Researchers studying the level of detail in modern digital photographs were able to pick out the tiny reflections of faces hidden in the eyes of the subject and accurately identify them.
Working with Christie Kerr, of the School of Psychology, University of Glasgow, Rob Jenkins of the University of York recovered the images of bystanders that were as small as 27 pixels across (1 megapixel is about a million pixels), said Fox News. Yet when presented to panelists in a face-matching task, observers were able to match the diminutive faces 71 percent of the time. When the faces were familiar ones, people recognized identity correctly 84 percent of the time, it said.
