Photo editing is all about making changes to the visual image, using your own aesthetic preferences to make the picture just that much better than the original. With some simple tricks in iPhoto for iPad, you can make that good photo better, and that great photo sing.
iPhoto has three tools that you can use to do just that. Brighten, Zoom, and White Balance. While the features may be fairly intuitive, it never hurts to point them out, as not all of us are intuitive in the same way.
