iPhoto For iOS Is A Bargain At $4.99
Ready to start editing your photos? iPhoto provides a lot of great tools, starting with basic ones such as auto enhancement and rotation. But you'll probably spend most of your time with the five tool icons in the lower left corner: crop and straighten, exposure, color, brushes, and effects. Effects, which iPhone cleverly displays like a paint-store fan deck, let you experiment with six filter sets: Warm & Cool, Duotone, Black & White, Aura, Vintage, and Artistic.
