If you use Photoshop Elements you might be interested in this handy little tool. Photoshop Elements+
Let me quote:
As you, probably, know, Adobe Photoshop Elements has not inherited all of the essential features of the full Photoshop. Some functions have been removed, while the others just stay hidden. The “surface” Photoshop Elements functions are quite sufficient for a beginner. As you advance, though, you may miss one or another undocumented function. Here “Elements+” will be of service to you.
It’s simple to install and there is a demo version available. It’s available for the PC and Mac versions, so if there are functions that you would like to use that have been supressed in Elements, give this a go. Of if you have an old version of Photoshop (like me) and choose to buy the far cheaper but newer Elements as either a replacement or another option, this may make it all less painful for you. I’ve not worked my way thru all the bits yet, as I am happy flipping between the two for now, using Elements where I can or full PS when I have to, but at some point I may just shelve PS7 and go full Elements.
On a side note, DS has downloaded The Gimp (Mac and PC), and loves it, says it is easy to learn as has near as full functionality as the current Photoshop does. I may get a tutorial from him someday and give that a go as well!
