I shot some photos on a green lawn with a 5DM3 with WB set to shade and I used a WB target and when I bring the photos into LR, I use the eyedropper on the photo with the target, copy the settings and paste them onto the photo I want to fix. I make changes to the other sliders, though there still seems to be a bit much green in the skin tones. What tools should I look into for correcting this?
Are these RAW files or JPGs? If JPGs you are limited in what you can do to correct incorrect WB. Start shooting RAW or RAW + JPG.
They are RAW
Change the WB so the skin tones look right?
If you want to supply an exported DNG via dropbox more specific comments might be possible.
