The researchers, Rob Jenkins at the University of York, UK, and Christie Kerr at the University of Glasgow, UK, have published a paper in PLOS ONE on extracting identifiable images of bystanders from corneal reflections. The researchers explained that at first they weren’t sure how well the images would turn out.
“Humans can recognize familiar faces from very poor images, so we knew that was on our side,” Jenkins told Phys.org. “At the time, we were not sure how much we would be able to recover from the eye reflections. As soon as we saw the first image, we realized we were on to something.”
In their study, the researchers used a high-resolution digital camera (Hasselblad H2D 39-megapixel camera) and illuminated the room with four carefully positioned Bowens DX1000 flash lamps. Then the photographer and four volunteer bystanders stood in a semi-circle around the subject to be photographed.
