Photoshop CS6 Beta: Welcome to the Dark Side
The most obvious change to Adobe Photoshop CS6 is its darkened interface. If you work in Lightroom, then you are already familiar with a dark gray workspace. If not, this Lynda.com video by Deke McClelland is a good introduction.
Why did Adobe decide to do an about-face? A gray backdrop allows you to focus on the image rather than be distracted what's going on around it. Think of it as a mat in a framed picture. The mat isolates the image in the frame, thereby drawing attention to the image itself.
Another reason is that gray is a neutral color. This means that the colors you see in an image are not affected by any other colors around it. While a neutral-colored interface by no means guarantees color fidelity — you'll still need to color calibrate your monitor to achieve consistent on-screen color — it does give you a better platform on which to base color decisions.
However, if the gray backdrop isn't to your liking or if you want to customize your workspace, there are several ways in which you can adjust it. In this video clip, Deke McClelland shows you how.
