080 Transferring luminance between images

- [Instructor] Hi! This is Steve Wright welcoming you to this week's Nuke Nugget! It often happens that we need to borrow the lighting and shading of one image and apply it to another image. Here we'll look at a work flow that does that while giving you great control over the final look. So we're going to start with this clip here, and we want to take the sweater and replace it with various images, but we want to maintain all the shading and lighting and wrinkles that we see in the sweater. So here's the setup. We start by taking the background plate through a saturation mode. We want to take the saturation down to zero like this, so we have a luminance version of the image. Now, very important point! Nuke retains the luminance when you draw the saturation out; however, some software programs don't do that, so watch out! So from here we go to a Grade node and that will be used to restore the luminance, you'll see in a minute, it'll all get darker. Then coming over here, these are the…
