I have a canon 600d that says it uses sRGB. How is this even possible without having the same spectral sensitivity spectrum as a standard observer? It is possible to define the matching functions of the camera for a set of known display primaries (as the sRGB ones) when the sensitivity spectrum is known. This I believe, and please correct me if I am wrong, means that I know where the locus of the camera lies on the sRGB colorspace and consequently on XYZ.
But I do not really know the transformation between the camera space and sRGB. Nor do I know the type of transformation.
My question is: what are the calculations involved in transforming the outputs of the camera sensors to provide an image in the sRGB space?
