What you'll learn

In this series of lessons, we'll learn how to use the Channel nodes inside NUKE to control our RBGA channels as well as any other channels we use during compositing. During this project, we'll learn how to use the Shuffle, Copy, ChannelMerge, Add, Remove, and ShuffleCopy nodes to do things like: move one channel from one to another, change many channels at the same time, add new channels, remove or keep channels, combine specific channels, and copy channels from one node to another. The channels system in NUKE can be an extremely powerful compositing tool if you understand the workflows and tools underlying it. Channels hold all of our image data, so knowing how to move, manipulate, and merge channels is an important skill for every NUKE compositor. Software required: NUKE 5.2 and up.
