ChocoFlop: CoreImage Photo Editing
ChocoFlop is an image manipulation program based entirely on Apple’s CoreImage technology which takes advantages of the processing power in your GPU (graphics card). It’s a very lightweight program and has the ability to apply filters in real time, with no long term damaging effect to your respective image. Chocoflop takes advantage of CoreImage’s built in support for many file formats, as well as layers, masks, selections and paint tools. It even features the ability to filter high-resolution HDR images at 128 bits per pixel. It is built to have no learning curve for Photoshop users and features many of the more obscure abilities of CoreImage, such as rich text layers.
All in all, if you are looking for a lightweight, but comparably powerful photo editor, ChocoFlop is a good choice. Keep in mind, ChocoFlop is still in alpha and can become unstable, though I personally had very few problems. ChocoFlop requires Growl as well as OS X 10.4, and is available as free download.

Core Image is the best. However, I like to stick to the developer sample app “Core Image fun House”.
