Photograph of Single Atom Captured with a Plain Old Camera

Posted on by

The Engineering and Physical Sciences Research Council awarded a remarkable photograph its overall prize in science photography. The subject of the photograph? A single atom visible to the naked eye. Well, perhaps not exactly the naked eye, but without a microscope. In the picture above (click here to enlarge), the atom is that pale blue dot between the two needle-like structures.

You probably learned in school that you couldn’t see a single atom, and that’s usually true. But [David Nadlinger] from the University of Oxford, trapped a positively charged strontium atom in an ion trap and then irradiated it with …read more

Pipes, Tees, and Gears Result in Smooth Video Shots

Posted on by

It’s depressingly easy to make bad videos, but it only takes a little care to turn that around. After ample lighting and decent audio — and not shooting in portrait — perhaps the biggest improvements come from stabilizing the camera while it’s moving. Giving your viewers motion sickness is bad form, after all, and to smooth out those beauty shots, a camera slider can be a big help.

Not all camera sliders are built alike, though, and we must admit to being baffled while first watching [Rulof Maker]’s build of a smooth, synchronized pan and slide camera rig. We just …read more

Plastic Model Emulates the First Untethered Spacewalk

Posted on by

Here’s something really wonderful. [Dave Akerman] wrote up the results of his attempt to use a high-altitude balloon to try to re-create a famous image of NASA’s Bruce McCandless floating freely in space with the Earth in the background. [Dave] did this in celebration of the 34th anniversary of the first untethered spacewalk, even going so far as to launch on the same day as the original event in 1984. He had excellent results, with plenty of video and images recorded by his payload.

Adhering to the actual day of the spacewalk wasn’t the only hurdle [Dave] jumped to make …read more

Neural Network Electrocutes You to Take Better Photographs

Posted on by

It’s ridiculously easy to take a bad photograph. Your brain is a far better Photoshop than Photoshop, and the amount of editing it does on the scenes your eyes capture often results in marked and disappointing differences between what you saw and what you shot.

Taking your brain out of the photography loop is the goal of [Peter Buczkowski]’s “prosthetic photographer.” The idea is to use a neural network to constantly analyze a scene until maximal aesthetic value is achieved, at which point the user unconsciously takes the photograph.

But the human-computer interface is the interesting bit — the device …read more

Large Format… Videography?

Posted on by

Large format photography gives a special quality to the images it produces, due to the differences in depth of field and resolution between it and its more modern handheld equivalents. Projecting an image the size of a dinner plate rather than a postage stamp has a few drawbacks though when it comes to digital photography, sensor manufacturersdo not manufacture consumer products at that size.

[Zev Hoover] has created a large format digital camera, and is using it not only for still images but for video. And it’s an interesting device, for the way he’s translated a huge large-format image into …read more

Dead eBay Thermal Camera is an Organ Donor

Posted on by

[Damien] wanted to build a thermal camera. He was dismayed about how much a microbolometer costs so he salvaged one from a dead FLIR he picked up on eBay for 75 pounds. That’s about $100, and less than half what a new sensor costs. He selected one that didn’t turn on, which he hoped meant the Lepton 3 160×120 pixel microbolometer would not be the reason the camera failed.

Once it arrived, he pulled the pricey module, connected it to a breakout board and a Raspberry Pi. His gamble paid off; it worked fine. That wasn’t the end of the …read more

This DIY Turntable Just Got Freaky Fresh

Posted on by

Photography turntables are made for both the precise and lazy. Whether you are concerned about the precision of consistent angles during a photo shoot or you simply do not want to stand there rotating a plate after every picture — yes, it does get old — a lazy susan style automatic photography turntable is the ticket. This automatic 360° design made over at circuito.io satisfies both of these needs in an understated package. 

The parts required to make this DIY weekend project are about as minimal as they get. An Arduino Uno controls it all with a rotary encoder for …read more

High Speed Chronograph Looks Like Pro Gear

Posted on by

It can be hard enough to take a good photograph of a running kid or pet, and if we’re being honest, sometimes even stationary objects manage to allude our focus. Now imagine trying to take a picture of something moving really fast, like a bullet. Trying to capture the moment a fast moving projectile hits an object is simply not possible with a human behind the shutter button.

Enter the ballistic chronometer: a device that uses a set of sensor gates and a highly accurate timer to determine how fast an object is flying through it. Chronometers that operate up …read more
