Hi Piergiorgio Sartor,

I appreciate your expert advice so much that I wrote a script that
implements some of what you had suggested (BM3D to come later).

Please see the scripts attached to this thread, where prnuwash.py subtracts
a real camera fingerprint built from calibration images while fakeprnu.py
destroys the real fingerprint and replaces it with a synthetic fingerprint.

Which do you think is the better approach to improve moving forward?
