Iridient Digital has released Iridient Developer 2.1 a major update to its critically acclaimed image processing software for Mac OS X. "This update features a total overhaul of the noise reduction functionality including three all new, state of the art, noise reduction methods along with optional auto noise adjustment levels based on ISO and other image parameters," says programmer Brian Griffith. The application now provides support for use of Apple's raw conversion libraries as an alternate raw conversion method and as a way to provide support for some unique camera models (such as Fuji's X-trans cameras) that Brian has not yet found the time to support with his own custom demosaic routines. A new monochrome conversion option, "Raw Colour Channel Mixer" has also been introduced, which provides direct colour mixing of the sensor colour planes direct from the demosaic process without any prior color conversion. Finally, the update adds support for 22 new camera models from a variety of manufacturers.
