Question

Merge to HDR quantization artifacts

I have a strange case of artifacts when using Merge to HDR Pro script in Photoshop CC.

I am using 32-bit mode for HDR, but the problem exist in 8 or 16-bit, too.

There is severe quantization of the image when 3 exposures are used, as seen on the picture (look at the trees, etc.).

The sample files with the exposures are attached.

Could anyone reproduce this?

Is it a bug in the script / can this problem be fixed?

Have you tried upgrading to version 21.0.0, released today, which includes in the fixed issues list a fix to banding with Merge to HDR

davescm, thanks for your answer!

No, i haven't yet tried version 21. Interesting coincidence!

I see that there is some bug report of problems with HDR, though not much info.

Probably, Merge to HDR is buggy and wasn't meant to be used seriously.

lambiloon, your answer is too ambiguous.

I think, you didn't pay attention that I'm using Photoshop and Automation>Merge to HDR script in 32-bit mode (without tone mapping).
