LOVE IT!
Spent hundreds of dollars on Photoshop etc. when this is all I really need for now. Not sure if there are instructions somewhere but I just drugged a photo out of iphoto into it and started experimenting. I save them to my desktop when finished and then drag them from there back into iPhoto. May be an easier way. Just did a wedding over the weekend and am having way too much fun "coloring"/editing the photos w/ t his app.
