Highpass filter bug?

Hi all!
When I use the highpass filter locally with a mask it sometimes happens that the module effects parts of the image that I haven’t masked. I think it effects highlights in particular and often blows them out.
Has any of you noticed this, too? Or is there something you can think of that I might be doing wrong?

Hey @Daniel2 welcome to our community!

It is hard to tell without a screenshot or two, or better, an XMP and raw file that reproduces the issue.

Here are two screenshots. One before applying the highpass module, and one after. I only masked the boy on the left.

Change the mode from “overlay” back to “normal”

Hi, could you click on the icon to show the mask(the square with a circle inside) and get a screenshot, please?

Edited: most probably is what @paperdigits says.

It’s really just the boy who’s masked :face_with_spiral_eyes: :blush:

Also, I don’t quite understand :)) If I put it back in “Normal” then I can’t use the module for sharpening, right?

If you want to use highpass in overlay blend mode, move it after your tonemapper, as it does strange things to the highlights otherwise, also in “out of mask” areas.

I have been using an old version of DT until recently. How do you move modules again?

It used to be Ctrl + Shift + dragging with left mouse button. But in recent versions it seems to work with only dragging too.

Is there a way to mark this question as solved?

You can change the title to include [Solved] but other than that we don’t really do that
