Talk:Air-gap flash

Triggering discharges
Why is that sync rather than triggering? To my electronics engineer mind that is exactly the way the term trigger is used. Such as in triggering the timebase of an oscilloscope. I don't know a lot about photography and it is decades since I did any, but my recollection is that sync is setting off two or more flashes simultaneously. The setting off is still referred to as triggering, that could be done electronically with a cable between them, or it can be done with the slave detecting the light flash from the master. Or the triggering methods described in this article. SpinningSpark 22:12, 9 January 2016 (UTC)
