yellow corner in back-lit silk showing – HELP!!
I shot a single subject against a back-lit silk. Worked great, except for one thing: In the lower corner of the mid-shot the screen was slightly under-lit and shows through as a faint yellowing, mostly in the lower-left, as you can see in the screenshot. (This didn’t show up on the camera LCD or monitor at the time).
or try this if the embed pic didn’t work: https://i213.photobucket.com/albums/cc117/orcasea/Image2.jpg
I need to try and remove the yellow, change to white – SOMETHING! To fix this. There is movement of her arms in the corner, and honestly, I am not highly familiar with making traveling mattes, although I can easily handle a relatively simple process that includes feathering into the existing white. If I can easily matte out just the bulk of the most noticeable yellow with a wide feathering band that would be great.
I am concerned about a color change process, because the tone & shade of yellow is also present in her hair and varies so much I would have to somehow select a range.
I am using Vegas 6.
ANY suggestions would be great!!

I would use the Color Corrector (Secondary) to select the yellow and map it back to white. It should work fine since she is wearing black at the bottom of the frame. You are right about the yellow in her hair. For that I would mask the FX. To do this, duplicate the track and use the Mask tool in Pan/Crop on the top track to make a large mask around the affected area. Then apply the secondary color corrector to the top (masked) track only. This should allow the top of the uncorrected lower track show through so that her hair won’t be affected.

Thanks, John, you’re a lifesaver.
Will activating the mask function on the dominant video track automatically make the mask exclusive (or inclusive, as the case may be)? Or do I need to somehow indicate that? More simply, how does it determine whether I was to retain what’s in the mask boundaries or retain what’s outside of the boundaries?
Thanks!

In the Mask properties on the left under Path you can change the Mode to be Positive or Negative. The default is positive which is includes everything inside the mask which is what you want.
