Hard-coded values provided by the dcraw library embedded within RawTherapee.

The dcraw_matrix field in the camconst.json data file available in RawTherapee's installation directory.

Which profile is embedded can be checked with GIMP for example.Ī conversion takes place based on profiled information from either of three sources, in decreasing priority: sRGB) will be assumed linear, making them look brighter. This means that gamma-encoded files (e.g. Note that selecting 'No Profile' for non-raw files bypasses the embedded color profile and the working profile will be assigned. Applying no input profile is generally only useful for analytical purposes to show images in the camera's native RGB color space, or in extreme cases to prevent clipping of channels when the camera has recorded colors outside of conventional gamuts. No color conversion will take place and a unit transform of the image data is applied. RawTherapee's interface for choosing the input profile 1.1 No Profile There are several ways to apply an input profile. The input profile is applied to the image data at the beginning of RawTherapee's processing pipeline because most tools depend on it. Without a camera-specific input profile, accurate color representation is impossible. Elle Stone's article, DCamProf's documentation or How to create DCP color profiles.

Such a profile is the result of the analysis of how specific colors and tones are captured, processed and represented as raw data by the camera (for more details, see e.g. This conversion requires an input profile made specifically for the camera.
