Inversion, cancelation, and HSL

Let's take a look at the rest of the formulas beginning with the one for the first inversion mode, Difference. Difference uses subtract. So we're subtracting the luminance levels of the active layer from those of the background layer and then we find the absolute value. So in other words, the result is always positive no matter what and that's why we end up getting an inversion result is because the numbers bounce back essentially. The composite luminance levels end up growing ever darker and then they bounce back and become brighter again. Exclusion, which is a very similar mode, it looks a lot like difference except it has lower saturation values, there is a lot of graze in the composite image.

It uses a completely different formula that's based on the screen formula. So we're taking A+B just as we do with screen and we're subtracting AxB which is that multiply, but then we're multiplying that multiply formula by 2 and that creates another kind of bounce back...
