Re: [darktable-user] Darken or lighten unsharp areas?

2021-04-06 Thread Peter Szmulik
Hi Martin & Terry!

Thanks for your responses, and yes, the new feature sound very promising
and, as I understand it more general.

My use case would for example be a farmers field of, say wheat and trying
to take a photo of the first row of straws, with a narrow depth of focus,
uniform natural light - but with exactly the same color in the whole scene
(except sky) it makes it hard to separate out the first row of straws. In
this (and similar situations - crowds of people) it would be useful to be
able to either darken och brighten the out-of-focus areas I think.

Best Regards
Peter

Thanks Martin for this information. I just read the discussion and this new
contrast based mask refinement would have so many uses including possibly
Peter's request to lighten or darken regions based on sharpness. I feel it
would improve the denoising of areas such as skies with less impact on
detailed foregrounds for landscapes. I look forward to the implementation.

There’s a contrast based mask refinement on the way
https://github.com/darktable-org/darktable/pull/8597
maybe this might be a way to do this ...
