Red-eye in photo comes from the lighting and human eye biology structure. In bright light, human
pupils are small; in low light they can get really big. When you take pictures in a dark environment,
such as a room with dim lights, or in outdoor night scene, the human pupils expand and contract in
response to the low light exposure. When your camera’s flash goes off, it goes through the dilated
pupil and reflects light off of the blood vessels behind the retina inside the eye. It is reflected back at
the camera in the form of a distracting red spot. These spots are the ones you seen on your pictures.
How to reduce or totally avoid red-eye when taking pictures?
Activate "red-eye reduction" feature on camera When this is used, the camera fires a series of pre-
flashes to close down the pupils before the main flash is fired. When the picture is taken, the pupils
are smaller, therefore create less red spots on picture. This can reduce red-eye on photo, maybe not
totally avoid it.
Turn the lights on. Red-eye is worst in dark rooms, so turn on a light or move people to a brighter
area, the pupils become smaller and the red-eye is reduced.
Look away from the lens. Different camera works differently on the red-eyes issue. Compared with the
flash that pops up or away from the camera, a flash stays close to the lens produces more of a
reaction because the light directly hits the pupil. So to ask people look away from the lens, either
above the camera or to the side opposite the flash, can reduce the red reflection.
Get a removable flash. The best way to shoot without red-eye reflection is to move the flash away
from the lens altogether. This is only possible on cameras that have a hot shoe or other connection
that allows for the addition of a removable flash. This can be expensive, but worth investigating if you
are shooting a considerable amount of photos in red-eye prone situations.
