DCS File Converter

Free software to convert proprietary Kodak DCS TIFF and DCR files to ordinary TIFF, PSD or JPEG files.
Supported cameras: DCS 3xx, DCS 4xx, DCS 5xx, DCS 6xx, EOS Series, NC2000, DCS 7xx, DCS Pro Back, 14N, and SCS 2000.Files from many of the cameras listed above can no longer be opened using Kodak's own software.

Kodak Photo Desk doesn't support the early camera models, and the DCS file format module doesn't work with Photoshop CS3.
