AfterShot Pro uses OpenCL for the near-real-time rendering of colour adjustments and the like. While AfterShot Pro works to manipulate your JPeg (.jpg) images, it's real power lies in how well (and quickly) it can manipulate a variety of RAW photo formats, including those taken by my Nikon D5100, the RAW photograph .nfp files.

Installation was simple, with Debian-compatible 32bit and 64bit .deb packages (which probably run on Ubuntu as well), and an RPM package, available for download and a 30 day free trial.
I enjoyed my work with the software so far and I'm considering purchasing the software once my 30 day free trial is up. I've not taken a lot of photographs in the RAW format, but my camera can handle it so I may try to increase the number of RAW photos that I take. They use more space on my hard drive but they really raise the quality of the final product.
Check out the video of some of Corel AfterShot Pro's features and if you're looking for a solid RAW photograph editor, this may just be it.
