UFRaw is a utility for converting and manipulating raw images from digital cameras. It can be used as a stand-alone tool or as a Gimp plugin, and images can be batch processed using the commandline interface. UFRaw reads most existing raw formats using Dave Coffin's raw conversion utility DCRaw, and it supports basic color management using Little CMS, allowing the user to apply color profiles. For Nikon users, UFRaw has the advantage that it can read the camera's tone curves. Even if you don't own a Nikon, you can still apply a Nikon curve to your images.
