Feb 20, 2015 at 23:13 comment added junkyardsparkle If there's some consistency in the time between when a phone turns on it's LED "flash" and when the exposure happens, it seems like you could design a sensor with an adjustable lag and tune it by trial-and-error... but you would still have to be able to tell the camera not to crank up ISO somehow.
May 29, 2014 at 3:23 comment added dpollitt @mattdm - You are correct. There are two issues with this answer. First of all the 430EX does not have an optical sensor(unlike the Nikon flash used in the video linked to). And secondly all of the smart phones I have tested do not seem to trigger flashes optically. What exactly the reason is for that I'm not sure but in any case it doesn't work.
Oct 12, 2012 at 2:45 comment added mattdm I don't think it will work with the iPhone, though, because it has an LED rather than a proper flash.
