There are a lot of differences between 7 and CS and many of those were specifically made with photographers in mind. Off the top of my head: - 16-bit editing beyond basic stuff (this is the big one in my opinion - I can edit front to back in 16-bit/channel mode even using most of the filters) - History Log (can't believe how no one talks about this - the ability to create a log file that shows all your edits; never forget how you did that cool thing again) - Shadow/Highlights adjustment (very cool) - Match Color adjustment - Photo Filters - Lens Blur Filter - Color Replacement tool - Photomerge - Filter Gallery - File Browser is improved with better features, integration and is now just slow instead of unbearably slow. :) - Live Histogram - Text on a Path - Layer comps - User definable hotkeys Plus I don't remember if they had this in PS 7, but I don't remember it. It's a convenience thing. I think they call them scrubbers or pushers (scrubbers sounds right). You go to a numeric field (like opacity, flow or whatever). You place your cursor over the word for that field and you should see the cursor change to a finger with arrows going left and right. If you hold down your left mouse button and move back and forth, the numbers in the field changes with it. I love that. :) There's lots more, that just what I can think of. -=>Donald
