From the Iridient Website.
'Iridient Developer is a powerful RAW image conversion application designed and optimized specifically for Mac OS X. Iridient Developer gives advanced photographers total control over every aspect of their digital camera's output, yet still provides easy drag and drop batch conversion and access to basic adjustments for the casual user. Thanks in part to Dave Coffin's work on the open source RAW decoding program dcraw, RAW developer is able to support files from over 400 RAW capable digital camera models!! Note that although we do use portions of dcraw for decoding RAW image files, essentially the entire image processing pipeline is completely unique to RAW Developer this includes the demosaicing algorithms used for all cameras based on RGB color filters (which is nearly all of them), all color management operations, all other processing adjustments, sharpening, noise reduction and final file format conversion.'
