The Nero Multi Trigger is a nifty camera triggering device that can make your DSLR and external flash unit respond automatically to sight, sound, and motion. It has built in optical, audio, and laser sensors, allowing you to shoot everything from lightning flashes to balloon pops. There’s also an intervalometer for time-lapse photography. The device mounts to your DSLR’s hotshoe and is powered by a pair of AAA batteries. They cost $200 each and are available for both Nikon and Canon DSLRs from the NERO website.
Here’s an interesting video tutorial by Destin of Smarter Every Day that shows how you can capture amazing photos of guns being fired and their muzzle flashes. Here’s the “basic” idea: he uses a piezoelectric transducer to convert acoustical energy into an electrical pulse, which he sends through a pulse generator. The pulse from the pulse generator is used to trigger a flash and an high-speed exposure. This allows him to photograph guns at the moment they’re fired in the same way many people photograph lightning. Read more…
Back in June we reported that Haje Jan Kamps of Photocritic was working on a neat new universal camera trigger called the TriggerTrap. Since then, he has managed to raise a whopping $77,262 for the project through Kickstarter and is now announcing that the device has gone into production. The TriggerTrap can be triggered by pretty much anything you can think of thanks to its laser trigger, sound detector, intervalometer, and AUX-port. It’ll cost $125 once it begins shipping in February 2012.
We have a bit of a scoop for you today: there’s going to be a new Kickstarter-funded gadget announced on Thursday called the Triggertrap. It’s a pretty nifty universal camera trigger that can trigger your camera’s shutter with anything you can think of using a built-in intervalometer, a laser trigger, a sound sensor, and an Aux input that you can connect custom triggers to:
Think about it: You press your car horn, it takes a photo. Your phone rings, it takes a photo. The sun rises, it takes a photo. Anything is possible – and that’s why this camera trigger is so eminently hackable and exciting to experimental photographers all over the world!
There’s also a private sneak-peek of the Kickstarter video over on Vimeo. The password is TriggerTrap123. Read more…
When Eadweard Muybridge shot the first motion picture of a galloping horse back in 1878, he used 24 individual cameras placed 27 inches apart, using trip wires to fire off each camera one thousandth of a second after the previous one. With fancy high-speed camera rentals priced at thousands of dollars a day, YouTube member Destin came up with a Muybridge-esque technique for capturing a bullet flying through the air using an ordinary DSLR: he shoots a bullet for each frame and uses a fancy trigger to capture the bullet at increasing distances, combining the resulting images into a neat super slow motion video.
IT consultant and photo enthusiast Viktor Takacs didn’t have much success when he tried capturing lightning on camera, so he decided to build this fancy do-it-yourself trigger (which he named “Zeus”) that automatically snaps a photo whenever the photodiode detects a flash of lightning. He even built a knob into the device that can be used to adjust sensitivity. The demo above shows the trigger reacting to manually triggered flashes from a strobe.
Takacs has a detailed post that walks through how he created the device. You can also email him for the code used by the microcontroller.
