Adobe® Photoshop® CS4 and Photoshop CS4 Extended
An in-depth look at key new features and enhancements

This article does not cover all of the new or enhanced features in Photoshop CS4 and Photoshop CS4 Extended. Instead, it details some of the more technical additions, such as workflow optimization, printing and color management and Camera Raw.

Workflow optimization

Designed to streamline workflows for everyone who uses Photoshop, these features shorten time by either providing superior results with less adjustment, decreasing mouse movements, or enabling alternate methods to accomplish a given workflow.

Adjustment layers

The new Adjustments panel makes accessing, creating, and reediting Adjustment layers faster and easier by orders of magnitude, eliminating from the workflow the need to navigate multiple dialog boxes. As it is a nonmodal panel, you no longer need to stop using Photoshop tools and menus while you interact with the adjustment layers—all tools, menus, and controls can be used in conjunction with those that create and edit adjustment layers in the Adjustments panel. The panel includes 22 new presets and lets you create your own. Also available is the new Vibrance adjustment, on-image controls for the Hue/Saturation and Curves adjustments, and many enhancements to existing adjustments.

Masks

The new Masks panel enables faster, more intuitive creation and editing of masks, in much the same way that the Adjustments panel improves adjustment layer use. In addition, a new ability has been added to adjust the density (opacity) of a layer mask, as well as nondestructive feathering. The density control affects only the mask itself, whether pixel or vector. Opacity affects the complete layer contents, including layer effects. Fill affects only the layer contents themselves. The Mask Edge command in the Masks panel also allows nondestructive mask refinement, as opposed to the destructive method when using the Select > Refine Edge command.

Improved Color Range

These selection tools have been greatly enhanced and made more accessible, including the ability to select multiple color ranges, to adjust the tolerance of the selected color range (“fuzziness”), and to adjust the range of the selection, where the range is the radial distance from the center of the sampled area. Color Range now automatically generates a mask as it’s used, and all refinements are made nondestructively.

Printing and color management
Images are created in Adobe Photoshop CS4 for output to devices ranging from desktop printers to offset presses, as well as the web, film and television, and more. Photoshop CS4 includes a number of enhancements to both the printing interface and print options for color management, including:

• 16-bit printing— Full, 16-bit data can now be sent to compatible printers when Photoshop is running on Mac OS X systems (version 10.5 and later).
• Large-document printing— Documents larger than 30,000 pixels in size can now be printed.
• Increased scripting support— This enhancement enables more automated print output.
• Support for device link color profiles— These profiles transform images from one device color space to another, without using an intermediate color space.
• Support for abstract color profiles— These profiles are used for custom image effects, allowing the generation of custom lookup tables.
• Support for N-color/multichannel imaging— These profiles support more than four color channels for specialized printing.
• Support for scene-referred color profiles— These profiles are used to carry the brightness differences captured by the camera through to output, even when the brightness levels cannot
  be accurately displayed on a computer monitor.

Camera Raw
Accessible from the Adobe Bridge main display or carousel view (by pressing the R key), and directly within Photoshop, Camera Raw enables you to control the processing of raw data from capable digital cameras and to perform nondestructive editing on the data, which is stored as instructions in metadata. As well as now supporting over 200 proprietary raw formats plus all TIFF and JPEG files, Camera Raw in Photoshop CS4 adds new capabilities, enhances existing features, and is harmonized with the Develop module in Photoshop Lightroom 2, so that changes made in one application can be recognized and displayed in the other.

Localized correction
No longer restricted to global adjustments, the Adjustment Brush allows you to precisely control the region of an image affected by the adjustment. Multiple areas can be designated in the same image, with specific individual adjustments for each area. Using the Auto Mask option enables edge detection so that it becomes easier to target specific parts of an image to be affected.

Graduated Filter
The Graduated Filter provides a different type of localized correction, allowing you to specify one or more gradient paths in the image, and then to apply multiple graduated effects along their lengths.

Post-Crop Vignetting
Once you set a crop in an image, you lose the vignetting along the sides of the image that are cropped away. With fine controls for feathering and roundness, Post-Crop Vignetting allows you to re-create preexisting vignetting, or create and adjust new vignetting, to achieve the desired effect in the final image.
