This method allows most cameras to maintain the full function of electronic and mechanical communication with the normally mounted lens, for features such as open-aperture metering.Created by: Shankar Kumaraverage 67% panoramicpanoramic2438nightnight803high-speedhigh-speed792macromacro8486lens riddles » What is the easiest way to see this photo in 3-D?Use red and cyan glasses.

The iris plays no role in the effect, but the blue-eyed people have relatively low melanin in the fundus as well. Therefore, they show a much stronger red-eye effect, as the light passing fundus is not absorbed by melanin. The role of melanin in red-eye effect is nicely demonstrated in case of heterochromia (one eye blue, one brown): typically, only the blue eye displays the effect.Created by: Kantapat Rassameehard 54% blue-eyed peopleblue-eyed people4374brown-eyed peoplebrown-eyed people1297elderselders116there is no differencethere is no difference2268eyes riddles » Why do cats have vertical pupils?To better see in the dark.
