dmstraker Posted September 28, 2020 Share Posted September 28, 2020 (a) Duplicate source image, Blend Mode: Colour Burn. Expected result. (b) Restart. Add adjustment to source image (eg Curves), Blend Mode: Colour Burn. Unexpected result -- It is partially inverted.. Should it not be as in (a)? Source and .afphoto images attached. colour_burn.afphoto Quote Dave Straker Cameras: Sony A7R2, RX100V Computers: Win10: Chillblast i9 Custom + Philips 40in 4K & Benq 23in; Surface Pro 4 i5; iPad Pro 11" Favourite word: Aha.

dmstraker Posted September 29, 2020 Author Share Posted September 29, 2020 Curious rider: To double check on another machine, I downloaded the jpg image and there was no problem. But the .afphoto still displayed the problem. Is this something to do with file size or rendering? The problem also appears on v1.9. For reference, the problem image is uploaded (suggesting it's not rendering). Edit: Further experiments show that the problem occurs in 16 bit but not 8 bit.

Staff Chris B Posted October 2, 2020 Staff Share Posted October 2, 2020 Hi Dave, For me, if I open that file up on retail, I see the issue. If I open it in the beta with OpenCL, I do not see the issue. If I open the file again without OpenCL in the beta, I see it.

Depends I guess if OpenCL is going to be the standard. But then if you can turn it off for whatever reason, the bug is still there.
