- Homework Statement
- Not sure what this field is for.
- Relevant Equations
- Layer 1 (Bottom) = 100% opacity
Layer 2 = 50% opacity
Layer 3 = 33%
Layer 4 = 25%
Layer 5 = 20%
I was given the above opacity levels for stacking photos to create an equal average of all photos as a single photo. Can anyone explain how this works? I suspect if I had 4 photos labeled A to D I could combine A and B first, C and D second, then AB and CD last, all at 100% bottom layer and 50% top layer. Now that seems equal but tedious and limited. How does the math work in the given method above?
