iPhoto

 A powerful set of Multi-Touch tools helps you perfect color and exposure, crop, straighten, and retouch images. Enhance pictures by adding beautiful, Apple-designed effects with just a tap. Or use fingertip brushes to apply adjustments exactly where you want them. In addition to posting photos to Facebook, Flickr, and Twitter, you can beam photos between your iPhone and iPad, stream photos and slideshows to your Apple TV with AirPlay, and use iCloud to publish photo journals to the web to share your stories with friends and family in a whole new way.
