Is white balance mode set to “off” on your gradient layer?
(Sorry for the basic suggestion - I’ve been tripped up by that more than once!)
No issues. As I mentioned one reason I work in LR much more than C1 is the graduated filter tool vs C1 gradients which I felt were very poorly done because of the inability to correctly place a gradient with speed and ease. So I”m a noob at C1 gradients.
Thanks to your suggestion and little experimentation this turns out to be a design difference between LR and C1. In LR, global adjustments are just that. Lr really isn’t working on a layer concept like C1. so any global white balance adjustment affects everything on the image and any adjustment white balance affects the adjustment area, but global settings are still applied.
Now I’ve learned that C1 works differently, if you apply a white balance adjustment to a layer, that layer now has an independent white balance setting, and background adjustments apply only to areas not covered by the adjustment layer. I guess this sort of makes sense if you think of it in stacked layers. However, it seems strange that this doesn’t apply to other adjustments like exposure, saturation etc. Any adjustments to the background for nearly everything else applies to the entire image.
Personally it seems odd to me that it works this way, where most adjustments are global regardless if there is the same adjustment in a layer, but for white balance once the layer has a tweak to the white balance then the global one ignores that area. Maybe there’s a logical reason for it. I can’t think of one.
Easy enough now that I know what’s going on, just have to calculate and make the same WB adjustment on both layer and background.
