What is the difference between Adobe Photoshop 7 and Adobe Photoshop CS?

CS has more features, like better RAW support and the way filters are displayed, the colour replacement tool, etc.

Though it'd probably be better if you compared Photoshop CS and CS2.

I suggest searching the forum and/or trying those versions out to find out the differences.

I'm pretty sure it's a hefty difference because the update price for Adobe CS program was almost as much as buying a new CS program itself. Though CS and CS2 there really isint much of a difference and the update price was very cheap.

You have to search articles and other things about it. I'm sure you will many inquieries on the topic.
