One of the drawbacks of the Sigma Foveon is the lack of support for RAW conversion by the usual tools. Files get processed by the Sigma software prior to being brought into Aperture.
Sigma has added a monochrome conversion to the newest version of Sigma Photo Pro. In keeping with Vincent Versace’s dictum to do RAW conversion for Nikon “the Nikon way”, I’m trying monochrome conversion for the DP2 “the Sigma way”.
I think it’s an impressive result, providing a level of image quality that can’t be reproduced by any other camera this size. The Leica ME has a different way of rendering as a system but also requires a good bit more of me as a photographer for image capture.
