Aperture combines the control and speed pros want for demanding photo tasks with the easy learning curve iPhoto users need to step up to an advanced photo tool. It has been fully optimized for the Retina display on the new MacBook Pro, letting you browse and edit high-resolution images with remarkable clarity and resolution. And with a new unified photo library, you can now move seamlessly from iPhoto to Aperture —  and back — without having to import, export, or reprocess your photos. Aperture is packed with innovative adjustment tools to refine your images, including a revolutionary Auto White Balance that uses skin tones to correct color casts, and a professional Auto Enhance that applies Exposure, Vibrancy, Curves, and more with a single click. It also includes powerful Brushes for painting image adjustments onto parts of your photo, and dozens of ready-to-use professional photo Effects.
