The eyes are not just the mirror of the soul, they also mirror the world around us. Now, a UK team has found that today's high-resolution digital images are now so detailed, they can enlarge the eyes in people's photos and retrieve images of out-of-shot bystanders reflected on their corneas.
Combine this with the fact human beings are very efficient at recognizing faces, even from poor quality images, and you have the makings of a rich forensic resource for solving crimes.
In the past it would be reasonable to assume if you were the one wielding the camera, then you would not be in the picture.
But a new study published in the journal PLOS ONE is now turning this assumption on its head.
Lead investigator Dr. Rob Jenkins, of the Department of Psychology at the University of York, says:
"The pupil of the eye is like a black mirror. To enhance the image, you have to zoom in and adjust the contrast. A face image that is recovered from a reflection in the subject's eye is about 30,000 times smaller than the subject's face."
