Kodak recently posted v4.0 of Photo Desk and v.5.01 of the firmware for the DCS Pro SLR/n, the DCS Pro SLR/c, and the DCS Pro 14n/14nx. Both Photo Desk and the camera firmware are available in version for Macintosh and Windows, and they are free downloads.
The most important new feature in Photo Desk looks to be a Lens Optimization Slider Control, which allows users to select the degree of compensation applied to RAW images to correct for hue shifts caused by certain lenses on the DCS Pro SLR/n, SLR/c, and 14nx. The Lens Optimization Slider works only with RAW images shot on DCS Pro cameras with firmware version 5.0 or higher installed. Photo Desk 4.0 also fully supports the EXIF 2.2 standard, and a new "Paste Settings/Paste Special" function allows more flexibility when applying RAW conversion settings from one image to others.
The full list of new functions in firmware v5.0.1 varies with the camera model, but a Lens Optimization setting has been added to the Capture menu of the DCS Pro SLR/n, the SLR/c, and the 14nx. (The 14n already had one.) There are also several bug fixes, and support for the Pretec 1GB MMC card has been added to the SLR/n and the 14n/14nx.
