lter results in the attenuation of visible light

while passing infrared unattenuated, and the

results can be catastrophic. The net effect of this

older lter is that red photosites are inundated

with infrared light while receiving less visible red

light. Similarly green and blue photosites color

lters are also somewhat transparent to infrared

light, and because they assume that the only light

they can receive is of the color of their individual

lter, they process infrared as if it was green or

blue light. This skews color reproduction and

results in pink, washed out pictures if a heavy

neutral was used. ...
