Audio flashgun trigger

6 Nov 2009 5:01PM
This sounds daft. I want to photograph a guitar (mandolin, cittern, harp) string just after the finger or plectrum has left it. The twang, if you like. I've tried the movie mode on an Olympus SP560 etc and that is not good enough. Manually pressing the shutter release does not seem likely to work, mirror lag on my Canon may be predictable but I do not know how, so I thought a strum, into a microphone through some sort of black box . . .
Thanks for reading this far

Sounds like your looking for a sound trigger. I've used one in the past to photograph balloons bursting where the bang of the balloon bursting triggers the flash.

The best I've seen is a kit available from the US priced around $12 - do a Google for "sound trigger" and you'll soon find the site. I've been tempted to buy the kit in but a lack of knowledge of electronics has put me off.

Anyone else know if a ready-made trigger can be brought anywhere?

Thanks for that, I will start looking.

I think the kit mentioned is a bit of a bummer. It uses a piezo buzzer for a microphone. A balloon bursting may trigger the flash, but for high sensitivity work its a non starter. Look at my gallery and you will see 2 shots taken with my trigger. It is so sensitive heavy breathing will trigger it. Of course it is adjustable.

The trigger I use, goes back a long way. I first saw it a long time ago, long before digital . It was what started me designing gadgets for photo work. I could send you the circuit etc if you are ok with electronics.
