RawTherapee is a powerful raw image processing program. All the internal calculations are done in a high precision 32-bit floating point engine which facilitates non-destructive editing. Images are opened directly without the hassle of having to import them. Adjustments made by the user are immediately reflected in the preview and saved to a separate sidecar file. These adjustments are then applied during the export process, or can be copied (fully and partially) onto other images, thereby allowing easy batch image processing.

All aspects of RawTherapee are documented in the RawPedia wiki. There is also an active forum and IRC channel for interaction with the developers and other users.
