"Photoshop CS2 will be the tenth upgrade of Photoshop that I have purchased over the past ten or so years. Earlier releases were uniformly greeted with great enthusiasm (in Photoshop 3.0 - Adobe gave us Layers; in Photoshop 4.0 - they gave us Adjustment Layers; and in Photoshop 5.0 - they provided Color Management). But recent releases have often be meet by a significant amount of scorn and complaints about the lack of really interesting new features; a quick scan of various digital photography websites, Blogs and forums reveals a modest stream of complaints about the limited new features in the latest release of Photoshop. Well, I’d like to make the argument that Photoshop CS2 is overwhelmingly worth the upgrade price, and introduce you to a few of the features that I think make my photographic life easier." As time goes on, I find the new features in Photoshop less and less important to me. I think I'll be staying on Photoshop CS 1 and PS Elements 3 for now. But you should read up on and see if any of the new features are of interest to you (I do have to admit, Merge to HDR sounds interesting).
