View Full Version : Synchronized shutters

29th March 2016, 05:55 PM
A few years ago I went to Italy to take some pictures at a friends wedding as a guest. It is traditional for the groom to wait outside the church for his bride and they kiss at before they process in. Weighed down with my Nikon FF kit, I captured the lippy moment.


A couple of years later he asked me to come back to do some shots of his first child's baptism and it was then that I got to see the full wedding album for the 1st time. The "official" photographer's shot seemed to be perfectly synchronized with my flash! (this is a dodgy phone photocopy)

Is it possible that his flash triggered yours remotely in some sort of slave mode? Given that an electronic flash lasts rather less that 1/1000 of a second it seems pretty unlikely that you were that well synched. Of course, if you were using a filament bulb (were hey called FP3s? I can't remember) that would increase the odds considerably :)

No! My flash was not triggerable like that. The other tog was using Canon and no flash. The timing was down to his shutter speed more than my flash....

If it was a full synchro flash (like the Olympus FL50 or the old F280) the flash duration would have been longer at about 200 milliseconds.

It isn't long but it increases the odds considerably over the normal electronic flash duration of less than one millisecond. (I think Metz quote a shortest flash duration of 1/40,000 second for their CL4 guns.)

I should add that focal plane shutters open for longer than the indicated shutter speed, so an exposure of (say) 1/250 second may last for about 1/60 second.
