Photolemur

Photolemur is designed to have the least human involvement possible. Behind the scenes, Photolemur analyses millions of pixels per second, identifying individual features such as trees, faces, foliage etc. and automatically makes enhancements which make your image stunning. As you bring in more images, every saved or shared photo builds a database of successful enhancements, and every non-saved image goes into an unsuccessful database. This ensures that all future enhancements are built on a record of success. Photolemur is constantly learning what you like and don't like. For the user, it's simple. Open an image in Photolemur, or drag an image into the application from anywhere on your Mac.
