We wanted to give people a full free introduction to compositing inside of Blender. For anyone just starting out with comp, there are a lot of things you won't know. How to use the different nodes, which hotkeys will speed up your workflow etc. But most importantly, the theory behind compositing. So if you've ever thought about picking up compositing, starting out with Blender can be a great way to get going.
