Ok, trying to figure out how to adjust WB on portions of a file. It's a TIFF (from HDR processing from RAW files).
I've tried the following:
-Create a Hue/Saturation Layer
-Select the areas I want to adjust
-Bring down the saturation on the blue channel
Unfortunately, when I do this, it adjusts blue for the WHOLE photo. I'm guessing I need to mask it but I have no idea how to--never used masks.
Can anyone point me in the right direction? I can't find anything online explaining this. All of the things I find are adjusting in ACR but not in CS6 itself.
Thanks.
