Neat Camera Trick Makes Falling Water Appear to Float Upwards

A couple weeks ago we shared an interesting video in which a speaker and Canon 5D Mark II’s frame rate were used to make water appear to be frozen in mid-air. This new video by YouTube user Brusspup takes the idea to the next level by making the water appear to travel upwards. He explains:

Fill a bucket full of water and place it about 5 feet off the ground. Place a subwoofer about 1 foot lower than the bucket. Run a plastic tube from the top bucket down in front of the subwoofer. Tape the tube to the front of the speaker. Then aim the end of the tube to an empty bucket on the floor. Get the water flowing from the top bucket. Now just generate a 24 hz sine wave and set your camera to 24 fps and watch the magic happen. Basically your cameras frame rate is synced up with the rate of the vibrations of the water so it appears to be frozen or still. Now if you play a 23 hz sine wave your frame rate will be off just a little compared to the sine wave causing the water to “move backward” or so as it appears. You can play a 25 hz sine wave and cause the water to move slowly forward.

This experiment has become quite a trend as of late — this particular video has been viewed over a million times in less than a week.

Sound Painting Photographs with Paint and Speakers

Photographer Martin Klimas, whose porcelain figurine photos we shared yesterday, has a series of photographs that look like 3D Jackson Pollock paintings. He spent six months photographing portraits of sound by playing music through a speaker that’s crowned with paint. Klimas dials up the volume and then photographs the paint coming alive from vibrations caused by the sound waves.

Triggertrap Lets You Trigger Your Camera with Anything You Can Think Of

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.

How Sound Effects are “Painted” into Hollywood Movies

Did you know that while cameras provide the things you see in movies, most of the sounds that you hear — aside from dialogue and music — are generated by Foley artists who reproduce everyday sounds with everyday things? Here’s an interesting behind-the-scenes glimpse into how award-winning Foley artist Gary Hecker “paints” sound over what’s captured with a camera.

Making Paint Dance in Slow Motion Using Sound Waves

Dentsu London, the same ad agency that recently experimented with iPad light-painting, was recently hired by Canon to create a commercial for the Canon Pixma line of printers. They decided to create super close-up and super slow-mo shots of paint dancing by using sound, and created a rig that spins around the paint super fast to create a sense of motion as they shoot at 5000 fps. As you’ll see from the video, this is a great idea for still photos as well.

The resulting commercial can be seen at the end of the video. It’s stunning.
