old script to run (possibly a python version problem), but have used dcraw
to process a couple of my images to tiffs with the same options as are used
in calibrate.py and these look very similar to those processed by darktable
with an sRGB input profile, but they are massively darker than those using the
Linear Rec 2020 RGB profile.
