Frame Averaging

One of the exercises that we went over at LEVA was Frame Averaging. As a quick follow-up, I wanted to post the opacity numbers from the different exercises.

Blending two layers: 50% top, 100% bottom.
Blending three layers: 33% top, 50% middle, 100% bottom.
Blending four layers: 25% top, 33% next, 50% next, 100% bottom.

Are you beginning to see the pattern. It's easier to figure out the numbers if you think of the fractions: 1/n ... or for the example of five layers ... 1/5, 1/4, 1/3, 1/2, 1/1. The percentages work from smallest on top to 100% on the bottom.
