Science textbooks say we can’t see infrared light. Like X-rays and radio waves, infrared light waves are longer than the light waves in the visual spectrum. But an international team of researchers co-led by Frans Vinberg, PhD, (left) and Vladimir J. Kefalov, PhD, has found that under certain conditions, the retina can sense infrared light after all.
Considering it’s been photographed I don’t think the human eye is a factor.
What does being able to capture it on film have to do with it?
When you take a photo, your eyes are not involved (apart from setting up the camera). The light comes from the source and goes through the camera lens onto the film or camera sensor, your eyes are not a factor at that point.
