Photo Editor: the Guided edit mode
As the name suggests, the Guided edit workspace is packed with step-by-step instructions that guide you through a range of tasks—from tone fixes to far more complex processes such as panorama stitching and special type effects; there are 47 to be exact, presented in a beautifully designed and easy-to-use format. All you need to do is choose one of the effects and follow the step-by-step directions—easy!
Topics include Basics, Color, Black & White, Fun Edits, Special Edits, and Photomerge (a mini-application designed for stitching images together into widescreen panoramas, among other things).
