Pros:  Well-designed new interface; selective editing in Camera Raw; Collections in Bridge; improved dodge, burn and saturation tools; amazing content-aware scaling; interactive brush resizing. 

Cons: Bridge still not well-suited for refined comparisons of images; no histogram display in Bridge; Loupe in Bridge still has technical problems; no dedicated straightening tool in Photoshop; Camera Raw selective editing doesn t let you selectively apply white balance. 

Score: 95 

This is what a must-have upgrade looks like: 

* New features you'll use regularly 
* Fixes to old features 
* Performance and stability enhancements 
* Interface improvements (that don t interfere with the stuff you already like) 

Tick off every one of those points and you get Photoshop CS4. 

Whether you re a photographer, designer, special effects wizard, or any other kind of Photoshopaholic, this upgrade could have a bigger impact on your work life than a major upgrade to your computer s operating system. 

There are lots of things to explore in the standard edition of Photoshop CS4. I'll introduce you to the changes as you might encounter them in a typical photography workflow.
