Perhaps because a Luma mask adjustment took place first?. Have not hit the tutorials on this. All I know is when I applied
a keying effect to the MCU the woman's shirt which was green turned to a light brown and the still that was keyed in replacing the green CYC wall looked great. Her shirt had all the details of the original but was now in the brown family. I thought for sure I'd have to crop the shot to a close up on her face.
Can someone explain how to do this deliberately or point to a tutorial on line.
