 In the process of rendering linear raw data to conventional RGB data (e.g.for storage into JPEG image format), color space transformations and rendering transformations will be performed.In particular, almost all standard RGB color spaces and file formats use a non-linear encoding (a gamma compression) of the intended intensities of the primary colors of the photographic reproduction; in addition, the intended reproduction is almost always nonlinearly related to the measured scene intensities, via a tone reproduction nonlinearity.
