Description

Attached is a sensor noise profile for Olympus PEN E-P5.

Presets tested with darktable 2.2.5, Ubuntu 17.04. Seem to be detected correctly and denoise works fine.

Please include with darktable release, when possible.

Thank you!

The result don't look good. You can try to have more pixels between over- and underexposed

#3 Updated by Šarūnas Burdulis over 1 year ago

Thank you for checking. I might try making more samples, but — what are criteria of "results looking good"?

tools/noise/gen-profile was run without -C and didn't give any warnings.

#4 Updated by Šarūnas Burdulis over 1 year ago

Attached please find another noiseprofiling result with E-P5. Please include the profile with darktable release when possible.

#5 Updated by Stefan Schöfegger over 1 year ago

  • Status changed from Triaged to In Progress
  • % Done changed from 20 to 50

Thanks for doing the profiling again. The result look good, I will add them.

The criteria is the flat noise level for green channel which should match the ideal line.

  • Status changed from In Progress to Fixed
  • % Done changed from 50 to 100

#7 Updated by Roman Lebedev over 1 year ago

  • Target version changed from Candidate for next patch release to 2.4.0

#8 Updated by Joel Brandt over 1 year ago

I believe this profile will need an additional entry for ISO 100, per #11037, which I was bitten by again recently. Maybe the other affected profiles could also be patched in the next release?

#9 Updated by Šarūnas Burdulis over 1 year ago

Attached is presets.json with ISO=200 line copied to ISO=100 one, in case it's helpful.

Thank you.
