Join Steve Wright for an in-depth discussion in this video Spill suppression and color correction, part of NUKE Compositing: Zombies.
- So we have a preliminary key that looks…pretty good.…Again, we'll sweeten this up a little later.…But now it's time to lay in some spill suppression…and color correction.…So making sure we're talking to the Time Offset node…and not the Original Read node lets go get…from the Color tab the Hue Correct node.…Shift click so it branches off of course.…All right, so we'll do a shift command or control…sample of a large area of the green screen…in order to identify the hue of green…we want to spill suppress.…
And I'm going to use a combination of…Saturation and Green Suppression Curves.…So I pick both of those curves,…so I can move their control points to be right…centered on my target color.…Because as I make adjustments it's going to…move the darkened thing off the spot.…So, we'll start by taking the Saturation down.…That gets rid of some of my green spill.…Then we'll grab the Green Suppression Curve…and pull down on that.…
Neutralizing our green screen to an approximate gray.…Now we need to check our edges here…so I'm going to deselect my sampler there…
First you'll learn how to apply a quick key with Primatte, and enhance the zombie with realistic blood, red eyes, and fangs. Then, turning to the graveyard plate, you'll make a day-for-night color correction and add interactive lighting. Finally, you'll composite the key, plate, and effects and finalize the shot, using color correction and a push in effect. The process is broken down into easy-to-watch five-minute videos, rich in valuable VFX production techniques from compositing guru Steve Wright.
