Seeing depth through a single lens. Researchers at the Harvard School of Engineering and Applied Sciences (SEAS) have developed a way for photographers and microscopists to create a 3D image through a single lens, without moving the camera. Published in the journal Optics Letters, this improbable-sounding technology relies only on computation and mathematics-no unusual hardware or fancy lenses. The effect is the equivalent of seeing a stereo image with one eye closed. That's easier said than done, as principal investigator Kenneth B. Crozier, John L. "If you close one eye, depth perception becomes difficult. "If your viewpoint is fixed in one position, as a microscope would be, it's a challenging problem.
" Offering a workaround, Crozier and graduate student Antony Orth essentially compute how the image would look if it were taken from a different angle. "Arriving at each pixel, the light's coming at a certain angle, and that contains important information," explains Crozier. Bigshot DIY camera aims to teach kids tech basics. 5 August 2013Last updated at 18:40 ET By Leo Kelion Technology reporter Bigshot's creator hopes children will learn from first building his camera and then sharing photos A DIY digital camera designed to teach children about how the tech it uses works has been launched in the US. Owners of Bigshot's device need to assemble its parts in a specific sequence to make it work. An online guide explains the science behind them. It has been developed by a US computer science professor who used funds from Google and the US Department of Defense to develop the kit. He aims to offer an alternative to other programming-focused projects.
"It's about getting kids' hands dirty," Bigshot's creator, Prof Shree Nayar, told the BBC. "We describe concepts that children would normally encounter at college, but try to make them accessible even to an 8 or 10 year old. Owners of the camera must assemble its parts in the correct order to make it work One of the team behind the budget PC welcomed the news.

If humans could evolve faster, we'd have grown retractable 30-foot long arms by now. Why? So we could take pictures without having to stand right next to our cameras. With The iPhone Shutter Remote you can take pictures with your iPhone from up to 30 feet away without super stretch arms! It's a pocket-sized remote that lets you shoot photo and video via Bluetooth.
The iPhone Shutter Remote is perfect for getting group photos or self-portraits without having to run back and forth to your iPhone. You've always wanted to play with that long exposure app, but you could never quite get your hand to hold still for long enough. Not to mention, you can make that stop-motion you've always wanted to make! 30 foot arms? Lytro. Helmet Cam Review: GoPro, Vholdr, Drift & Liquid Image - Bitness.com | Geek to the Core. I’m a big fan of capturing moments on film and reliving them just after the fact and years down the road.
I have the whole saga of getting married on tape starting with the proposal and on through to the honeymoon (easy, I’m talking about the snorkeling in Maui and the helicopter ride in Kauii). This December a couple of friends and I hit Snowbird for some early season pow and caught it on tape using the Vholdr CountourHD and a GoPro (link). It was a good way to capture some side-by-side comparisons and left us wanting more (powder and side-by-side comparisons). From these tests, one of the most obvious differences was how important field of view is. With a smaller field of view you have to do a much better job of staying focused on the subject your recording (less margin for error).
The GoPro did a better job here than the Vholdr. Bitness reviewed the GoPro as far back as 2007 and a few years ago the Vholdr CountourHD. Both Vholdr and GoPro have made improvements since our first tests.
