Description

I took several sets of images from this camera for noise profiling (dropbox links below). The images are taken wide open (f2) with the manual focus set to a minimum and at the widest zoom setting. Most images span the histogram, although I'm not sure if all ISO images span the entire thing due to shutter speed limitations. Hopefully at least one of these sets is sufficient enough to get good noise profiling results. I can take more if there are suggestions to get better sets of images.

I have not run the profiling script yet. Do I need to get darktable from git-master to get the noise profiling scripts? I currently just run darktable from Pascal's PPA on Ubuntu and I don't see these scripts available. I don't want the git-master version to accidentally mess up anything in my main database so I've been reluctant to use it.

@lebedevRI
Images can be opened now, thank you.

set 2 + 3 is not over exposed enough.
set 1 + 4 are usable, 4 looks slightly better.

I will add it in the next days.
