Very simple, the red eyes are due to the pupils being wide open cuz of the dim ambient lighting. There's definitely not enough time for the physiological adjustment to take place during the single flash (even less, before exposure starts) but the sequence of weaker flashes is calibrated so that typically folks eyes will have adjusted to a greater brightness. This makes the pupils tighter by the time exposure commences. Also, I find the weaker flashes less annoying and, obviously, the actual "real" flash isn't nearly as annoying since the pupils are tighter. I think it's better, so long as the subjects aren't misled by it; before shooting, tell'em to count the flashes.

If ya wanna know whether to use it then, before shooting, go squint into the folks' eyes to see how their pupils are...

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.

We have been online since May 2000, and aim to be the best place to find and share science-related content of all kinds.

Share the love!
