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

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

Re: [darktable-user] Darken or lighten unsharp areas?
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 ... > Am 06.04.2021 um 06:25 schrieb Terry Pinfold : > > > Hi Peter, > is there any program out there offering this feature and if so, what > would be the purpose of doing this?
