

• Use the Hand button to scroll through the curve if the curve

has been zoomed in. The Hand tool can be used only if the curve has been zoomed in with the Zoom Frame button (above). Otherwise, the Hand tool will be dimmed.

How to use the Curve tool

Choose the channel in which the curve will be modified.

• Select Master to modify gamma in the red, green, and blue

color channels of the image simultaneously.

• Select color channels individually (red, green, blue) to modify

gamma in that particular color channel.

• For grayscale scanners, only the gray channel is available.

2 Choose the Method in which the curve will be modified; select

from Line, Curve, or Gamma. There is no difference in the method you select, and the choic-

es are provided to give you more flexibility in adjusting the curve.

3 Choose a curve button; select from Pointer, Zoom Frame, or

Hand. (See previous section Using a curve button for more details.)

4 Click on the curve to define the points where the curve will be

modified. You can then either raise or lower the curve at that point and see changes to the image accordingly.

5 Click on an action button.

• Click OK to accept changes and exit the AIE dialog box.

• Click Cancel to abandon all changes and exit the AIE dialog

box.

• Click Reset to restore settings to original default values.

• Click Revert to cancel the effect of the current image-enhance-

ment tool.

For more details, see the section The Action Buttons on page 3-34.

6 To save a curve, click on the Save button. A dialog box will

appear.

• Save the curve in either Polaroid or Photoshop format. The

Polaroid format allows you to have as many as 64 control points in the curve for more precision; Photoshop allows a maximum of 19.

• Choose the Channel. Select All if your channel (in #1) is

Master; select Current if you selected one of the three color channels (red, green or blue).

To use a previously saved gamma curve for another image, click on the Load button, then specify the curve to be loaded. Photoshop-saved curves can be loaded.
