Recording and Using Looks
Similar to the EIS curve, the Fast Start is useful when you want to make a real
statement at the beginning of a fade.
The Fast End curve can be used as a sort of exclamation mark at the end of a fade;
really asserting the final position. Think of a light fading out at the end of a long and
dramatic death scene.
