Changing color levels produces red/cyan shift
« on: April 18, 2022, 08:50:23 PM »
I am trying to use the "Adjust Color Levels..." tool that you open by right-clicking on an image, but when I change all the values by the same amount (150 in my case) the image becomes dramatically Red. If I reduce below 100, then it shifts toward Cyan.

(See attached image)

Weirdly, the thumbnail shows the correct image, but not the large viewer.

What's going on here?
