Using the triggertrap as a slave flash

Posted on November 24, 2011 by triggertrap in Triggertrap Product Info 12 Comments

That's... a pretty impressive sync speed!

I love my Canon PowerShot S95 – it’s an astonishing piece of kit in all manner of awesome ways. It has one small flaw, though: There’s no way to connect an external flash to this camera.

So I figured… Would the Triggertrap’s built-in light sensor be fast enough to trigger an external flash, based on the pop-up flash on the Powershot S95? It turns out that yes, it is…

When shooting with the pop-up flash engaged in fully manual, the Triggertrap syncs with the compact camera at speeds up to 1/640th of a second. That, ladies and gentlemen, is bloody fast indeed.

The below photo was taken at 1/640 second, f/8, and the flash you can see in the picture is triggered by Triggertrap, which, in turn, reacts to the S95′s built-in flash via its built-in light sensor:

This also illustrates why I love the Triggertrap: Some times, I’m just sitting around thinking about cool things to do with photography. I was working with my S95 on a small project, and was cursing my Canon Speedlite 580EX II because it couldn’t be triggered by the built-in flash on the compact camera. But then it dawned on me: Hey, I wonder if the Triggertrap could be of assistance…

And if I can come up with ways of using the Triggertrap that I had never envisioned, I can’t imagine what you guys are going to come up with, once it’s out in the wild!

    Wow, can’t believe this never occured to me. This means I’ll finally be able to use some flashes with my macro rig where my NEX-3 has now replaced my Canon 20D, the former of which can only use it’s included proprietary flash. Yes I know I could’ve used one of those optical hotshoe triggers, but with the large bellows that I use the chances of the flash on the camera getting to that trigger isn’t too likely. Can’t wait to get my Trigger Trap.

    FYI, to be useful, it has to be able to ignore the E/i-TTL preflashes that P&S cameras and DSLRs put out…they don’t always put out the same number of flashes too :-P

    Can you use the infra-red LED on TT to trigger the Canon flash without using a cable/hot-shoe?

      That’s… A great question! I don’t think so, at the moment, but I’m definitely goign to take a closer look to see whether we can make that work!

    Hello

    is the shutter speed faster from brambing on the hardware vs the iphone app? – the iphone fastest release is 1/15 of a sec – need something faster.

    Thanks

      It’s not a limitation in the app or hardware – it’s a limitation in the way the camera manufacturers allow the use of Bulb on their cameras. So, unfortunately, it’s the same for both.

    Is it possible to do this with triggertrap mobile too?

    How do I set a delay between the first flash and subsequent flashes? I keep getting over exposed pictures due to multiple flashes due echo’s.

    Thanks

    Andrew
