A Skin Tones slider that lets you color balance photos based on skin tone is built into the Color module. A Preserve Skin Tones control lets you continue to work with saturation and color corrections without distorting flesh tones. This worked well in testing.

The Effects module operates on a beautiful fan metaphor that offers all the program's effects in an easy-to-see animation. Artistic, Vintage, Aura, Black & White, Duotone, and Warm & Cool each have up to nine different effects that you can tap and choose or slide to adjust.

Using iPhoto for iOS on the iPhone is as easy or difficult as doing anything else that involves finger tapping and swiping on a small screen. The program does a creditable job of translating the controls on the iPad onto the phone. While icon-based interfaces are rarely optimal, the same exploratory sequence I went through above offers the same results on the phone. Amazingly, all of the complex features work equally in miniature form, and are easy to follow once you have the concept down.
