if it's possible to access (RGB?) data before writting to JPEG (or even better, before quantization to 8 bit).
it is. you have the RAW buffer, (10-bits) depth But I think that before doing your tonemaping, you first would have to handle the RAW processing (bayer pattern, apply the color matrix, white balance)...that's not easy AT ALL!!
But the buffer is available after RAW processing (bayer, color matrix, white balance)? If yes, it is still 10 bits? or these processes already quantize to 8 bits? I thought the quantization process is the last step before saving to jpeg.
