This will work only in bright light where camera gain ("ISO
speed") will not change... Gain is similar to having variable
film speed - fine-grain/slow-film for bright light,
big-grain/fast-film for low light levels; when the camera
runs out of shutter speeds (at 1/60th, unless set at a lower
speed) and apertures (at wide-open), it starts to increase
CCD sensitivity with resultant weaker color and larger,
more visible "grain" size.
