"If you shoot lots of indoor shots with flash, you've probably
seen "redeye". A camera can turn a perfectly ordinary person into a
zombie demon from Antares.
"Redeye is caused by light from the flash bouncing off someone's
retina at the back of the eye, and back through the pupil to the
camera. so you see an intensely red area the size of the person's
pupil. It's most obvious for pupils that are wide open: people who
have been sitting in dim light, and especially children since their
pupils open wider.
"Some cameras have a "redeye flash" mode, where they'll flash a
few times before the real flash to give the subject's pupils time
to contract. That helps, but it doesn't always cure it. And maybe
your camera doesn't have that mode, or it's too much hassle to set
it, or you just forget. What then?"
