Adobe has announced Creative Suite 4 on September 23!
New features in Photoshop CS4 of interest to photographers include:
Completely revamped interface
The Photoshop interface has had a major overhaul this time. Palettes has been replaced by tabs and panels, which you can group as you like. The GUI is accelerated by modern GPUs in a number of ways, and non-destructive adjustments now has its own panel. Flash-based panels are possible, among the included examples are the Kuler application for color harmonies. Image zooms at odd intervals, such as 66,6% and 33,3% are now sharper and less ‘pixelized’.
Content Aware Scaling
You can now scale an image, and intelligent code will ‘invent’ new data for enlargement or remove data intelligently for reductions, without altering important elements of your photo.
Camera RAW 5.0
Camera RAW 5.0 has many improvements. Of most importance are the new and improved color profiles for all cameras. It is now possible to choose color profiles that closely match that of your camera vendors, such as Canons ‘picture styles’. Adobes own color profiles has been updated to give more accurate and pleasing color. Local corrections are now possible via brushes or gradient masks, and most of the image editing options of Lightroom has now made its way into ACR.
Non destructive masking
PSCS4 has a new Mask panel for non-destructive masking. You can control feathering and density, and use the Refine Edge technology of CS3, all non-destructively.
Improved stitching and blending
Photomerge has been further developed, and now also feature lens distortion correction. A new feature is focus blending for extended depth of field from several source images.
On the Windows platform, you can take advantage of the larger RAM address space in 64bit.
Bridge is now faster and more useful than ever. Task-based workspaces increases efficiency, and new web galleries and PDF contact sheets are welcome additions. Auto-stacking analyzes and sorts your images in sequences for HDR or panoramas.
