While most 14-year-old boys are hooked on things like video games, Laurent V. Joli-Coeur is busy using astronomy and photography for crazy science projects. A few months ago, he had the crazy idea of photographing a shadow caused by Jupiter’s light. He then spent 7 hours building an instrument to do so, and used a Nikon D700 and 60mm Macro lens lent to him by Nikon to capture the image:
I took three photographs to prove that Jupiter could indeed cast a shadow. The first one, a five minute exposure at ISO1600 with an in-camera dark subtraction, was taken to photograph a shadow: the results were conclusive. Indeed, after stretching the image in Pixinsight, the gnomon’s shadow was clearly visible on the projection screen (a gnomon is the object that creates the shadow on a sundial). However, this wasn’t enough to prove it was Jupiter’s. The second exposure was taken to prove that the light causing the shadow came from the sky, not from the instrument itself: I slightly moved the mount in right ascension, expecting the shadow to move sideways… And it did. The third and final exposure was taken in a region of the sky far away from Jupiter. As the last image showed no sign of the gnomon’s shadow, I concluded that the only possible explanation for the shadow in the first two images was Jupiter!
As far as Joli-Coeur knows, it’s the first photo of a shadow cast by Jupiter ever made. You can find a more detailed account of his experiment on his blog.
We’ve featured special gloves and mittens designed for photographers before, but what if your camera uses a touchscreen instead of physical controls? Here’s a video by Make’s Becky Stern showing how you can sew some conductive thread into your glove to make it compatible with capacitive touchscreens.

Photographer Tyler Card‘s uber-creative Nikon DSLR costume was the talk of the photo world this past Halloween. If you’ve been wondering how he managed to make a fully functional giant DSLR, you’re in luck: Card has written up an extensive tutorial explaining how it was done:
[...] it really takes pictures, and comes complete with LCD display, pop-up flash, and shutter release button. I built this entire costume in one week, for only $35 dollars (excluding the cost of the camera equipment and laptop), with materials located at any local hardware store.

A few weeks ago, Brooklyn resident Katie O’Beirne did a weekend project in which she left a disposable camera on a Prospect Park bench with a note asking passer-bys to snap a photograph. After getting the film developed and finding some cool photos, O’Beirne decided to continue with the project, leaving disposable cameras in a number of other spots around NYC. The resulting photographs can be seen on a Tumblr page she set up called “new york shots“.
Earlier this month we shared a hugely popular post on transferring a photo onto a block of wood. Well, the same technique can also be used to create a canvas print. All you need, besides the stretched canvas, is some gel medium and a photo printed with toner (e.g. made with a laser printer or photocopier). The gel medium is used to “steal” the toner from the paper, and once the paper is rubbed away, the print remains. Check out the full tutorial over on A Beautiful Mess.

P.S. Be sure to check out the wood transfer tutorial if you haven’t seen it already. It’d make for a neat gift for the holidays!
Artist Jonathan Keller Keller first started taking a self-portrait of himself every day starting in 2000, and later created a time-lapse video showing eight years of his life passing in less than two minutes (similar to Noah Kalina’s famous everyday video). What’s neat is that Keller maintains a directory of other similar photo projects out there. All the projects either deal with the passage of time or the obsessive documentation of something.
Examples include the Golberg’s yearly family portrait project done since 1976, the Brown sisters photographed every year for 25 years, and Ellie Harrison’s documentation of everything she ate during an entire year.
