This lesson focuses on the various types of channels and colours.
We talked about how to give a graphic alpha channels and how to make them combine.
We were able to separate and combine the alpha and RGB of an image by processing them separately.
We used: shuffle, erode (blur, similar to blur), copy, premult
We also talked about the different modes of colour and some of the processes and methods of handling them.
We know that nuke’s built-in colour processing is linera, but we can view the image in a different way. We can use rgb, or we can use the built-in colour gamut of some cameras. But they don’t change the data in this picture, they just change the way we look at it.
