I have lights that that cause my teeth to look a bit orange sometimes. And I found a tutorial for how to whiten those up a bit. But it uses Color Corrector (Secondary) and that ALSO tends to change other things in the video, like bright spots on the side of my head or my eyes. So any change to make the teeth look whiter ALSO makes those other spots look weird.
Is there a way to tell Vegas (using Vegas Pro 20) to apply changes only to the area around my mouth and ignore anything else in frame?
