Add

Function
The Add function adds color to the R, G, B, A, or Z channels. This adds color to black areas, including those beyond the image frame, in case you move the image later. Any correction that occurs outside of the DOD can be corrected with the SetBGColor node. Shake’s color is described in a range of 0 to 1, so adding -1, -1, -1 makes your image completely black. If you add the fifth value, depth, you effectively add a Z-channel with your add value to the image.
