Brightness
Function
This function is simply a multiplier on the RGB channels. It differs from
Fade in that Fade
effects the Alpha channel as well. If you want individual channel control,
use Mult.
You can also use this to convert your image to a single channel alpha
image by using a brightness of 0.
