Framing reflected in Histogram about darktable HOT 3 OPEN

Frame isn't part of the image and shouldn't be included in the histogram

It is part of the final image. Otherwise it wouldn't be in the exported result...

There has been talk in the past of allowing the user to connect the histogram to the output of any module, which would allow you to bypass the framing module for the histogram.

Thanks for the context! I didn't realise that this was already discussed. And I do agree that the frame is the part of the final image, I should have used a different word to reflect the part of the image being modified/processed.

I am still not sure the histogram should reflect the frame as I personally don't see the value in it and find it rather confusing

I might be wrong in my assumptions/expectations, but to me, the histogram reflects the working range of the image. I use it to control/analyse/adjust the corrections applied. And the frame is not being impacted by any of the modules (at least I assume so based on a quick test). What is the value of reflecting it in the histogram then?

Let's say I add some exposure as I want to make the image brighter or check that colour corrections didn't introduce a tint, having a part of the histogram constant is not helpful and sometimes will hide the effect of the changes

Anyway, I reported this as it looked like a bug. If it's intended behaviour, I guess, I'll have to only apply framing after I'm done with corrections and switch it off if I need further adjustments. But it is definitely confusing and I don't understand what is the use case for this information on histogram

You can restrict the histogram to just a manually-selected portion of the whole image with the color picker module (in the left panel).
