[Autogenerated] Hello.

Welcome to the new Channel Fundamentals Course.

This is channel fundamentals and I am Daniel Smith.

I'm a visual effects compositing supervisor,

as well as a teacher and trainer for Nuke Channel nodes.

And their operations are the cornerstone toe understanding,

nuke and the core of compositing.

No other nodes air so useful and simultaneously the most misunderstood.

We will peel back the veneer and de mystify the way Nuke

operates on its channels and understand how,

why and when to implement them, to create better work.

Channels are the very building block of all images.

All images are made out of channels.

Each color channel is a representation of the light that a surface receives.

Each Alfa Channel represents the occlusion of light.

Each channel can be rearranged,

manipulated and utilized elsewhere in the composite

channels can be used in infinite ways.

The possibilities are everywhere.
