The Tuning controls

Tuning is the process of adjusting the matte density individually for the shadow, midtones and highlight regions of the image. I have made a special tuning test diagram here and the shadows are the foreground shadows which should be in this dark area down here, midtones around 0.18 or 0.2, and highlights up here. So the numbers here are designed to show us the brightness of the foreground elements while we are looking at our matte. So we will unfold the Tuning menu here and here are three adjustments for the shadows, midtones, and highlights.

Now the definition of what a midtone is, is set right here. The default 0.5 needs to be changed for Nuke to 0.18, because 0.18 is a 50% gray in Nuke's linear light space. If you had a very dark scene, you might move the Midtones value down a little bit lower and if you had a very bright scene, you might adjust it up a bit. But for the most part, a properly exposed scene, set the midtones at 0.18. Now we will pull a key, Shift+Alt+ Command, and now...
