DODGE

DODGE

DODGE divides the canvas colour by the inverse of the new one. The results are light, and they are lightened most where the canvas is already pale.

Measured: (100, 150, 200) over (200, 100, 50) gives (255, 243, 232) — close to white.

BURN is its opposite.

The name stays English. Dodge and burn are darkroom words: a hand held to keep light off the paper, or one that lets more through. No Setswana for either appears in any source consulted, and coining a word here would coin one a child will never hear anywhere else.
