I tried Easy Photo and like it. Also on their website are 2 additional giveaways, one for HDR Projects and one for Photo Buzzer. This last program is very similar to Easy Foto, they both let you easily try different filters for many many variations from the original picture. Both are easy to use, both can be controlled manually. Changes always start from the original pic with no way to “stack” them unless you make a change, save it, then add the next change (might need to load the saved file before adding an additional change). So there’s no Undo — it’s really not needed. And since I just downloaded, registered, installed and activated 3 of their programs in a few minutes, I can tell you the process is not so complicated and it’s the same every time.
