Overview

Thank you for your purchase of a Nikon Scanner. This reference manual explains how to use Nikon Scan 2.0 for Windows, the scanner driver software provided with your film scanner for use with IBM PC/AT compatible computers running Windows 95 or Windows NT 4.0. Nikon Scan 2.0 for Windows functions as a thirty-two–bit TWAIN source, allowing you to scan images from your Nikon Film Scanner into TWAIN-compliant applications such as Adobe Photoshop version 4.0. It can also be used as a standalone scanning application for scanning images into your computer and saving them to disk.

Nikon Scan 2.0 supports scanning with the LS-2000 (SUPER COOLSCAN 2000). It allows non-sequential and batch scanning using the SA-20 strip-film adapter or IA-20 IX240 film adapter (sold separately). It also supports sequential scanning with the SF-200 slide-feeder adapter available for the LS-2000. Other features include:

• a scan window incorporating a wide variety of advanced setting options, making it possible to make fine adjustments to images before they are scanned

• a “defect correction” function that processes images digitally to remove dust and scratches during scanning

• support of grayscale, RGB (sRGB), HSL, and CMYK color models, producing images suited to a wide variety of uses

• advanced settings such as gamma curve adjustment and hue editing that allow precise adjustment of images prior to scanning

This reference manual describes how to install and use Nikon Scan 2.0 for Windows. The next chapter, “Before You Begin,” lists the system requirements for Nikon Scan and takes you step-by-step through the installation process. For a quick guide to installation, refer to the User’s Guide. “Before You Begin” is followed by “Basic Operations,” which describes the steps in- volved in starting Nikon Scan, adjusting scan settings, scanning images, and saving images to disk. “The Scan Window” introduces you to Nikon Scan’s TWAIN source, or scan, window and explains scan window preferences. In “The Thumbnail Drawer,” Nikon Scan’s thumbnail display, used when previewing multi-frame film on the LS-2000, is described. The process of selecting the portion of an image to be scanned and adjusting scan settings prior to scanning is detailed in “Preview,” “The Size

Drawer,” “The Curves and Levels Drawer,” and “The Color Balance Drawer,” while ”Saving and Loading Settings” describes how

changes to settings can be saved for later use. The final chapter, “Image Window Operations,” describes the options available when Nikon Scan is used as a stand-alone application. The settings available for each scanner are described in separate appendices.

The Gamma tab

The Gamma tab in the Preferences dialog allows the user to set the output gamma values used in displaying preview images and in making the final scan.

Preview gamma

Gamma compensation for the scan window can be set by direct input or using the slider. Adjust the gamma value so that the gray patterns above the gamma slider match in density. When performing this adjustment, it is best if you set the resolution of

the monitor to a low value such as 640 × 480 dots and sit as far

away from the monitor as possible. To restore the factory default gamma value of 2.2, click the reset button.

Main scan gamma

Main scan gamma is used when the image in the scan window is scanned and passed to the host application (if you are using Nikon Scan as a “stand-alone” application, preview gamma will be used when the image is scanned; hence the main scan area will not appear in the Gamma tab). The gamma value used in the final scan can be chosen from the following options:

use preview gamma

The gamma value for the final scan will be the same as that shown in the preview gamma text box.

Note: If you are using the Nikon Color Management System, you can specify that the gamma values set in the Gamma tab not be used. See “The Color Management tab,” below.

The Color Management tab

Nikon Scan’s Color Management System (CMS) allows you to select calibrated RGB (sRGB), CMYK, and HSL color models as the color space for displaying and modifying images prior to scanning. You can adjust Nikon Color Management settings using the Color Management tab in the Preferences dialog.

If the “use Nikon Color Management System” check-box in the top of Color Management tab is on (the default setting), the Nikon Color Management System will be used. When CMS is on, the user can choose from sRGB (calibrated RGB ), CMYK, and HSL color spaces. When off, only RGB and grayscale color spaces are available. To put changes to Color Management settings into effect, click the OK button to close the Preferences dialog, then exit and restart Nikon Scan.

Output color space

The color space used when the image is scanned and passed to the host application depends on whether Nikon Color Management is used. When CMS is used and Nikon Scan is being used as a TWAIN source, the color space chosen in the scan window color-space pop-up menu (sRGB, CMYK, or HSL) is used in the scan window only; when scanned, the image is passed to the host application as RGB data. When Nikon Scan is being used as a “stand-alone” application, the color space does not change when the image is scanned. If CMS is not used, the scanned images will be passed to the host application using the color space specified in the scan window (RGB or grayscale).

Batch scan

Some scanners, such as the LS-2000, can automatically scan several frames of strip film or IX240 film in succession. Depending on the scanner, multiple images can also be scanned automatically using a slide-feeder. If such a device is selected, the scanner can be set to stop scanning after an error has occurred by turning batch scan stops on error check-box off (by default, the scanner will not stop scanning even when an error has occurred).

Close thumbnails after preview

By default, the thumbnail drawer remains open after a preview scan is performed. If the close thumbnails after preview check-box is on, the thumbnail drawer will close automatically after a preview has been performed.

The Thumbnail Drawer

When a scanner that supports non-sequential scanning of multiimage media such as strip film or IX240 film is selected, the scan window’s thumbnail drawer-tab will be activated. Using the thumbnail drawer, all images in the film can be previewed as thumbnail images and one or more selected for full-scale preview or scanning.

Opening the Thumbnail Drawer

Click the thumbnail drawer-tab in the control area of the scan window to open the thumbnail drawer.

Thumbnail drawer-tab

The thumbnail drawer can be closed by clicking the box at its upper right corner.

Note: Nikon Scan’s thumbnail function is only available when the scanner currently selected allows non-sequential access to multiple images. Non-sequential access is supported on the LS-2000 when SA-20 strip film adapter or the IA-20 IX240 film adapter are inserted. When the strip film adapter is connected, two to six thumbnails will be displayed depending on the number of frames in the strip. Depending on the film used, fifteen, twenty-five, or forty thumbnails will be shown when the IX240 adapter is in place. If the current scanner or adapter does not support non-sequential access, no thumbnail drawer-tab will be displayed.

In this mode, small preview images, or “thumbnails,” of all frames will be displayed in the thumbnail drawer. By default, thumbnail previews will automatically be created and displayed when the thumbnail drawer is opened.

Hide thumbnails button

Clicking the “Hide thumbnails” button in the thumbnail drawer when thumbnails are displayed will replace the thumbnails with a frame-number display.

In this mode, frame numbers are displayed in place of thumbnail previews. The thumbnails will however be stored in memory, making it possible to return instantly to a thumbnail display by clicking the “Display thumbnails” button a second time. The thumbnail images will be kept until the scan window is closed or film ejected.

Display thumbnails button

Note: If in the Miscellaneous tab of the Preferences dialog the “always acquire thumbnails” check-box is on (the default setting), thumbnails will be created the first time the thumbnail drawer is opened. As a result, it may take some time for the drawer to open the first time the drawer-tab is clicked. If you prefer, you can select the frame-number display. In this case, thumbnail images are only created when the “Display thumbnails” button is clicked. Note however that the LS-2000’s SA-20 strip-film adapter adjusts frame settings when creating thumbnails. If you conduct a preview scan without first creating thumbnails, the borders of the frames may be slightly out of position when the image is previewed or scanned.

Scanning multiple frames simultaneously

Selecting multiple thumbnails

Multiple frames can be selected for scanning by holding down the ctrl key while clicking each frame in turn. Frames already selected can be deselected by clicking them a second time. When a frame is selected, clicking another frame with the shift key held down will select all frames between the two. Flip and rotate operations apply simultaneously to all selected thumbnails.

Scanning multiple thumbnails

Preview or scan operations can be performed on multiple selected frames. When the preview button is clicked, a preview scan will be performed one at a time on the selected frames and the resulting preview images stored temporarily in memory. When any of the previewed thumbnails is subsequently selected in the thumbnail drawer, the preview for that image will be displayed in the preview/crop area. You can switch among the images in memory by clicking the thumbnails of the previewed images. Crops and scan settings can be specified separately for each preview. When the scan button is clicked, a full scan will be performed on all the frames currently in memory using the scan settings and crops for each frame. The scanned images will be opened in separate windows in the host application or in Nikon Scan’s main window.

If the scan button is clicked when multiple frames are selected in the thumbnail drawer, the images will be scanned and transferred to the host application one at a time. If Nikon Scan is functioning as a “stand-alone” application, the scanned images will be opened in separate image windows.

Preview

Before an image is scanned into another application or into image windows in Nikon Scan, it can be previewed in the scan window. This chapter describes the basic operations that can be performed prior to scanning, such as rotating and flipping the image, adjusting contrast and focus, and selecting an area for the final scan. Other adjustments that can be made using the drawer tab controls are discussed in the chapters for each drawer.

Film Type and Color Space Selection

Film-type menu button

Before previewing an image, it is necessary to specify the type of film used in the scanner and to select the “color space” into which the images are to be scanned.

Specifying the film type

The type of film to be scanned is set using the film-type pop-up menu in the scan window’s control area.

To specify the film type, click the film-type menu button and from the menu that appears select the type of film to be scanned (note that the contents of this menu may vary depending on the scanner selected). The current film type will be displayed in the menu button.

Choosing a Color Space

When scanning images with Nikon Scan, you must choose a “color space,” i.e., the color model that will be used in convert- ing the original, analog image into digital form for transfer to your computer. This chapter explains the color spaces available in Nikon Scan and how to change the color space setting.

Clicking the color-space menu button in the scan window’s control area displays the color-space pop-up menu shown below. Choose the desired color space from the menu. The selected space will be displayed in the menu button.

Color-space menu button

Color space can be selected from among the following color models. The default setting is sRGB (calibrated RGB).

sRGB RGB is the model used in displaying images

on a computer monitor. Colors are represented using different intensities of the three primary colors, red, green, and blue. Nikon Scan actually uses calibrated RGB, or sRGB.

CMYK Colors in the CMYK color model are repre-

sented using combinations of the four colors commonly used in printing (cyan, magenta, yellow, and black).

HSL Colors in HSL are represented using hue,

saturation, and luminosity. Nikon Scan uses a calibrated HSL color model.

The selected color space is used for making adjustments to color balance and tone range in the preview window. If Nikon Scan is being used as a “stand-alone” application, the color space will be preserved when the image is scanned. When Nikon Scan functions as a TWAIN source for another application, however, the scanned image will be converted to RGB before being transferred to the host application.

Selecting a Crop

When an image is previewed in the scan window, you can select the area that will be scanned during the final scan. The part of the image that will be scanned is called a “crop.” This section discusses how to select a new crop and how to change the size and position of the current crop (the size of the crop can also be set through direct input, as discussed in “The Scan Size Drawer,” below).

Making a new crop

To select a crop, move the mouse pointer over the image in the preview/crop area, then click at one corner of the desired area and drag the cursor to the opposite corner. The area selected will be marked by a frame. The current crop can be cancelled by creating another crop or by double-clicking in the

Preview: Selecting a Crop

Note: When output lock is selected in the scan-size drawer (see “The Scan Size Drawer,” below), the crop sometimes can not be enlarged to the same size as the original image by double-clicking in the current crop. In this case, you will need to open the scansize drawer and click the input-lock button to release output lock.

- 59 -

Moving the crop area

The crop frame can be moved to a new location simply by placing the cursor within the frame and dragging it to a new position.

Note: “Dragging” means moving the mouse while holding down

the mouse button.

Changing the size of the crop area

To change the size of the crop area, drag a side or corner of the crop frame. Dragging a side will change the size of the area in only one dimension, while dragging a corner allows you to change both height and width simultaneously.

Note: When output lock is selected in the scan-size drawer (see “The Scan Size Drawer,” below), the width-height aspect ratio of the current crop can not be changed by dragging the crop borders. To release output lock, open the scan-size drawer and click the input-lock button.

Note: For reasons relating to the compression and display of the

preview image, there may be a slight difference between the crop area specified on the screen and the area that is actually scanned. When cropping an image, always allow a sufficient margin to ensure that no important element of the image will be inadvertently cropped out.

Automatic Contrast Adjustment

Contrast can be adjusted automatically to suit the image in the preview/crop area, creating a more clearly-defined image (contrast can also be adjusted manually, as described in “The Curves and Levels Drawer,” below). When a preview image is displayed in the scan window, the auto contrast button (labeled cont) will be activated. Click this button to maximize contrast while retaining the color balance of the original image.

Auto contrast button

While auto contrast is in effect, the button will be highlighted in red.

Note: Auto contrast is only available when the color space is RGB, sRGB, CMYK, or grayscale. The auto contrast button has the same effect as the auto button in the curves-and-levels drawer (see “The Curves and Levels Drawer,” below). While auto contrast is in effect, the tone curves for each color channel will be automatically adjusted to increase contrast. The original contrast can be restored by clicking the reset button in the curves-andlevels drawer while holding down the ctrl key on the keyboard.

The Pixel Data Display

When the cursor is moved over the image in the preview area, color data for the pixel under the cursor are shown in the pixel data display.

Pixel data display

How the pixel data are displayed depends on the currently selected color space. Numerical data will be displayed separately for each color element (e.g., red, green, and blue for an RGB color space, hue, saturation, and luminosity for an HSL color space). The displays for the sRGB (or RGB) and CMYK color spaces are shown below. If output levels have been edited in the curves-and-levels or color-balance drawers (see “The Curves and Levels Drawer” and “The Color Balance Drawer,” below), two sets of data will be displayed. The top line gives the pixel data for the original image, the bottom for the image as it would appear after scanning.

Autofocus

The autofocus function adjusts scanner focus to compensate for films of varying thicknesses and for uneven film surfaces. The focus position for the autofocus operation can be changed using the “autofocus” button in the control area of the scan window.

Nikon Scan allows the user to choose from the following two methods for determining focus: standard autofocus and autofocus based on a user-selected point. The default is standard autofocus, in which focus is determined using a point in the center of the preview image. To use standard autofocus, click the autofocus button.

Autofocus button

Note: Using the Miscellaneous tab in the Preferences dialog, it is possible to set the scanner to perform an autofocus operation automatically before making the final scan ( see “The Scan Win- dow: Preferences,” above).

User-selected focus

To change the focus position, hold down the ctrl key on the keyboard and click the autofocus button. The cursor will take the shape of a cross. Move the cross-shaped cursor over the point in the preview image that you want to use as the new focus point and click. An autofocus operation will be performed using the selected point as the focus position, and the result of this operation will be used in subsequent scans.

Note: When a scanner that does not support autofocus is selected, the autofocus button will be grayed out and inactive. If the scanner does not support user-selected autofocus, only standard autofocus can be used.

The lower portion contains output size controls, which determine the final size of the image after it is scanned. Output size controls include the following:

• a file size display giving the size of the file that would result were the current crop to be scanned at the stated output settings

• an output lock button, which locks output dimensions and file size at their current values

• an output-units pop-up menu, from which the units used for stating output dimensions can be chosen

• output resolution and pop-up menu for output resolution units

• a device pop-up menu, from which the user can choose an output resolution suited to a particular output device

Using these controls, the user can select an output resolution and specify the dimensions and file size of the image to be scanned.

Input size

The input portion of the scan-size drawer gives the height (H) and width (W) of the current crop, which are the actual physical dimensions of the portion of the medium to be scanned. New values for crop size can not be entered in the input size text-boxes, but the size of the crop can be changed by dragging the borders of the crop in the preview/crop area.

Output size

The output size determines the size of the image after it is scanned into the calling application. The output size can be changed either by adjusting the size of the crop in the preview area, or by entering values directly into the boxes in the output size area. Unacceptable values will be displayed in red. The size of the current crop is linked to the output size, and changes when new values are entered in the output height and width boxes.

File size

Output resolution

The file size display shows the size (in bytes, kilobytes, or megabytes) of the image that would be created were the current crop to be scanned at the current output size and resolution.

It is a good idea to check the file size value before starting a scan.

Scale

“Scale” expresses the relationship between the input size and the output size. If the scale is two-hundred percent, a crop fifty pixels by fifty pixels in size would be passed to the host application as an image of 100 by 100 pixels after scanning.

Scale can be set by dragging the scale slider or entering a value directly in the text box. Unacceptable values will be displayed in red. The input size remains constant when the scale is changed, while the output size changes to match the new setting.

The output resolution is the resolution of the image that will result when the current crop is scanned. The resolution chosen should reflect how the image is to be used; if the image is ultimately intended to be displayed on a printer with a resolution of 720 dpi, for example, setting the output resolution to 1,350 dpi would create an unnecessarily large file. Enter the desired resolution in the resolution field. Unacceptable values will be shown in red.

The units for resolution can be selected from the pop-up menu to the right of the resolution field.

Resolution can be set to a value that matches the standard resolution of a specific output device, such as the computer’s monitor or the currently selected printer. To set resolution to a value that corresponds to the resolution of an output device, choose the desired device from the pop-up menu at the bottom of the scan-size drawer. The devices that will be displayed in this menu depend on what devices are registered on your system.

Input and Output Lock

The scan size drawer contains two lock buttons: an input lock button and an output lock button. One or the other of the lock buttons is always in effect.

Input lock

The input button locks the height and width of the current input crop so that when one of these dimensions is changed by entering a new value in the output size area, the other changes to maintain a constant height-width aspect ratio. When clicked, the button is highlighted in blue. When a new value is entered for either height or width in the output size area, the other dimension will change automatically to maintain the crop at its current proportions. This lock affects only the scan size drawer; the size and position of the current crop can be freely altered in the preview/crop area using the mouse, in which case the height-width aspect ratio in the scan size drawer will be locked at the proportions of the new crop. To unlock the aspect ratio, click the output button.

Output lock

The output button locks the output dimensions and file size at their current values. When clicked, the button is highlighted in blue. Even when the sides of the current crop in the preview/ crop area are dragged to re-size the crop, the output dimensions will not change. Instead, the scale will change to maintain the output dimensions and file size at their current values. When the crop is enlarged, the scale will decrease to keep the output dimensions the same; similarly, shrinking the crop will cause the scale to increase. The crop cannot be enlarged or reduced beyond the acceptable limits for scale. When output lock is in effect, the output dimensions in the output size area of the scan size drawer can still be changed by direct input, in which case the scale will not change. To unlock the output dimensions and file size, click the input button.

The Curves and Levels Drawer

Nikon Scan provides two means of color control: direct manipulation of the gamma curves via the curves-and-levels drawer, and basic color balance adjustment by means of the sliders in the color-balance drawer. This chapter describes the tools available in the curves-and-levels drawer in the scan window. Color balance is described in the following chapter.

The curves-and-levels drawer is used to modify the contrast and brightness for the various color elements (“channels”) in the output by adjusting the gamma curves and levels either for the image as a whole or for each color element separately. In many cases, the factory default gamma curves, which are designed to handle the widest possible variety of film, will produce images with excellent color. In some cases, however, you may wish to adjust the gamma curves prior to scanning. The color-balance drawer provides a simple method of making this adjustment, but the curves and levels drawer offers more selective control.

Curves and Levels Explained

The curves and levels drawer contains two tools for altering the gamma curves and levels: gamma curve adjustment and black point/white point adjustment. Gamma curves are plotted on two axes, one representing the input, i.e., the colors present in the actual image, and the other the output, which expresses how the colors in the input will be represented in the final scan.

At one end of each axis is the minimum possible value for the color (zero, or no color) and at the other is the maximum value (the maximum value depends on the scanner’s bit depth; if the image is to be scanned at a bit depth of eight bits per pixel, the maximum value will be 255). The gamma curve determines how the input values will be converted, or “mapped,” to output values. The default mapping is one-to-one, so that input values of zero are output as zero, while input values of 255 are represented as 255 in the output.

By altering the gamma curves, it is possible to change the mapping between input and output colors at any point on the curve. Thus input values of zero could be mapped to a value of 255 in the output, and input values of 255 to a value of zero. If the curve between these two points were a straight line, the result would be a negative image. In practice, smaller adjustments are made to enhance the tonal range for specific portions of the image, such as shadows, mid-tones, and highlights. Steepening the slope in a small portion of the curve will accentuate detail in that part of the tonal range, allowing color balance and definition to be selectively adjusted.

The Curves and Levels Drawer: Curves and Levels Explained

Black- and white- point adjustment allow the user to adjust the range for each color element, in effect adjusting contrast. The black point for a given color represents the darkest shade, or minimum value for that color in the image. By default, this value is zero. The minimum value in the actual input may however be greater than zero, with the result that the portion of the scanner’s tonal range between zero and the actual minimum is wasted. Using black point adjustment, it is possible to map the actual minimum input value to an output value of zero, thus matching the range of colors in the output to the range available in the input. Similarly, white point adjustment can be used to map the maximum value actually present in the input to the maximum possible output value, eliminating all values greater than the maximum input value and making the best use of the scanner’s tonal range.

The curves-and-levels drawer offers the following four methods for adjusting gamma curves and levels:

• automatic white point and black point selection

• pixel sampling to determine the white point and black point

• simple gamma curve adjustment using a slider

• fine gamma curve adjustment by adding and moving points on the curve

Opening the Curves and Levels Drawer

The Curves and Levels Display

The curves and levels display for an RGB color-space is shown below. The displays for grayscale and CMYK color-spaces are similar; the display for a color space of HSL is unique and is discussed in the final section of this chapter.

Channel menu

button

A histogram of the current channel is displayed as a bar graph in the background of the gamma curve window. The histogram’s horizontal axis represents the pixel intensity, the high density (darker) values appearing on the left and the transparent (lighter) density values on the right. The vertical axis represents a scaled version of the number of occurrences of each pixel value. The histogram therefore gives a graphical view of the brightness of an image.

Channel selection

Gamma curve

window

The gamma curve window in the curves and levels tab shows the gamma curve for the currently selected color element, or “channel.” The illustration above shows the default gamma curve, which runs diagonally from the lower left corner of the window to the upper right. The input value is plotted on the horizontal axis, the output value on the vertical. Thus the left edge of the gamma curve window corresponds to an input value of zero, the right edge to the maximum possible input value for the current channel, while the bottom and top of the window show respectively the minimum and maximum output values.

The Curves and Levels Drawer: The Curves and Levels Display

The gamma curve and histogram for each channel can be displayed using the channel pop-up menu. Select the desired channel from channel pop-up menu for the current color space, which can be displayed by clicking the channel menu button. The current channel is shown in the menu button. The items available in the channel menu vary depending on the

color space. Each color space has a master channel, which allows adjustments that affect all the color elements in the image, and a separate channel for each of the color elements in the space. The menus for the sRGB (or RGB) and CMYK color-spaces are shown below.

RGB channel pop-up menu CMYK channel pop-up menu

- 77 -

The grayscale color space is composed of a single color element and hence has only one gamma curve. When the selected color space is “grayscale,” the channel menu button will not be shown in the curves and levels drawer.

The input/output value display

When the cursor is moved over the gamma curve window, the horizontal (input) and vertical (output) coordinates of the point under the cursor are shown in the input/output value display. The range of values shown is 0–255, independent of scanner bit depth (the actual scanner bit depth is however used in internal calculations involving the gamma curves).

Output/input value display

When the cursor is over the image in the preview/crop area, a point on the gamma curve corresponding to the value of the pixel under the cursor will be highlighted. The input value will show the actual value of the pixel, the output value the value of the pixel after the mapping function represented by the gamma curve has been applied.

Gamma Curve Adjustment

The gamma curve for each channel can be adjusted either using the gamma slider, which raises or lowers output levels for the curve as a whole, or by adding additional points to the curve to make more precise adjustments to output levels.

Using the gamma slider

Output levels can be raised or lowered for the entire gamma curve using the gamma slider at the bottom of the gamma curve window. The slider can be activated by clicking it once.

The gamma value input box

The gamma value displayed in the gamma input box to the right of the gamma curve window is linked to the gamma slider, increasing as the slider is moved to the left and decreasing as it is moved to the right. If desired, the gamma curve can be set by entering a value between 0.45 and 3.00 in the input box.

Reset button

Gamma slider

Moving the slider to the left increases all the output values for the selected channel, while the output values will decrease when the slider is moved to the right. The gamma curve will be altered to reflect the new values, and the preview image in the scan window will change to show the effects of the new values.

The Curves and Levels Drawer: Gamma Curve Adjustment

Undoing changes

Clicking the reset button will return the gamma curve for the current channel to linear (equivalent to a gamma value of 1.00). Clicking reset with the ctrl key held down resets the gamma curves for all channels to linear.

Graphically altering the gamma curves

For finer adjustments to output levels, points can be added to the gamma curve by clicking anywhere in the gamma curve window. These points can be freely adjusted by dragging them to the desired position, changing the shape of the gamma curve.

Adding new points to the gamma curve

Move the cursor into the gamma curve window and click once anywhere within the window to enter gamma curve edit mode. Move the cursor to the place you would like to add a new point, then click. A new point will appear at this position and the curve automatically adjusted to pass through this point. To move the new point, place the cursor over the point. The new points can be moved by dragging them in the gamma curve window to change the shape of curve. The preview image in the scan window will be altered automatically to reflect changes to the gamma curve.

Removing points from the gamma curve

Points can be removed from the gamma curve by dragging them out of the gamma curve window.

Undoing changes

Clicking the reset button will restore the gamma curve for the current channel to linear, removing all points but those on either end of the curve. Clicking reset with the ctrl key held down resets the gamma curves for all channels to linear.

Adjusting the Black and White Points

The left end of the gamma curve for a given channel represents the “black point” for that channel, the right end the “white point.” Moving the black point to the right results in all input values less than the black point being mapped to an output value of zero. Moving the white point to the left results in all input values greater than the white point being mapped to the maximum output value. These tools can be used to adjust the gamma curve to remove values not available in the input, making better use of the scanner’s dynamic range and increasing contrast.

Nikon Scan offers three methods for adjusting the white and black points. The white and black points can be set automatically, or adjusted manually using the sliders in the gamma curve window. The preview image can also be sampled directly to select a white or black point from the values actually visible in the original film.

Automatic contrast adjustment

Nikon Scan can, if desired, analyze the preview image and select optimum black and white points for the selected channel. To perform automatic contrast adjustment, click the auto button in the curves and levels drawer. The end points of the selected curve will be adjusted to optimize the dynamic range for the entire crop.

Auto contrast button

Reset button

To cancel automatic contrast and return the gamma curve to linear, click the reset button. If the ctrl key on the keyboard is held down when the reset button is clicked, the gamma curves for all channels will be reset to linear.

Note: The effect of the auto button in the curves-and-levels drawer differs from that of the contrast button in the control area. The contrast button in the control area affects not just the currently selected channel but also the master channel, adjusting contrast for all color channels simultaneously. Note that this may sometimes lead to undesirable color balance. If for example, the original image is of a predominantly “warm toned” scene, such as a sunset, then the neutral highlight produced by automatic contrast adjustment would be too “cold” for the image.

Using the black-point and white-point sliders

The black- and white-points can also set directly for each channel using the sliders at the bottom of the gamma curve window. While the sliders can be used to edit the curves for any channel, in most cases the best results can be obtained when they are used to modify the master curve.

The black-point slider

Click the black-point slider once to activate it, then drag it to the right or left to set the new black point. All pixels in the input with a value less than the black point will be mapped to an output value of zero. This can be used to eliminate points from the curve that are not represented in the input, enhancing contrast, or to adjust brightness. If a histogram is displayed in the gamma curve window, the black point can be set to the lowest available input value by matching the slider with the leftmost bar in the histogram. The effects of the new black point can be ascertained by observing the adjusted automatically to match changes

Setting the black and white points by sampling

The black and white points can be set by directly sampling the pixels in the preview area. This provides a means of matching the black and white points to the minimum and maximum values actually visible in the original film. Direct sampling can be used to set the end points of the gamma curve for any channel, but is most effective when used with the master channel.

Sampling the black point

To set the black point, or minimum input value, select the desired color channel and then click the black-point button ( ). When the button is clicked, the cursor will become an eye-dropper when moved over the image in the preview/crop area.

Move the cursor to the point to be used as the darkest in the image. You may wish to close the curves and levels drawer so that you can view the pixel data display to determine which area of the image is the darkest for the color or colors in the current color channel. The darkest point in the image will have the lowest pixel values for that color. With the cursor over the point that is to serve as the darkest in the image, click the mouse button. The selected point will be the new black point, or reference point for darkness. The cursor will return to its previous shape, and the preview image will automatically be altered to reflect the new black point.

Note: Sampling the black point does not change the master curve. If the master channel is selected when the black point is sampled, the black point for each individual color channel (e.g., the channels for red, green, and blue in the case of RGB) will be altered to match the input value for that color at the pixel sampled, but the black point for the master channel will remain unaltered. The new black points for the remaining color channels can be viewed by holding down the histogram button ( ).

Note: The black-point button is only active when a preview image is displayed in the preview/crop area.

Sampling the white point

To set the white point, or maximum input value, select the desired color channel and then click the white-point button ( ). When the button is clicked, the cursor will become an eye-dropper when moved over the image in the preview/crop area.

Move the cursor to the point to be used as the brightest in the image. You may wish to close the curves and levels drawer so that you can view the pixel data display to determine which area of the image is the brightest for the current color channel. The brightest point in the image will have the highest pixel values for the color or colors in the current channel. With the cursor over the point that is to serve as the brightest point in the image, click the mouse button. The selected point will be the new white point, or reference point for brightness. The cursor will return to its previous shape, and the preview image will automatically be altered to reflect the new white point.

HSL Controls

Using the saturation slider

When the selected color space is HSL, gamma curves will not be displayed in the curves and levels drawer. Instead, HSL controls appear, making it possible to determine how input hue, saturation, and luminance will be altered when the image is scanned.

Channel menu button

Saturation slider

The HSL controls consist of a saturation slider and separate channels for luminance and hue. The following channel pop-up menu will appear when the channel menu button is clicked. The appearance of the drawer will vary depending on whether luminance or hue is selected.

The saturation slider appears in the displays for both the luminance and hue channels. Its function is equivalent to that of the gamma slider in the RGB, CMYK, and grayscale gamma windows. Raising the slider increases saturation and decreases the gamma value, creating a preview image with deeper colors, while lowering the slider increases the gamma value, lightening the colors in the image. The center of the scale is equivalent to a gamma value of 1.00

Editing the hue channel

When the hue channel is selected from the channel pop-up menu, the curves-and-levels drawer takes on the appearance shown below. The controls for editing hue are unique, consisting of a horizontal line crossing a rainbow-colored background. The input values for each hue (color) are plotted along a straight line running through the center of the editing window. Points on the control line can be raised or lowered to map the input color to a new output color.

The width slider

When a point on the control curve is moved, the control curve will be altered to pass through the new point using a simple bell-shaped curve to join the new point to the center line. The width of the bell curve can be adjusted using the width slider. These hue controls provide an extremely powerful editing function which allows the user to change the mapping for a specific color without affecting other colors in the image. To determine the color of a specific pixel, move the cursor over the preview image in the scan window. A point on the input line corresponding to the color of the pixel under the cursor will be highlighted in the curves and levels edit window.

The luminance controls are similar to the gamma, black-point, and white-point slider controls discussed in the preceding sections, consisting of a luminance slider, which controls the main luminance curve, and sliders to set the minimum and maximum values for input luminance. The luminance curve-editing window also contains a histogram. The horizontal axis of the histogram gives the value for luminance, with minimum luminance on the left and maximum luminance on the right.

Moving the luminance-curve slider to the left increases output luminance, making the image brighter, while moving the slider to the right decreases output luminance, creating a darker image. The effects of the luminance slider can be determined by viewing the image in the preview/crop area.

The sliders for maximum and minimum luminance can be used to adjust output luminance to match the range of values actually present in the input, so making best use of the scanner’s dynamic range. The minimum input-luminance slider sets the minimum value for input luminance. All pixels in the input image that have values less than the minimum are converted to a value of zero (black) when scanned. The minimum value increases when the slider is moved to the right and decreases when the slider is moved to the left. The minimum inputluminance value can be matched with the lowest value actually present in the input image by matching the slider with the leftmost bar in the histogram. The luminance value for a specific pixel in the input image can also be determined by moving the cursor over the preview image in the scan window.

Contrast

When the color space is sRGB or RGB, the color balance tab will contain the controls shown below. When the color space is grayscale, only the brightness and contrast sliders will be active.

Brightness, contrast, and color balance can be set by dragging the sliders to the right or left. Any changes made in the color balance drawer will be reflected immediately in the preview image in the scan window.

Brightness

The brightness slider adjusts brightness for the entire image. Dragging the brightness slider to the right brightens all the colors in the image, making the image as a whole more white. Dragging the slider to the left darkens all the colors in the image, making the image as a whole darker and less distinct.

Dragging the contrast slider to the right heightens the difference between highlights and shadows in the image, increasing contrast. Dragging the slider to the left decreases the difference between light and dark portions of the image, making the images flat and dull.

Color balance

While the brightness slider adjusts brightness for the image as a whole, the three color balance controls allow the user to adjust brightness for each color individually. For example, dragging the red slider to the right brightens the red portions of the image, making the image as a whole more red. Dragging it to the left dims the red elements in the image, bringing out the remaining colors.

Note: The brightness and color sliders have the same function as the gamma slider (brightness corresponds to the slider for the master curve, the color sliders to the curves for each color element). When contrast is increased with the contrast slider, the effect is the same as if the white- and black- points were moved toward one another, steepening the master gamma curve. The two drawers however function however independently of one another; hence changes in one drawer are not reflected in the other. If separate adjustments are made in each drawer, the changes will be merged when the image is scanned.

Exporting and Importing Settings

Importing settings

You can save the current scan window settings to a file using Export Settings…. Unlike Save Settings…, which saves settings in a system file that can only be accessed by Nikon Scan

2.0, Export Settings… saves settings to independent files. These files can be read using Import Settings…. It is recommended that Export Settings… be used to store settings in a location separate from Nikon Scan, for example in the same folder as the images scanned at the saved settings.

Exporting settings

When Export Settings… is chosen from the settings menu, the standard save file dialog will appear. After specifying the drive and folder to which the settings are to be saved and entering a file name for the settings, click the Save button to save the settings under the specified name.

Settings saved with Export Settings… can be read using the Import Settings… command.

When Import Settings… is chosen from the settings menu, the standard open file dialog will appear. Choose the drive and folder containing the settings to be read and select the desired file, then click the Open button to load the specified settings into Nikon Scan.

When a settings file is read into Nikon Scan, the preview image in the scan window will disappear.

Image Window Operations

The Main Window

When Nikon Scan 2.0 is used as a stand-alone application, images will be opened in Nikon Scan’s main window after scanning. The main window is a small-scale application that allows the user to flip and rotate images after scanning, save images to disk in a variety of file formats, open previously saved image files, and print images. This chapter describes the main window and its functions.

Note: When Nikon Scan 2.0 is being used as a TWAIN source for another application, such as Adobe Photoshop, rather than as a stand-alone application, images will be opened in the host application. Refer to the application’s manual for details on post-scan image editing.

When Nikon Scan 2.0 is used as a stand-alone application, scanned images will be opened in image windows within the main window, where they can be viewed, modified, printed, or saved. The operations that can be performed in image windows are carried out using the menus and tool bar in the main window.
