Kenji Kato visited the Quaketronics booth at the 2007 Bay Area Maker Faire. He brought his Nikon 10.5mm fisheye lens and Kenji took more great pictures which he uploaded to flickr.
Photo by Steven Noreyko
This high-speed photo is unusual because it wasn’t taken in the dark. While it is an homage to Doc Edgerton, unlike Doc, Steven was able to take this picture in a well-lit room. Usually high speed photographs are taken by triggering a strobe with the camera set to a long exposure time. Instead, Steven was able to capture the moment by electronically triggering the camera shutter. Here is Steven’s description of his setup:
Equipment:
The laser pointer was set with a clamp above the drop surface with the FlashKit trigger opposite, with the laser pointing directly into the photosensor (”eye”) of the trigger. The trigger was cabled to the Pocket Wizard Plus transmitter.
The camera is mounted on a tripod, pre-focused based on a test drop. The SB-800 strobe is hard wired to the camera using a PC sync-cord and set off to the frame on a stand. The remote trigger cable is connected between the camera and the Pocket Wizard receiver. You can and use a hard cable connection from the trigger to the camera if you don’t have Pocket Wizards. The flash output was metered manually with a flash meter. It’s set pretty low on the strobe - perhaps 1/16th of full power.
The milk is being dropped using a rube-goldberg setup with a small piece of rubber tubing, a stand and a clamp. I didn’t have a proper eye-dropper in the house at the time.
Since we are triggering the camera instead of the strobe, I was able to work with the lights on (exposure was f/11 @ 1/200 at 100 ISO). A few test drops helped me to place the camera focus point and position the laser. Ideally the milk drop would break the laser beam each time and trigger the camera (although this was not precise since my drop system was not so great). Adjusting the height of the laser from the surface and changing the delay settings on the FlashKit trigger would vary the results of the splash. I don’t have specifics on how high the laser was from the surface or the delay setting on the FlashKit trigger. At that point it was trial and error, and checking the capture on the camera display.

The speed of this strobe is amazing. This appears to be the fastest capture that I have seen so far using the Quaketronics flash controller. The lack of mottion blur shows that the flash duration is a short amount of time.
I didn’t know that you could get .22 pellets in green! Kalimistuk says that they come from Prometheus Pellets.

This photograph called “hard boiled egg” by kalimistuk is one of my favorites. His whole High Speed series is excellent. He shows what can be done with nerves of steel, a low-power sidearm, and willingness to clean up some spectacular messes!
Kalimistuk has also measured the speed of various flashes, and successfully modified a flash to make it faster. I will try out his mod, and if I can get it to work I will post it on the Quaketronics web site.
Balloon Waves, originally uploaded by Exocentric.
In this balloon popping photograph posted by Exocentric on the Flickr MAKE: Strobe Photography group there is a small amount of fine powder inside the balloon. I don’t know what powder was used in this picture, but others have reported good (but messy!) results with corn starch.
From the cleanliness of the red background, I would guess that this picture worked perfectly the first time!
This is a picture with a balloon in mid-pop. In high-speed photography, popping a balloon like the the ‘Hello, world!’ program in software. It is the first thing that you should try. It almost always works, and you get something that you can’t see with the naked eye.
Having taken many balloon popping photographs, I have come to appreciate the faces of the people popping the balloons. They are all unique and the pictures are not ordinary portrait poses. They are much more interesting, often capturing an intense expression.
This picture was taken at the Maker Faire in 2006 by someone who walked into our booth and used his own camera. You can do the same - we’ll be at the Maker Faire on May 19 and 20, 2007 at the San Mateo, California Fairgrounds. Bring your camera and give it a try!

Here is how it works:
High-speed pictures are taken in the dark, and sound triggers the flash. The camera is set to a long exposure time, but since the room is dark, the only light available is from the flash. If there is more than one camera, both cameras use the light from the same flash. In this picture, two cameras at slightly different angles share the light from a single flash, and capture the moment in 3D!
In a previous posting Espressobuzz tips off viewers to the StereoPhoto Maker software.
Learn about high-speed photography at the Edgerton Explorit Center in Nebraska, or see the Gallery.
Doc Edgerton invented the stroboscope and took many familiar high-speed photographs. The museum has hands-on exhibits, demonstrations, a summer camp, and the Oscar-winning 10 minute film short Quicker’n a Wink.
The Ultimate Golf Impact Shot, originally uploaded by Photosmudger.
The deformation of sporting goods is one of the classics of high-speed photography.
I was able to provide Photosmudger with a small amount of advice for this shot. The challenge was to minimize the delay between the impact and the flash. The speed of sound is the enemy here. My suggestion was to locate the microphone underneath the green, and to attach it to the golf tee. That takes advantage of the speed of sound in wood, which is faster than the speed of sound in air.
If I could only hit a golf ball, I would try this myself!
