Hello

i have an issue when i add sharpening (which happens normally) and i click the highlight tool to check which areas are affected, it just show me white screen.

screenshot attached
Any help?

Could be I'm wrong about this, but I would not expect Sharpening to be something that can be Highlighted.

And indeed I see no change for Highlight when engaged. No white. No change at all. Which is what I expect.

Studio 20b1 for Windows.

Try to switch from A/B difference to Highlight B/W then again back to A/B, see if that help.

Also try to ad a new empty node at the end of your pipeline (very last node) and try add sharpness there, with highlight A/B difference activated.



@Jim, yes, sharpening can be highlighted, with Highlight A/B difference, it will show pixel-based changes too, so sharpening highlight A/B difference should show the difference where it is applied. Good way for sharpen only edges and smooth them with level and coring softness.

I know Sharpen Edges (which is a far more fully-featured tool) can show highlighting, and help you narrow down what specific frequencies are being affected by the operation. Soften/Sharpen and I think Texture Pop can do the same thing.

tried it and still just white screen

Ahh. That is a feature I'm unaware of.

A/B highlight mode works for sharpening. You are probably doing something wrong.

That's what I'm trying to find out, maybe someone faced the same issue and got to fix somehow

The highlight button a/b mode does not work if luminance in primariesis set to zero. As of R18.

As of R20.b.1 The highlight mode in color page is entirely broken. As is the wipe button which adds supers-saturation and contrast.i expect thi has a priority fix. But not yet I resolve 20.b.3.
