Chapter 2: Workspace

The Adobe® Photoshop® CS3workspace is arranged to help you focus on creating and editing images. Theworkspace includes menus and a variety of tools and palettes for viewing, editing, and adding elements to your images.

Workspace basics

Workspace overview

You create and manipulate your documents and files using various elements such as panels, bars, and windows. Any arrangement of these elements is called a workspace.WhenyoufirststartanAdobeCreativeSuitecomponent,you see the default workspace, which you can customize for the tasks you perform there. For instance, you cancreate one workspace for editing and another for viewing, save them, and switch between them as you work.
You can restore the default workspace at any time by choosing the default option on the Window > Workspace menu.
14
Although default workspaces vary across Flash, Illustrator, InCopy, InDesign, and Photoshop, you manipulate the elements much the same way in all of them. The Photoshop default workspace is typical:
The menu bar across the top organizes commands under menus.
The Tools panel (called the Tools palette in Photoshop) contains tools for creating and editing images, artwork,
page elements, and so on. Related tools are grouped together.
The Control panel (called the options bar in Photoshop) displays options for the currently selected tool. (Flash has
no Control panel.)
The Document window (called the Stage in Flash) displays the file you’re working on.
Panels (called palettes in Photoshop) help you monitor and modify your work. Examples include the Timeline in
Flash and the Layers palette in Photoshop. Certain panels are displayed by default, but you can add any panel by selecting it from the Window menu.Many panels have menus with panel-specific options. Panels can be grouped, stacked, or docked.

Dock and undock panels
A dock is a collection of panels or panel groups displayed together, generally in a vertical orientation. You dock and undock panels by moving them into and out of a dock.
Note: Docking is not the same as stacking. A stack is a collection of free-floating panels or panel groups, joined top to bottom.
To dock a panel, drag it by its tab into the dock, at the top, bottom, or in between other panels.
To dock a panel group, drag it by its title bar (the solid empty bar above the tabs) into the dock.
To remove a panel or panel group, drag it out of the dock by its tab or title bar. You can drag it into another dock
or make it free-floating.

To prevent panels from filling all space in a dock, drag the bottom edge of the dock up so it no longer meets the edge of the workspace.
Move panels
As you move panels, you see blue highlighted drop zones,areaswhereyoucanmovethepanel.Forexample,youcan moveapanelupordowninadockbydraggingittothenarrowbluedropzoneaboveorbelowanotherpanel.Ifyou drag to an area that is not a drop zone, the panel floats freely in the workspace.
To move a panel, drag it by its tab.
To move a panel group or a stack of free-floating panels, drag the title bar.
Press Ctrl (Windows) or Control (Mac OS) while moving a panel to prevent it from docking.
Add and remove docks and panels
If you remove all panels from a dock, the dock disappears. You can create new docks by moving panelsto drop zones next to existing docks or at the edges of the workspace.
To remove apanel, click its close icon (the X at the upper-right corner of the tab), or deselect it from the Window menu.
To add a panel, select it from the Window menu and dock it wherever you wish.
Manipulate panel groups
To move a panel into a group, drag the panel’s tab to the highlighted drop zone at the top of the group.
PHOTOSHOP CS3
User Guide
Adding a panel to a panel group
To rearrange panels in a group, drag a panel’s tab to a new location in the group.
To remove a panel from a group so that it floats freely, drag the panel by its tab outside the group.
To make a panel appear at the front of its group, click its tab.
To move grouped panels together, drag their title bar (above the tabs).
Stack free-floating panels
When you drag a panel out of its dock but not into a drop zone, the panel floats freely, allowing you to position it anywhere in the workspace. Panels may also float in the workspace when first selected from the Window menu. You can stack free-floating panels or panel groups together so that they move as a unit when you drag the topmost title bar. (Panels that are part of a dock cannot be stacked or moved as a unit in this way.)
18
Free-floating stacked panels
To stack free-floating panels, drag a panel by its tab to the drop zone at the bottom of another panel.
To change the stacking order, drag a panel up or down by its tab.
Note: Be sure to release the tab over the narrow drop zone between panels, rather than the broad drop zone in a title bar.
To remove a panel or panel group from the stack, so that it floats by itself, drag it out by its tab or title bar.
Resize or minimize panels
To resize a panel, drag any side of the panel or drag the size box at its lower-right corner. Some panels, such as the
Color panel in Photoshop, cannot be resized by dragging.
To change the width of all the panels in a dock, drag the gripper at the top left of the dock.
To minimize a panel, panel group, or stack of panels, click the Minimize button in its title bar.
You can open a panel menu even when the panel is minimized.

To expand a single panel icon, click it.
To collapse an expanded panel back to its icon, click its tab, its icon, or the double arrow in the panel’s title bar.
If you select Auto-Collapse Icon Panels from the Interface or User Interface Options preferences, an expanded panel icon will collapse automatically when you click away from it.
To add a panel or panel group to an icon dock, drag it in by its tab or title bar. (Panels are automatically collapsed
to icons when added to an icon dock.)
To move a panel icon (or panel icon group), drag the bar that appears above the icon. You can drag panel icons up
and down in the dock, into other docks (where they appear in the panel style of that dock), or outside the dock (where they appear as free-floating, expanded panels).

Work with the Preset Manager

About the Preset Manager

The Preset Manager lets you manage the libraries of preset brushes, swatches, gradients, styles, patterns, contours, custom shapes, and preset tools that come with Photoshop. For example, you can use the Preset Manager to change the current set of preset items or create new libraries. After you load a library in the Preset Manager, you can access the library’s items in locations such as the options bar, palettes, dialog boxes, and so on.
46
In general, when you change a preset, Photoshop prompts you to save the changes as a new preset so that both the original and changed preset remain available.
Each type of library has its own file extension and default folder. Preset files are installed on your computer inside the Presets folder in the Adobe Photoshop CS3 application folder.

Plug-ins

About plug-in modules

Plug-in modules are software programs developed by Adobe Systems and by other software developers in conjunction with Adobe Systems to add features to Photoshop. A number of importing, exporting, and special­effects plug-ins come with your program. They are automatically installed in folders inside the Photoshop Plug-ins folder.
You can select an additional Plug-ins folder for compatible plug-ins stored with another application. You can also create a shortcut (Windows) or an alias (Mac OS) for a plug-instored in another folder on your system. You can then add the shortcut or alias to the plug-ins folder and use that plug-in with Photoshop.
Once installed, plug-in modules appear as options in the Import or Export menu; as file formats in the Open, and Save As dialog boxes; or as filters in the Filter submenus. Photoshop can accommodate a large number of plug-ins. However, if the list of installed plug-in modules becomes too long, Photoshop may not be able to display all the plug-ins in their appropriate menus. If so, newly installed plug-ins appear in the Filter > Other submenu.

Install a plug-in module

In Mac OS, you cannot run Photoshop in the Classic environment. Plug-ins originally intended to work on Mac OS 9 won’t appear.

Work with the History palette

You can use the History palette to jump to any recent state of the image created during the current working session. Each time you apply a change to an image, the new state of that image is added to the palette.
For example, if you select, paint, and rotate part of an image, each of those states is listed separately in the palette. When you select one of the states, the image reverts to how it looked when that change was first applied. You can then work from that state.
You can also use the History palette to delete image states and, in Photoshop, to create a document from a state or snapshot.
To display the History palette, choose Window > History, or click the History palette tab.

Make a snapshot of an image

TheSnapshotcommandletsyoumakeatemporarycopy(orsnapshot)ofanystateoftheimage.Thenewsnapshot is added to the list of snapshots at the top of the History palette. Selecting a snapshot lets you work from that version of the image.
Snapshots are similar to the states listed in the History palette, but they offer additional advantages:
You can name a snapshot to make it easy to identify.
Snapshots can be stored for an entire work session.
You can compare effects easily. For example, you can take a snapshot before and after applying a filter. Then select
the first snapshot, and try the same filter with different settings. Switch between the snapshots to find the settings you like best.
With snapshots, you can recover your work easily. When you experiment with a complex technique or apply an
action, take a snapshot first. If you’re not satisfiedwith the results, you can select the snapshot to undo all the steps.
Note: Snapshots are not saved with the image—closing an image deletes its snapshots. Also, unless you select the Allow Non-Linear History option, selecting a snapshot and changing the image deletes all of the states currently listed in the History palette.

Memory and performance

Allocate RAM to Photoshop

Photoshop displays the RAM available to Photoshop and the ideal range of RAM for Photoshop (a percentage of the total available RAM) in Performance preferences.
In Performance preferences, enter the amount of RAM you want to allocate to Photoshop in the Let Photoshop
Use text box. Alternatively, drag the slider.

Assigning scratch disks

When your system does not have enough RAM to perform an operation, Photoshop uses a proprietary virtual memory technology, also called scratch disks. A scratch disk is any drive or drive partition with free memory. By default, Photoshop uses the hard drive on which the operating system is installed as the primary scratch disk.
Photoshop detects and displays all available internal disks in the Preferences panel. Using the Preferences panel, you can enable other scratch disks to be used when the primary disk is full. Your primary scratch disk should be your fastest hard disk; make sure it has plenty of defragmented space available.
The following guidelines can help you assign scratch disks:
For best performance, scratch disks should be on a different drive than any large files you are editing.
Scratch disks should be on a different drive than the one used for virtual memory.
RAID disks/disk arrays are good choices for dedicated scratch disk volumes.
Drives with scratch disks should be defragmented regularly.

About bitmap images

Bitmap images—technically called raster images—use a rectangular grid of picture elements (pixels) to represent images. Each pixel is assigned a specific location and color value. When working with bitmap images, you edit pixels rather than objects or shapes. Bitmap images are the most common electronic medium for continuous-tone images, such as photographs or digital paintings, because they can more efficiently represent subtle gradations of shades and color.
58
Bitmap images are resolution-dependent—that is, they contain a fixed number of pixels. As a result, they can lose detail andappear jagged if they are scaled to high magnifications on-screen or ifthey are printed at alower resolution than they were created for.
3:1
24:1
Example of a bitmap image at different levels of magnification
Bitmap images sometimes require large amounts of storage space, and often need to be compressed to keep file sizes down when used in certain Creative Suite components. For instance, you compress an image file in its original appli­cation before you import it into a layout.
Note: In Adobe Illustrator, you can create bitmap effects in your artwork using filters, effects, and graphic styles.

About vector graphics

Vector graphics (sometimes called vector shapes or vector objects) are made up of lines and curves defined by mathe­matical objects called vectors, which describe an image according to its geometric characteristics.
PHOTOSHOP CS3
User Guide
3:1
24:1
Example of a vector image at different levels of magnification
You can freely move or modify vector graphics without losing detail or clarity, because they are resolution­independent—they maintain crisp edges when resized, printed to a PostScript printer, saved in a PDF file, or imported into a vector-based graphics application. As a result, vector graphics are the best choice for artwork, such as logos, that will be used at various sizes and in various output media.
The vector objects you create using the drawing and shape tools in Adobe Creative Suite are examples of vector graphics. You can use the Copy and Paste commands to duplicate vector graphics between Creative Suite compo­nents.

Combining vector graphics and bitmap images

When combining vector graphics and bitmap images in a document, it’s important to remember that how your artwork looks on-screen isn’t always how it will look in its final medium (whether commercially printed, printed on a desktop printer, or viewed on the web). The following factors influence the quality of your final artwork:
Transparency Many effects add partially transparent pixels to your artwork. When your artwork contains trans-
parency, Photoshop performs a process called flattening before printing or exporting. In most cases, the default flattening process produces excellent results. However, if your artwork contains complex, overlapping areas and you require high-resolution output, you will probably want to preview the effects of flattening.
Image Resolution The number of pixels per inch (ppi) in a bitmap image. Using too low a resolution for a printed
image results in pixelation—output with large, coarse-looking pixels. Using too high a resolution (pixels smallerthan what the output device can produce) increases the file size without increasing the quality of the printed output, and slows the printing of the artwork.
Printer resolution and screen frequency The number of ink dots produced per inch (dpi) and the number of lines
per inch (lpi) in a halftone screen. The relationship between image resolution, printer resolution, and screen frequency determines the quality of detail in the printed image.

Color channels

EveryPhotoshopimagehasoneormorechannels, each storing information about color elements in the image. The number of default color channels in an image depends on its color mode. By default, images in Bitmap, Grayscale, Duotone, and Indexed Color mode have onechannel; RGB and Lab images have three; and CMYK images have four. You can add channels to all image types except Bitmap mode images. For more information, see “Color modes” on page 110.
Channels in color images are actually grayscale images that represent each of the color components of an image. For example, an RGB image has separate channels for red, green, and blues color values.
PHOTOSHOP CS3
User Guide
In addition to color channels, alphachannels, can be added to an image for storing and editing selections as masks, andspotcolorchannelscanbeaddedtoaddspotcolorplatesforprinting.Formoreinformation,see“Channels”on page 264.

Bit depth

Bit depth specifies how much color information is available for each pixel in an image. The more bits of information per pixel, the more available colors and more accurate color representation. For example, an image with a bit depth
8
of 1 has pixels with two possible values: black and white. An image with a bit depth of 8 has 2 Grayscale mode images with a bit depth of 8 have 256 possible gray values.
RGB images are made ofthree color channels.An 8-bit per pixel RGB imagehas 256 possible values for each channel which means it has over 16 million possible color values. RGB images with 8-bits per channel (bpc) are sometimes called 24-bit images (8 bits x 3 channels = 24 bits of data for each pixel).
In addition to 8-bpc images, Photoshop can also work with images that contain 16-bpc or 32-bpc. Images with 32-bpc are also known as high dynamic range (HDR) images.

All tools in the toolbox, except the Art History Brush tool, can be used with 16-bpc images.
All color and tonal adjustment commands, except Variations, are available.
You can work with layers, including adjustment layers, in 16-bpc images.
Some filters, including Liquify, can be used with 16-bpc images.

Image size and resolution

About pixel dimensions and resolution

The pixel dimensions (image size or height and width) of a bitmap image is a measure of the number of pixels along an image’s width and height. Resolution is the fineness of detail in a bitmap image and is measured in pixels per inch (ppi). The more pixels per inch, the greater the resolution. Generally, an image with a higher resolution produces a better printed image quality.
61
Same image at 72-ppi and 300-ppi; inset zoom 200%
The combination of pixel dimension and resolution determine the amount of image data. Unless an image is resampled,theamountofimagedataremainsthesameasyouchangeeitherthepixeldimensionorresolution.Ifyou change the resolution of a file, its width and height change accordingly to maintain the same amount of image data. And, vice versa. For more information, see “Resampling” on page 64.
In Photoshop, you can see the relationship between image size and resolution in the Image Size dialog box (choose Image > Image Size). Deselect Resample Image, because you don’t want to change the amount of image data in your photo. Then change the width or the height or the resolution. As you change one value, the other two values change accordingly.

File size

The file size of an image is the digital size of the image file, measured in kilobytes (K), megabytes (MB), or gigabytes (GB). Filesize is proportional to the pixel dimensions ofthe image. Images with more pixelsmay produce more detail atagivenprintedsize,buttheyrequiremorediskspacetostoreandmaybeslowertoeditandprint.Imageresolution thus becomes a compromise between image quality (capturing all the data you need) and file size.
Another factor that affects file size is file format. Because of the varying compression methods used by GIF, JPEG, and PNG file formats, file sizes can vary considerably for the same pixel dimensions. Similarly, color bit-depth and the number of layers and channels in an image affect file size.
Photoshop supports a maximum pixel dimension of 300,000 by 300,000 pixels per image. This restriction places limits on the print size and resolution available to an image.

About monitor resolution

Your monitor’s resolution is described in pixel dimensions. For example, if your monitor resolution and your photo’s pixel dimensions are the same size, the photo will fill the screen when viewed at 100%. How large an image appears on-screen depends on a combination of factors—the pixel dimensions of the image, the monitor size, and the monitor resolution setting. In Photoshop,you can change the imagemagnification on-screen, so you can easily work with images of any pixel dimensions.

When preparing images for viewing on-screen, you should consider the lowest monitor resolution that your photo is likely to be viewed on.

About printer resolution

Printer resolution is measured in ink dots per inch, also known as dpi. Generally, the more dots per inch, the finer the printed output you’ll get. Most inkjet printers have a resolution of approximately 720 to 2880 dpi. (Technically, inkjet printers produce a microscopic spray of ink, not actual dots like imagesetters or laser printers.)
Printer resolution isdifferent from,but related to image resolution.Toprint a high quality photo on an inkjet printer, an image resolution of at least 220 ppi should provide good results.

Screen frequency and printer resolution
Screen frequency is the number of printer dots or halftone cells per inch used to print grayscale images or color separations. Also known as screen ruling or line screen, screen frequency is measured in lines per inch (lpi)—or lines of cellsper inch in a halftone screen.The higher theresolution ofthe output device, the finer (higher) ascreen ruling you can use.
The relationship between image resolution and screen frequency determines the quality of detail in the printed image. To produce a halftone image of the highest quality, you generally use an image resolution that is from 1.5 to at most 2 times the screen frequency. But with some images and output devices, alower resolution can producegood results. To determine your printer’s screen frequency, check your printer documentation or consult your service provider.
Note: Some imagesetters and 600-dpi laser printers use screening technologies other than halftoning. If you are printing an image on a nonhalftone printer, consult your service provider or your printer documentation for the recommended image resolutions.

Resampling

Resampling is changing the amount of image data as you change either the pixel dimensions or the resolution of an image. When you downsample (decrease the number of pixels), information is deleted from the image. When you resample up (increase the number of pixels, or upsample), new pixels are added. You specify an interpolation method to determine how pixels are added or deleted.

B
C
Resampling pixels A. Downsampled B. Original C. Resampled up (selected pixels displayed for each set of images)
Keep inmind that resampling can result in poorer image quality. For example, when you resample an imageto larger pixel dimensions, theimage loses somedetail and sharpness.Applying the Unsharp Mask filter to a resampled image can help refocus the image details.
PHOTOSHOP CS3
User Guide
You can avoid the need for resampling by scanning orcreating the image at a sufficiently high resolution. If you want to preview the effects of changing pixel dimensions on-screen or to print proofs at different resolutions, resample a duplicate of your file.
Photoshop resamples images using an interpolation method to assign color values to any new pixels based on the color values of existing pixels. You can choose which method to use in the Image Size dialog box.
Nearest Neighbor A fast but less precise method that replicates the pixels in an image. This method is for use with
illustrations containing edges that are not anti-aliased, to preserve hard edges and produce a smaller file. However, this method can produce jagged effects, which become apparent when you distort or scale an image or perform multiple manipulations on a selection.
Bilinear A method that adds pixels by averaging the color values of surrounding pixels. It produces medium-quality
results.
Bicubic A slowerbut more precise method based on anexamination of the values of surrounding pixels. Usingmore
complex calculations, Bicubic produces smoother tonal gradations than Nearest Neighbor or Bilinear.
Bicubic Smoother A good method for enlarging images based on Bicubic interpolation but designed to produce
smoother results.
Bicubic Sharper A good method for reducing the size of an image based on Bicubic interpolation with enhanced
sharpening. This method maintains the detail in a resampled image. If Bicubic Sharper oversharpens some areas of an image, try using Bicubic.
65
You can specify a default interpolation method to use whenever Photoshop resamples image data. Choose Edit >
Preferences > General (Windows) or Photoshop > Preferences > General (Mac OS), and then choose a method from the Image Interpolation Methods menu.

Change pixel dimensions of an image

Changing an image’s pixel dimensions affects not only its on-screen size but also its image quality and its printed characteristics—either its printed dimensions or its image resolution.
1 Choose Image > Image Size.
2 To maintain the current ratio of pixel width to pixel height, select Constrain Proportions. This option automati-
cally updates the width as you change the height, and vice versa.
3 Under Pixel Dimensions, enter values for Width and Height. To enter values as percentages of the current dimen-
sions, choose Percent as the unit of measurement. The new file size for the image appears at the top of the Image Size dialog box, with the old file size in parentheses.
4 Make sure that Resample Image is selected, and choose an interpolation method.
5 If your image haslayers with styles applied tothem, select Scale Styles to scale the effects inthe resized image. This
option is available only if you selected Constrain Proportions.

Change the print dimensions and resolution

When creating an image for print media, it’s useful to specify image size in terms of the printed dimensions and the image resolution. These two measurements, referred to as the document size, determine the total pixel count and therefore the file size of the image; document size also determines the base size at which an image is placed into another application. You can further manipulate the scale of the printed image using the Print command; however, changes you make using the Print command affect only the printed image, not the document size of the image file.
If you turn on resampling forthe image, you can change print dimensions and resolution independently (andchange the total number of pixels in the image). If you turn off resampling, you can change either the dimensions or the resolution—Photoshop adjusts the other value automatically to preserve the total pixel count. For the highest print quality, it’s generally best to change the dimensions and resolution first, without resampling. Then resample only as necessary.
1 Choose Image > Image Size.
2 Change the print dimensions, image resolution, or both:
To change only the print dimensions or only the resolution and adjust the total number of pixels in the image
proportionately, select Resample Image and then choose an interpolation method.
To change the print dimensions and resolution without changing the total number of pixels in the image, deselect
Resample Image.
3 To maintain the current ratio of image width to image height, select Constrain Proportions. This option automat-
ically changes the width as you change the height, and vice versa.
4 Under Document Size, enter new values for the height and width. If desired, choose a new unit of measurement.
NotethatforWidth,theColumnsoptionusesthewidthandguttersizesspecifiedintheUnits&Rulerspreferences.
5 For Resolution, enter a new value. If desired, choose a new unit of measurement.

Adobe Version Cue

Adobe® Version Cue® is a file-version manager included with Adobe Creative Suite 3 Design, Web, and Master Collection editions that consists of two pieces: the Version Cue Server and Version Cue connectivity. The Version Cue Server hosts Version Cue projects and PDF reviews, and can be installed locally or on a centralized computer. Version Cue connectivity enables you to connect to Version Cue Servers, and is included with all Version Cue-enabled components (Adobe Acrobat®, Adobe Flash®, Adobe Illustrator®, Adobe InDesign®, Adobe InCopy®, Adobe Photoshop®, and Adobe Bridge).
70
Use Version Cue to track changes to a file as you work on it, and to enable workgroup collaboration such as file sharing, version control, and online reviews. You can use Version Cue ina single Version Cue-enabledCreative Suite component, such as Photoshop, or across multiple components, such as Photoshop, Flash, and Illustrator.
You access Version Cue features by way of the Adobe dialog box or through Adobe Bridge, depending on whether you are using Version Cue-enabled software and whether or not you have installed a Creative Suite software set (for example, Adobe Creative Suite 3 Design Premium).
Version Cue handles the following tasks:
Creating versions of your files
Enabling workgroup collaboration (file sharing, version control, the ability to check files in and out)
Organizing files into private or shared projects
Providing thumbnails so you can browse and view files
Organizing data so you can view and search on file information, version comments, and file status
Creating and managing user access, projects, and PDF reviews by way of Version Cue Server Administration

Open files

You can open files using the Open command and Open Recent command. You can also open files into Photoshop from Adobe Bridge or Adobe® Photoshop® Lightroom™.
When opening certain files, such as camera raw and PDF, you specify settings and options in a dialog box before the files completely open in Photoshop.
In addition to still images, Photoshop® CS3 Extended users can open and edit video and image sequence files. For more information, see “Import video files and image sequences (Photoshop Extended)” on page 554.
Note: Photoshop uses plug-in modules to open andimport many file formats. If a file format does not appear in the Open dialog box or in the File > Import submenu, you may need to install the format’s plug-in module.
PHOTOSHOP CS3
User Guide
Sometimes Photoshop may not be able to determine the correct format for a file. This can happen, for example, because the file has been transferred between two operating systems. Sometimes a transfer between Mac OS and Windows can cause the file format to be mislabeled. In such cases, you must specify the correct format in which to open the file.
You can retain (where possible) layers, masks, transparency, compound shapes, slices, image maps, and editable type
when bringing your Illustrator art into Photoshop. In Illustrator, export the art in the Photoshop (PSD) file format. If your Illustrator art contains elements that Photoshop doesn’t support, the appearance of the artwork is preserved, but the layers are merged and the artwork is rasterized.

High dynamic range images

About high dynamic range images

Thedynamicrange(ratiobetweendarkandbrightregions)inthevisibleworldfarexceedstherangeofhumanvision and of images that are displayed on a monitor or printed. But whereas human eyes can adapt to very different brightness levels, most cameras and computer monitors can capture and reproduce only a fixed dynamic range. Photographers, motion picture artists, and others working with digital images must be selective about what’s important in a scene because they are working with a limited dynamic range.
High dynamic range (HDR) images open up a world of possibilities because they can represent the entire dynamic range of the visibleworld. Because all the luminancevalues in a real-world scene are represented proportionately and stored in an HDR image, adjusting the exposure of an HDR image islike adjusting theexposure when photographing a scene in the real world. This capability lets you create blurs and other real-world lighting effects that look realistic. Currently, HDR images are used mostly in motion pictures, special effects, 3D work, and some high-end photog­raphy.

In Photoshop, the luminance values of an HDRimage are stored using a floating-point numeric representation that’s 32 bitslong (32-bits-per-channel). Theluminance values in an HDR image are directly related to the amount of light in a scene. This is not so with (non-floating point) 16-bits-per-channel (bpc) and 8-bpc image files, which can store luminance values only from black to paper white; this represents an extremely small segment of the dynamic range in the real world.
Adobe Photoshop CS3 now offers layers support for 32-bpc images, as well as access to more tools, filters, and commands. 32 bit has been added as an option when creating new documents in Photoshop. For more information, see below.
Another added feature is painting on 32-bpc images. Enhancements have been made to the Adobe Color Picker so you can specify colors that have a brightness intensity that exceeds 1.0 (the equivalent ofthe 255 levelin an 8-bit RGB document). See also “About the HDR Color Picker (Photoshop Extended)” on page 83.
You can create an HDR image using multiple photographs, each captured at a different exposure. In Photoshop, the Merge To HDR command lets you create HDR images from multiple photographs. Because an HDR image contains brightness levels thatfar exceed the display capabilities of astandard 24-bitmonitor or therange of tones in aprinted image, Photoshop lets you adjust the preview of the HDR image so it can be viewed on a computer monitor. If you need to print the image or use Photoshop tools and filters that don’t work with HDR images, you can convert the HDR image to an 8- or 16-bpc image.
Photoshop support for 32-bpc images
Use the following tools, adjustments, and filters with 32-bpc HDR images:
Adjustments Levels, Cut Down Saturation, Hue/Saturation, Channel Mixer, Photo Filter, and Exposure.
Note: Although the Exposure command can be used with 8- and 16-bpc images, it is designed for making exposure adjustments to 32-bpc HDR images.

Be sure to choose 32 Bits/Channel if you want the merged image to store the entire dynamic range data of the HDR image. 8-bits and (non-floating point) 16-bpc images files cannot store the entire range of luminance values in an HDR image.
8 Move the slider below the histogram to preview the merged image.
Moving the slider adjusts the image preview only. All the HDR image data remains intact in the merged image file. If you’re saving the merged image as 32-bpc, the preview adjustment is stored in the HDR image file and applied whenever the file is opened in Photoshop. The preview adjustment is always accessible and adjustable by choosing View > 32-Bit Preview Options.
9 Click OK to create the merged image.
If you chose to save the merged image as an 8-bits or 16-bpc image, the HDR Conversion dialog box opens. Make the exposureand contrast corrections to produce an imagewith the dynamic range (tonal range) you want. For more information, see “Convert from 32 bits to 8 or 16 bpc” on page 81.
Take photos for merging to HDR
Keep the following tips in mind when you take photos to be combined with the Merge To HDR command:
Secure the camera to a tripod.
Take enough photos to cover the full dynamic range of the scene. You can try taking at least five to seven photos,
but you might need to take more exposures depending on the dynamicrange of the scene. The minimum number of photos should be three.
PHOTOSHOP CS3
User Guide
Vary the shutter speed to create different exposures. Changing the aperture changes the depth of field in each
exposure and can produce lower-quality results. Changing the ISO or aperture may also cause noise or vignetting in the image.
In general, don’t use your camera’s auto-bracket feature, because the exposure changes are usually too small.
The exposure differences between the photos should be one or two EV (exposure value) steps apart (equivalent to
about one or two f-stops apart).
Don’t vary the lighting; for instance, don’t use a flash in one exposure but not the next.
Make sure that nothingis moving in the scene. Exposure Merge works only with differentlyexposed images of the
identical scene.

Adjust dynamic range view for HDR images

The dynamic range of HDR images exceeds the display capabilities of standard computer monitors. When you open an HDR image in Photoshop, it can look very dark or washed out. Photoshop lets you adjust the preview so that the monitor displays an HDR image whose highlights and shadows aren’t washed out or too dark. The preview settings are stored in the HDR image file (PSD, PSB, and TIFF only) and are applied whenever the file is opened in Photoshop. Preview adjustments don’t edit the HDR image file, all the HDR image information remains intact. Use the Exposure adjustment (Image > Adjustments > Exposure) to make exposure edits to the 32-bpc HDR image.

Chapter 4: Camera Raw

AdobePhotoshopCameraRawsoftwareworkswithAdobePhotoshop,AdobeAfterEffects,andAdobeBridge.You can use Photoshop Camera Raw software to import and adjust camera raw, JPEG, and TIFF files.

Introduction to Camera Raw

About camera raw files

A camera raw file contains unprocessed, uncompressed grayscale picture data from a digital camera’s image sensor, along with information about how the image was captured (metadata). Photoshop Camera Raw software interprets the camera raw file, using information about the camera and the image’s metadata to construct and process a color image.
Think of a camera raw file as your photo negative. You can reprocess the file at any time, achieving the results that you want by making adjustments for white balance, tonal range, contrast, color saturation, and sharpening. When you adjust a camera raw image, the original camera raw data is preserved. Adjustments are stored as metadata in an accompanying sidecar file, in a database, or in the file itself (in the case of DNG format).
85
When you shoot JPEG files with your camera, the camera automatically processes the JPEG to enhance and compress the image. You generally have little control over how this processing occurs. Shooting camera raw images with your camera gives you greater control than shooting JPEG images, because camera raw does not lock you into processing done by your camera. You can still edit JPEG and TIFF images in Camera Raw, but you will be editing pixels that were already processed by the camera. Camera raw files always contain the original, unprocessed pixels from the camera.
To shoot camera raw images, you need to set your camera to save files in its own camera raw file format.
Note: The Photoshop Raw format (.raw) is a file format for transferring images between applications and computer platforms. Don’t confuse Photoshop raw with camera raw file formats.
Digital cameras capture and store camera rawdata with a linear tone response curve (gamma 1.0). Both film and the human eye have a nonlinear, logarithmic response to light (gamma greater than 2). An unprocessed camera raw image viewed as a grayscale image would seem very dark, because what appears twice as bright to the photosensor and computer seems less than twice as bright to the human eye.

About Camera Raw

Camera Raw software is included as a plug-in with Adobe After Effects and Adobe Photoshop, and also adds functionality to Adobe Bridge. Camera Raw gives each of these applications the ability to import and work with camera raw files. You can also use Camera Raw to work with JPEG and TIFF files.
You must have Photoshop or After Effects installed to open files in the Camera Raw dialog box from Bridge. However, if Photoshop or After Effects is not installed, you can still preview the images and see their metadata in Bridge. If another application is associated with the image file type, it’s possible to open the file in that application from Bridge.
PHOTOSHOP CS3
User Guide
Using Bridge, you can apply, copy, and clear image settings, and you can see previews and metadata for camera raw files without opening them in the Camera Raw dialog box. The preview in Bridge is a JPEG image generated using the current image settings; the preview is not the raw camera data itself, which would appear as a very dark grayscale image.
Note: A caution icon appears in the thumbnails and preview image in the Camera Raw dialog box while the preview is generated from the camera raw image.
You can modify the default settings that Camera Raw uses for a particular model of camera. For each camera model, you can also modify the defaults for a particular ISO setting or a particular camera (by serial number). You can modify and save image settings as presets for use with other images.
When you use Camera Raw to make adjustments (includingstraightening and cropping) to a camera raw image, the image’s original camera raw data is preserved. The adjustments are stored for each image in either the Camera Raw database, as metadata embedded inthe imagefile, or in a sidecar XMP file (ametadata file that accompaniesa camera raw file). For more information, see “Specify where Camera Raw settings are stored” on page 104.
After you process and edit a camera raw file using the Camera Raw plug-in, an icon appears in the image thumbnail in Bridge.
If you open a camera raw file in Photoshop,you can save the imagein other image formats, such as PSD, JPEG, Large Document Format (PSB), TIFF, Cineon, Photoshop Raw, PNG, or PBM. From the Camera Raw dialog box in Photoshop, you can save the processed files in Digital Negative (DNG), JPEG, TIFF, or Photoshop (PSD) formats. Although Photoshop Camera Raw software can open and edit a camera raw image file, it cannot save an image in a camera raw format.
86
Note: In Photoshop, the Camera Raw dialog box is automatically suppressed when youuse a batch offiles for a webphoto gallery, picture package, or contact sheet.
As new versions of Camera Raw become available, you can update this software by installing a new version of the plug-in. You can check for updates to Adobe software by choosing Help > Updates.
For up-to-date documentation for Camera Raw, go to the Adobe website at
www.adobe.com/go/learn_ps_camerarawhelp.
Different camera models save camera raw images in many different formats, and the data must be interpreted differ­ently for these formats. Camera Raw includes profiles for many camera models, and it can interpret many camera raw formats.
Note: For a list of supported cameras and for more information about Camera Raw, see
www.adobe.com/go/learn_ps_cameraraw.

About the Digital Negative (DNG) format

The Digital Negative (DNG) format is a non-proprietary, publicly documented, and widely supported format for storing raw camera data. Hardware and software developers use DNG because it results in a flexible workflow for processing and archiving camera raw data. You may also use DNG as an intermediate format for storing images that were originally captured using a proprietary camera raw format.
Because DNG metadata is publicly documented, software readers such as Camera Raw do not need camera-specific knowledge to decode and process files created by a camera that supports DNG. If support for a proprietary format is discontinued, users may not be able to access images stored in that format, and the images may be lost forever. Because DNG is publicly documented, it is far more likely that raw images stored as DNG files will be readable by software in the distant future, making DNG a safer choice for archival storage.
PHOTOSHOP CS3
User Guide
DNG is an extension of the TIFF 6.0 format and is compatible with the TIFF-EP standard. It is possible (but not required) for a DNG file to simultaneously comply with both the Digital Negative specification and the TIFF-EP standard.
Metadata for adjustments made to images stored as DNG files can be embedded in the DNG file itself instead of in a sidecar XMP file or in the Camera Raw database.
YoucanconvertcamerarawfilestotheDNGformatbyusingtheAdobeDNGConverterortheCameraRawdialog box. For more information on the DNG format and DNG Converter, see www.adobe.com/go/learn_ps_dng.

Processing images with Camera Raw

1. Copy camera raw files to your hard disk, organize them, and (optionally) convert them to DNG.
Before you do any work on the images that your camera raw files represent, transfer them from the camera’s memory card, organize them,give them useful names, and otherwise prepare them for use. Use the Get Photos From Camera command in Bridge to accomplish these tasks automatically.
2. Open the image files in Camera Raw.
You can open camera raw files in Camera Raw from Bridge, After Effects, or Photoshop. You can also open JPEG and TIFF files in Camera Raw from Bridge. (See “Open images in Camera Raw” on page 92.)

Work with the Camera Raw cache in Bridge

When you view camera raw files inAdobe Bridge, the thumbnails and previews use eitherthe default settings or your adjusted settings. The cache in Bridge and the Camera Raw cache store data for the file thumbnails, metadata, and file information. Caching this data shortens the loading time when you return to a previously viewed folder.
Because caches can become very large, you may want to purge the cache or limit its size. You can also purge and regenerate the cache if you suspect that it is corrupted or old. Purging the cache deletes thumbnail information and metadata added since the camera raw file was opened in Bridge.
Note: The Camera Raw cache holds data for about 200 images for each gigabyte of disk storage allocatedto it. By default, the Camera Raw cache is set to a maximum size of 1 GB. You can increase its limit in the Camera Raw preferences.
1 In Bridge, choose Edit > Camera Raw Preferences (Windows) or Bridge > Camera Raw Preferences (Mac OS), or,
with the Camera Raw dialog box open, click the Open Preferences Dialog button .
2 Do any of the following:
To change the cache size, enter a Maximum Size value.
To purge the camera raw cache, click the Purge Cache button.
To change the location of the camera raw cache, click Select Location.

Navigating, opening, and saving images

Process, compare, and rate multiple images in Camera Raw

The most convenient way to work with multiple camera raw images is to use the Filmstrip view in Camera Raw, which opens by default when you open multiple images in Camera Raw from Bridge.
Images can have three states in Filmstrip view: deselected, selected (but not active), and active (also selected). In general, adjustments are applied to all selected images.
PHOTOSHOP CS3
User Guide
You can also synchronize settings toapply settingsfrom the active image to all selected images.You can quickly apply a set of adjustments to an entire set of images—such as all shots taken under the same conditions—and then do fine­tuning on the individual shots later, after you’ve determined which you’ll use for your final output.
To select an image, click its thumbnail. To select a range of images, Shift-click two thumbnails. To add an image
to a selection, Ctrl-click (Windows) or Command-click (Mac OS) its thumbnail.
To change which image is active without changing which images are selected, click a navigation arrow at
the bottom of the preview pane.
To apply settings from the active image to all selected images, click the Synchronize button at the top of the
Filmstrip pane and choose which settings to synchronize.
To apply a star rating, click a rating under the image thumbnail.
To mark selected images for deletion, click Mark For Deletion .
A red cross appears in the thumbnail of an image marked for deletion. The file is sent to the Recycle Bin (Windows) or Trash (Mac OS) when youclose the Camera Rawdialog box. (If you decide to keepan imagethat you marked for deletion, select it in the Thumbnail pane and click Mark For Deletion again, before you close the Camera Raw dialog box.)

Automating image processing with Camera Raw

You can create an action to automate the processing of image files with Camera Raw. You can automate the editing process, and the process of saving the files in formats such as PSD, DNG, JPEG, Large Document Format (PSB), TIFF, and PDF. In Photoshop, you can also use the Batch command, the Image Processor, or the Create Droplet command to process one or more image files. The Image Processor is especially useful for saving image files in different file formats during the same processing session.
91
Here are some tips for automating the processing of camera raw image files:
When you record an action, first select Image Settings from the Camera Raw Settings menu in the Camera Raw
dialog box. In this way, thesettings particular to each image (from the Camera Raw database or sidecar XMPfiles) are used to play back the action.
IfyouplantousetheactionwiththeBatchcommand,youmaywanttousetheSaveAscommandandchoosethe
file format when saving the camera raw image.
When you use an action to open a camera raw file, the Camera Raw dialog box reflects the settings that were in
effect when the action was recorded. You may want to create different actions for opening camera raw image files with different settings.
WhenusingtheBatchcommand,selectOverrideAction“Open”Commands.AnyOpencommandsintheaction
will then operate on the batched files rather than the files specified by name in the action. Deselect Override Action “Open” Commands only if you want the action to operate on open files or if the action uses the Open command to retrieve needed information.
WhenusingtheBatchcommand,selectSuppressFileOpenOptionsDialogstopreventthedisplayoftheCamera
Raw dialog box as each camera raw image is processed.
When using the Batch command, select Override Action “Save As” Commands if you want to use the Save As
instructions from the Batch command instead of the Save As instructions in the action. If you select this option, theactionmustcontainaSaveAscommand,becausetheBatchcommanddoesnotautomaticallysavethesource files. Deselect Override Action “Save As” Commands to save the files processed by the Batch command in the location specified in the Batch dialog box.
When creating a droplet, select Suppress File Open Options Dialogs in the Play area of the Create Droplet dialog
box. This prevents the display of the Camera Raw dialog box as each camera raw image is processed.

Placing or dragging image stacks from Bridge into After Effects imports them as an image sequence. Add an extra
bullet specific to importing camera raw files as a sequence into After Effects. Camera Raw settings applied to the first camera raw file upon import are applied to the remaining files in the sequence unless an XMP sidecar file is present for any subsequent file in the sequence. In that case, the settings in the XMP file or in the DNG file are applied to that specific frame in the sequence, all other frames use the settings that the first file in the sequence specifies.

Save a camera raw image in another format

You can save camera raw files from the Camera Raw dialog box in PSD, TIFF, JPEG, or DNG formats.
When you use the Save command in the Camera Raw dialog box, files are placed in a queue to be processed and saved. This is useful if you are processing several files in the Camera Raw dialog box and saving them in the same format.
1 In the Camera Raw dialog box, click the Save button in the lower-left corner of the dialog box.
PHOTOSHOP CS3

Destination Specifies where to save the file. If necessary, click the Select Folder button and navigate to the location.
File Naming Specifies the file nameusing a naming conventionthat includes elements such asdate and camera serial
number. Using informative file names based on a naming convention helps you keep image files organized.
3 Choose a file format from the Format menu.
4 Click Save.
Format options
Digital Negative Saves a copy of the camera raw file in the DNG file format.
Compressed (lossless) Uses lossless compression, meaning that no information is lost while reducing the file size.
Convert To Linear Image Stores theimage datain aninterpolated (demosaiced)format. The resulting interpolated
image can be interpreted by other software even if that software does not have a profile for the digital camera that captured the image.
Embed Original Raw File Stores all of the original camera raw image data in the DNG file.
93
JPEG Preview Embeds a JPEG preview in the DNG file. If you decide to embed a JPEG preview, you can choose
the preview size. If you embed JPEG previews, other applications can view the contents of the DNG file without parsing the camera raw data.
JPEG Saves copies of the camera raw files in JPEG (Joint Photographic Experts Group) format. To specify the
amount of compression, enter a value from 0 to 12 or choose from the menu. Entering a higher value, or choosing High or Maximum, applies less compression and increases file size and image quality. JPEG format is commonly used todisplay photographsand othercontinuous-toneimages in web photogalleries, slideshows, presentations, and other online services.
TIFF Saves copies of the camera raw files as TIFF (Tagged-Image File Format) files. Specify whether to apply no
compression, or LZW or ZIP file compression. TIFF is a flexible bitmap image format supported by virtually all paint, image-editing, and page-layout applications. TIFF provides greater compression and compatibility with other applications than does PSD format.
Photoshop Saves copies of the camera raw files in the PSD file format. You can specify whether to preserve cropped
pixel data in the PSD file.

Making color and tonal adjustments in Camera Raw

Using histogram and RGB levels in Camera Raw

A histogram is a representation of the number of pixels at each luminance value in an image. A histogram that has nonzero values for each luminance value indicates an image that takes advantage of the full tonal scale. A histogram that doesn’t use the full tonal range corresponds to a dull image that lacks contrast. A histogram with a spike at the left side indicates shadow clipping; a histogram with a spike on the right side indicates highlight clipping.
Select Shadows or Highlights to see, in the preview image, which pixels are being clipped. For more information, see
“Preview highlight and shadow clipping in Camera Raw” on page 94.
