Hi Alex,

Well, the only way I got user_mul to be applied was then no_auto_scale=0. I have always had no_auto_bright=1 and adjust_maximum_thr=0.0.

in Libraw::scale_colors() user_mul is copied to pre_mul if it is set. And then, I only see pre_mul used if use_auto_wb or use_camera_wb is set.

What I would need is to use the camera multipliers (i.e. 1.99,1.0,1.77,1.0, as defined by Canon for my camera), but no scaling done to the image.
