Black tiles on the image #185

I see this sometimes but with this image and applying 3D LUT I get somes black tiles. When I resize the windows the tiles change but remain.

Let me know if I can something to provide more information.

Could you provide me the .pfi file and the LUT?

Thanks!

phweyland commented 5 years ago

I think I've got it. moving the exposure slider up in raw developer, the tiles appear.

Then it might be that the LUT module does not handle out-of-bounds values correctly...

Could you try to insert a "clip values" layer (it is found in the colors tab) just before the LUT, and make sure that bot negative and >1 values are clipped?

phweyland commented 5 years ago

Not enough I'm afraid

But is it normal to have clipped highlights after clip values layer ?
