Bibble labs have release a new iteration of their great software. There was a need because of the release of a next generation of DSLR cameras: the Sony A100, Nikon D80 and Canon D400 / XTi.
That is what this software is for: you can take RAW images and Bibble lets you do anything you want with it to get the most out of you and your equipment. This includes compensating for any suboptimal things like lens distortion and image noise.

Super about Bibble is that they not only support Windows and Mac: they also have a Linux version. Suppliers that do so often know what they are doing and have an opinion about standardization.

And no, their software is not free of charge. However, with 70 or 130 dollars you can do things that would normally require much more expensive hardware.
