The 3D features in Photoshop CS3 were an impressive first step, but even at the time there were questions about some shortcomings such as its inability to create its own 3D shapes. Photoshop CS4 Extended has proven itself to be the next step in the evolution of Photoshop as a 3D-ready application:
Working with 3D objects in Photoshop CS4 has been improved—for example, you can now edit artwork on the fly. Click the image for a larger view.
Probably the one question to be raised about all these 3D features is whether or not they are being used much in the field. I attended a color-correction session recently and it was asked if anyone was using the new features in the Extended version of Photoshop (CS3 Extended and/or CS4 Extended). No one could really think of any that were must-have tools, though to be fair this was a group of color-correction students and most of their daily work involved a specific set of tools. But I think Adobe sometimes has to grapple with the riddle of whether or not to add tools to Photoshop when it could be said they are simply stuffing the application in order to meet the expectation of an upgrade every 18 months. The 3D tools in Photoshop CS4 Extended are impressive but their usefulness ultimately depends on their being used.
When I write reviews on Adobe applications, there always seems to be a point where all I can do is lump the smaller improvements in one section—there’s too many to write about! Here are some of the more impressive improvements that you may or may not have heard about:

One more feature I didn’t write about: you can combine images with multiple focal points into one image with sharp depth of field throughout the image.
I have a love-hate relationship with Adobe Bridge. I was a big fan of Bridge’s precursor, the File Browser in Photoshop 7. I was glad to see it evolve into a full application with the launch of CS, but sluggish performance and a failure to find its niche made it the black sheep of the Adobe Creative Suite family (along with Version Cue). I used Bridge when it first came out but quit because it just didn’t perform well and the RSS-based Bridge Home was removed. Now Bridge is up to version 4 and it has some new features:
There’s several more features in Bridge CS4, but I think the one thing everyone wants is “faster performance.” Yes, Bridge CS4 is touted as having “faster performance” and I do think it’s improved over Bridge CS3 to the point where it’s actually quite usable. But if your computer is old and tired then don’t expect Bridge CS4 to be blazing fast. Again, I use a MacBook Pro with 3GB RAM and I sometimes have trouble getting Bridge up and running at top speed. Going into directories with a bunch of images can bring things to a standstill for several seconds. However, back when Bridge first came out I made it my file browser, residing on a second monitor all to itself. I eventually had to turn it off due to poor performance, but Bridge CS4 is good enough that I plan to reinstate it as my file browser of choice.
Photoshop CS4 and Photoshop CS4 Extended are both interesting upgrades. They are not for everyone—several changes in long-standing keyboard shortcuts have annoyed longtime users, including me—but there are some amazing new features and technologies at work. Some new features fall flat for me, while others amaze me. Likewise, Bridge CS4 is an improvement over Bridge CS3 but it’s not perfect by quite a bit. Ultimately I would recommend any Photoshop user to look at the CS4 upgrade long and hard before purchasing—it’s a great upgrade for some and dubious for others. If you are a Creative Suite user and want to upgrade to CS4, I wouldn’t let any shortcomings in Photoshop CS4 keep you from upgrading and enjoying the other great features in the rest of the applications.

[...] My recent review of Photoshop CS4 Extended dinged the Adjustments and Masks panels, which I thought were not much more than repackaged features that Photoshop already had. I wasn’t sure the change was necessary for Photoshop’s advanced user base. In contrast, Photoshop Elements sports a new tool that leverages pre-existing tools but has a much stronger rationale. The Smart Brush, which is basically a combination of the Quick Selection tool and adjustment layers, simplifies the selection and adjustment process for beginner and intermediate users. The Smart Brush is a helpful combination of selection and adjustment technology. Click the image for a larger view. [...]
[...] Some of the CS4 applications I’ve reviewed have been somewhat disappointing (Photoshop) while others have turned out to be radical upgrades with varying degrees of success (Dreamweaver, Flash). InDesign CS4 is, in my opinion, one of the best upgrades in CS4 suite: none of its new features really miss the mark, and most of them are quite useful (and a few are excellent advances in InDesign’s evolution). In my daily work I use InDesign CS4 more than probably any other Adobe application, and it has been a treat to use. [...]
