Adobe Photoshop, or simply Photoshop, is a graphics editing program developed and published by Adobe Systems.
It is the current and primary market leader for commercial bitmap and image manipulation, and is the flagship product of Adobe Systems. It has been described as “an industry standard for graphics professionals” and was one of the early “killer applications” on Macintosh.
Some of the new features include:
Enhanced masking feature
Layer Mask Density option allows you to fade away the effect of a layer mask gradually revealing the parts that are hidden.
Real-time filters with no color depth restrictions
New Adobe technology called Hydra allows filters to use graphics card power in image processing instead of the CPU. That means all operations will be much faster. Hydra filters support all color depths as well.
Enhanced 3D features
New and better 3D features are available including painting diffuse maps, bump and glossiness maps among others directly on 3d models.
Enhanced Quick Selection tool
The Refine Edge dialog now has a new feature to deals much better with complex surfaces such as fur ensuring a more defined line between subject and background.
Improved Dodge and Burn tools
Improved algorithm in these tools lets results look less destructive and more natural.
Polished interface
Photoshop interface brightness will be adjustable like in Adobe Bridge with buttons and dialog boxes look will be improved.
Extended and enhanced color profile management.
Multichannel, Device-Link and Abstract color profiles to be added.
