IR filtering

Forums Imaging Infrared; friend or foe? IR filtering

Callum Potter

If you use refracting optics IR will focus at a different point to the visible – so will lead to blurry images.

With a reflector this does not happen. But the IR will still be detected (silicon detectors tend to be more sensitive to IR than visible light), and cause the colour balance to be off (usually appearing much redder).
But that is something you could correct in photoshop (or whatever…)
