Burn

A variation on Divide, sometimes called ‘Color Burn’ in some programs.

This inverts the bottom layer, then divides it by the top layer, and inverts the result. This results in a darkened effect that takes the colors of the lower layer into account, similar to the burn technique used in traditional darkroom photography.

1_{[1_Darker Gray(0.4, 0.4, 0.4)] / Lighter Gray(0.5, 0.5, 0.5)} = (-0.2, -0.2, -0.2) → Black(0, 0, 0)

1_{[1_Light Blue(0.1608, 0.6274, 0.8274)] / Orange(1, 0.5961, 0.0706)} = (0.1608, 0.3749, -1.4448) → Green(0.1608, 0.3749, 0)

Darken

With the darken, the upper layer’s colors are checked for their lightness. Only if they are darker than the underlying color on the lower layer, will they be visible.

Is Lighter Gray(0.5, 0.5, 0.5) darker than Darker Gray(0.4, 0.4, 0.4)? = (no, no, no) → Darker Gray(0.4, 0.4, 0.4)

Is Orange(1, 0.5961, 0.0706) darker than Light Blue(0.1608, 0.6274, 0.8274)? = (no, yes, yes) → Green(0.1608, 0.5961, 0.0706)

Gamma Dark

Divides 1 by the upper layer, and calculates the end result using that as the power of the lower layer.

Darker Gray(0.4, 0.4, 0.4)^[1 / Lighter Gray(0.5, 0.5, 0.5)] = Even Darker Gray(0.1600, 0.1600, 0.1600)

Linear Burn

Adds the values of the two layers together and then subtracts 1. Seems to produce the same result as Inverse Subtract.

[Darker Gray(0.4, 0.4, 0.4) + Lighter Gray(0.5, 0.5, 0.5)]_1 = (-0.1000, -0.1000, -0.1000) → Black(0, 0, 0)
