White balance seems broken on converted film negatives #6804

Closed AKADAP closed 1 year ago

AKADAP commented 1 year ago

Steps to reproduce Open a RAW image of a film negative Screenshot from 2023-07-29 15-36-18 Convert to positive Screenshot from 2023-07-29 15-39-05 Attempt to adjust white balance by picking a point that should be a shade of grey Screenshot from 2023-07-29 15-40-29 In this case, I chose the breast of a seagull. It may not be pure white, but it is not far enough off to get the results I got. On a side note, all of the sliders for white balance seem to work reverse of the way they are marked.

Expected behavior I expect the white balance to get better, not worse.

As of version 5.9, the Film Negative tool behaves differently and the documentation on RawPedia is outdated. The White Balance tool should be used to balance the color of the backlight. White balance of the film image should be set within Film Negative itself.
