-a real life example of point arithmetic
-variety of blending modes build on concept of point processes
a bit about the setup
the final output is a pixel blend
-> screen capture + camera
Blending Pixels
-blend two pixels from two images: fblend(a,b)
For example
-average: fblend(a,b)=(a+b)/2 : lighter color
-normal: fblend(a,b)=b
