Description

Hi,

I tried to post these to the darktable-dev mailing list after being advised to do so on the IRC channel -- but after 12 days without a reply, I try reposting them here. Sorry for the inconvenience of a double-posting.

Attached are noise profiles for the Olympus OM-D E-M5 Mark II camera, generated using the 1.6.8 tools (as that was the current version when I did the profiling). There are two sets of ORF (raw) files, but I was unsure how to combine the results of the profiling -- average the values in presets.txt? I'll leave that to you pros :). In addition to the generated archive of files, I attach the output of the gen-profile script. Please let me know if there is anything I can do to improve on these profiles, or any other measurements that would be advantageous to the use of this camera with darktable.

In case you need to rerun the profile with different tooling or inspect the original data to judge the quality of the base images, I've uploaded the ORFs to dropbox (and they'll stay there until the noise profiles have been merged or I need the dropbox space): https://www.dropbox.com/s/5ngbpgwqey7c06b/raw-files.tar.gz?dl=0

All the best,

Stein Jakob

History

#1 Updated by Pedro Côrte-Real about 2 years ago

Both profiles looked similar and the higher ISOs didn't look all that good, but since the source images looked fine it's probably the best we can do.

#2 Updated by Pedro Côrte-Real about 2 years ago

Actually we have a way to keep both sets for future use even if right now we only use one. Added in this commit:
