Compositing tips
Bonus Nuke scene files for this issue's tips article

To accompany his compositing tips this issue, The Orphanage's Matt Doll has provided three bonus Nuke files: blackLevels.nk and hueMix.nk illustrate his tips on matching black levels via separate RGB channels and on mixing colours between layers of a composite; while HSV_Keyer.nk is a standalone node, not discussed specifically in the article.
According to Matt, "HSV_Keyer is excellent for extracting practical elements, so I figured I'd be a good Samaritan and pass it on, as Nuke doesn't have this functionality built in."
