    One thing I found interesting is!how red-eye reduction works - it pre-flashes you eye briefly, before the main flash. So your pupils constrict and light doesn’t reflect off the bottom of your eyes. Yes, you are part of the mechanism!

    Some strange kind of bio-mechanical symbiotic mechanism is that!

      But then your subjects relax their pose on the first flash and you have 1/2 the group start walking off by the time the 2nd one flashes.
