The app has a very nice split-screen mode so you can see the original photo and the edited version. I think it is best at removing objects from photos, but it does have a variety of other image editing tools like crop, saturation, sharpening and the usual array of editing features. In my testing, the app was intuitive and speedy. The GUI has been streamlined and the eraser tools now work with higher precision. Plus, it works smoothly with Mountain Lion. This version is faster and offers Lightroom and iCloud support. We reviewed version one of this app about a year ago.
Using a series of algorithms to determine what should be filled in where the object you removed was, it smartly and quickly repairs the photo with intelligent guesses about what to fill in. This little digital trick allows you to remove unwanted objects or people from an image.
It mimics the Photoshop content-aware fill feature that was introduced in Photoshop CS5. Snapheal is a cool, inexpensive (US$7.99) photo editor for the Mac with one very high-end feature.
