Add

Function
This function adds color to the R,G, B, A or Z channels. This will add color to black areas, including those beyond the image frame, in case you move the image later on. Any correction occuring 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 will make your image completely black. If you add the fifth value, depth, you will effectively be adding a Z-channel with your add value to the image.
