UFRaw (Unidentified Flying Raw) is a utility to read and manipulate raw images from digital cameras. It can be used on its own or as a Gimp plug-in. It reads raw images using Dave Coffin's raw conversion utility - DCRaw. UFRaw supports color management workflow based on Little CMS, allowing the user to apply ICC 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.

UFRaw has three modes of operation. As a Gimp (or Cinepaint) plug-in, you simply open the raw image with the Gimp and the UFRaw preview window pops up. You can also use the stand-alone tool ufraw to convert images interactively. For batch processing of images use ufraw-batch. Type man ufraw or ufraw --help for more information. (In MS-Windows you just click on the UFRaw icon or drag a raw image onto it.)

UFRaw has a graphical user interface, so you can simply open a raw file and experiment with the controls to see how they affect the image. Color management is a bit more complicated and is explained here. The purpose of this guide is to explain some of the more delicate issues of the raw conversion process. It is also useful if you want to have full control over UFRaw's default behavior. This is especially important in batch mode where you don't see your mistakes immediately.
