I stopped upgrading Photoshop once I reached version 7. The simple reason is that v7 has handled all my needs just fine. I use it almost every day for a variety of purposes. Everything from Web development to cleaning up hi-res scans of photographs (BW and color) and art. I don't use it at my full-time job, so there's not really any production pressure. I'm starting to wonder if I can find a list of new features and major enhancements associated with each release in case I have a reason to upgrade. (The only time I've hit a barrier with v7 was discovering that its grayscale mode had a limit on what degree of bit depth it would handle.)
Unfortunately the Adobe info I've seen is far too wordy. I would prefer a simple table or list. Have not found one on the Web. Tips?
We're on version 14. There are too many improvements to simply list.
Try http://en.wikipedia.org/wiki/Adobe_Photoshop_version_history for a (still incomplete) list of the features added with each version.
Good advice from the previous posters, but I would like to point out two items:
Smart Objects and Smart Filters
Those have been significant improvements.
But you may want to consider whether you want the Cloud License that goes with Photoshop CC or a Perpetual License for Photoshop CS6.
The Cloud License seems to be perceived as odious by some …
And as you have not been a each-version-up-grader regular payments may not be in your interest at all.
If you download a trial version of CS6 be sure to install the CS6 updates, CS6 is not stable without them. Adobe introduce some nasty bugs in CS4 which have not been fixed todate. If you use Photoshop Automation be careful when using automated processes that add Adjustment layers. They may not always work as they should.
Somehow when I first searched Wikipedia it didn't pull up that link. Then you provided it; just what I was looking for! I also found an interesting older overview here ...
To cap it off, the c.pfaffenbichler and JJMack posts had excellent specific info -- Thank You.
