Keylight: Color correcting the foreground
- [Instructor] Our last subject is to take a look at doing foreground color correction. So we'll move over here. Put that in the viewer, clear the property panel. Okay we'll hone the viewer. The whole idea about the color correction with Keylight is as you know, Keylight has absolutely no color correcting ability inside, so we have to do our color correction outside of Keylight. The way we do that is we set the output for final result, which is the pre-multiplied output. Don't forget you have the un-pre-multiplied option right there. Next, we'll add a grade node and don't forget that whenever you have an un-pre-multiplied image you have to tell it, so we're going to say un-pre-multiplied by the alpha channel, so now I'm ready to do my color correction. All I have to do is connect a merge node, hook up the background, we don't need this merge node anymore, and now I can color correct my foreground outside of Keylight prior to the composite.
