Lesson 2. Basic Compositing > What You've Learned

What You've Learned

  • You can attach nodes in the Node workspace in multiple ways, including clicking a node in the Tool tabs, right-clicking a node in the Tool tabs, and with the Tools menu.

  • The standard practice for layering operations that expect two input images is to connect the foreground to the first, or left, input and the background to the second, or right, input.

  • You can automatically organize your nodes by deselecting them all and pressing the L key.

  • The Over node expects premultiplied images.

  • The MDiv (Matte Divide) node undoes premultiplication.
