Title: Color Temperature Adjustment with Adjustment Brush
Post by: Robert Boire on January 12, 2021, 09:49:32 pm

I need to adjust the color temperature on part of an image.

First I quickly played around with the color temperature on the entire image and then noted the color temperature I need to be at for the part I am interested in.

Then I painted the relevant part of the image that needs to be adjusted. However the scale for color temperature with the adjustment brush is -100 to 100 (% ?, of what ?). Is there a way to relate this scale to an actual color temperature? Or do I need just to eyeball it?

I suppose you could create a brush preset for that, or take the image into Photoshop and use a photo filter layer.

Almost always this way, unless you have an objectively greyscale target in the adjustment area the could guide your adjustment.

Yes, you do this by eyeball. The plus/minus has no direct correlation to a temp value. Nor is that necessary when you consider that any CCT value like 5621K is a range of possible colors, not one defined color. The numbers don't matter; the color appearance does.
