I just picked up Adobe Photoshop CS4 today! I love it. I have a lot of learning to do (since I had CS2). There are a lot of AwEsOmE new features. The B&W editor is really cool. For some reason, my previous version never had the RAW editor. Now I do and I love it.
The only problem is that I had dozens of actions in CS2 and I need to figure out how to convert them or just creat new ones. I am sure my worflow will be different for a while until I get used to this new program.
Anyway, I just wanted to share that!
