It’s a little bit more of an experimental post this week, something I’ve not done in a while.
This week I’ve been playing about trying to capture party poppers in the process of firing, using my Triggertrap. I bought a Triggertrap a while ago, but I’ve not had much of an occasion to use it. Its main outing for me so far has been timing some long exposures down by the river.
The idea came to me at a family birthday, which saw a bunch of party poppers being set off that I tried to capture manually with my own innate sense of timing, which is good but not that good. Realising I’d need some assistance, I grabbed a few of the party poppers to play about with later.
My first setup connected my iPhone to my camera and set the Triggertrap to sound trigger. This, it turned out, was folly. The act of firing a party popper happens way too quick even for the minimal delay in firing the shutter and all I captured was a bit of smoke. Back to the drawing board.
The answer lay in the Triggertrap flash adapter. The flash can fire pretty quickly compared to the shutter, so instead the way to do it was to connect my iPhone to the flash, still set for sound trigger, then pre-focus the camera and set it for a four second exposure. Make the room dark enough – much easier at this time of year when the sun devotes more of its time to keeping people in the southern hemisphere warm – and all you’ll see is what was illuminated for the split second the flash fired. This worked much better.
As you can see, the focus isn’t quite right – I need to work on my prefocussing, evidently. I also decided the background was a bit cluttered and so moved the camera a bit for a slightly neater frame (only slightly neater, I admit).
