Got the file, thanks. Got the file, thanks. This is very special case: color.maximum is calculated from metadata for these files, this is just 0xfffc - black_level And after LibRaw::unpack() real data maximum is within this range. But on postprocessing stage, PhaseOne data are linearized using other metadata contained in file (complex process in phase_one_flat_field() call). After that stage, real (linearized) data values may have values above color.maximum -- Alex Tutubalin @LibRaw LLC reply
