This is an interesting app for the iPhone (and iPad). You can place color into a B&W photo. Actually, the app transforms your color photo into B&W. Then, wherever you touch the photo, you "wipe away" the B&W overlay, revealing the original color. You can move and enlarge the area you are working on for greater precision. Not bad for 99¢. I took a picture of my friend's bongo, and here's a picture of a child and birthday cake.
