University of Glasgow creates 3D with singlepixel sensors, skips the cameras video

Fast payday loans For Every One

Most approaches to capturing 3D models of real-world objects involve multiple cameras that are rarely cheap, and are sometimes tricky to calibrate. The University of Glasgow has developed a method that ditches those cameras altogether. Its system has four single-pixel sensors stitching together a 3D image based on the reflected intensity of light patterns cast by a projector. Reducing the pixel count lowers the cost per sensor to just a few dollars, and extends the sensitivity as far as terahertz wavelengths. Real-world products are still a long way off, but the university sees its invention as useful for cancer detection and other noble pursuits. Us? We’d probably just waste it on creating uncanny facsimiles of ourselves.

I Needed That: Compilation Of Inspirational Videos Caught By Russian Dashboard Cameras

| Author:

russian-dashcam-hope.jpg

In these trying times we live in, I know it can be hard to imagine any hope for humanity that doesn’t involve blasting off into space and just starting over. But to remind us all the world isn’t doomed just yet, here’s a compilation video of positive, inspirational videos caught by Russian dashboard cams. There are people stopping and waiting for animals, drivers helping push each other’s cars out of the snow, and a whole bunch of people jumping out of their cars to help old ladies cross the street. I really encourage you all to take the five minutes out of your day to watch it. So the next time you’re wishing the world would just burn after reading some piece of depression in the news, remember: in Russia, right now — at this exact moment — someone’s getting out of their car to make sure somebody’s grandma gets across the road safely. And that’s a beautiful thing.

Hit the jump for the video, you really should watch it.

How Future Cameras Will Be Able To See In The Dark

| Author:

Canon's showing off a full-frame sensor that can see stars and turn moonlight into daylight .

To get a well-defined picture of stars, a photographer usually has to do one of two things: take a long exposure of a second or more; or crank up the camera’s sensitivity to a level that adds noise and distortion to the image. Today, Canon is teasing a full-frame (35mm-film-size) camera sensor that can not just capture photos in extreme low light, but video, too. The above clip was recorded in real time with nothing but starlight.

This next image show two video captures of the same scene, one without the new sensor's improved sensitivity and one with. The only illumination is moonlight:

Canon’s DSLR cameras are known for their low-light performance — it's one of the reasons so many filmmakers use the 5D series in addition to, and sometimes in lieu of, pro-grade video cameras. But this is something different and more specialized: “The newly developed CMOS sensor features pixels measuring 19 microns square in size, which is more than 7.5-times the surface area of the pixels on the CMOS sensor incorporated in Canon's top-of-the-line EOS-1D X and other digital SLR cameras,” says Canon, which means the total resolution of its images is likely much lower than a regular full-frame DSLR. Canon says that the first generation of this tech will likely be used in non-consumer applications, such as surveillance and “astronomical and natural observation.”

It's worth watching the whole demo video, though, because the sensor's effect is profound. It basically pulls off night vision without screwing with image color. It's hyperreal:

Sony's NEX3N and A58 cameras make an inperson appearance, we go handson

Alright, so this is definitely not the first we’ve written about about these two latest entry-level shooters from Sony. That said, we’re excited to finally get some hands-on time with the Alpha NEX-3N ILC and A58 SLT DSLR. To refresh your memory, the NEX-3N is set to sell for $ 500 with a 16-50mm power zoom, while the A58 will go for $ 600 with Sony’s latest 18-55m f3.5-5.6 kit lens. Although we only had a few minutes with each inside a section of New York’s Natural History museum, we’re definitely digging the new wares. Join us past the break for some initial impressions.

‘Helmet of Justice’ uses seven cameras to make a black box for bicyclists

| Author:

Chaotic Moon Helmet

Design studio Chaotic Moon is known for its work on the “Board of Awesomeness” and “Board of Creativity,” which push the simple skateboard into new region with electric power and thought control. Its followup takes on a somewhat various problem: giving skaters and bicyclists an antidote to their prone position on the roadway. The “Helmet of Justice,” demoed on CNN last week, was established in feedback to a hit-and-run that left Chaotic Moon worker John Poindexter injured with no idea what had actually happened. Its core feature is a network of seven cameras that offer a 360-degree view around the user’s head. When the helmet identifies impact by means of an accelerometer, it starts recording, theoretically capturing the accident– whether …

Nikon’s seven new Coolpix cameras bet big on huge zoom and Wi-Fi

| Author:

Nikon Coolpix S9500

Nikon was quiet at this year’s CES, announcing just the J3 and S1 interchangeable cameras, but apparently it was just biding its time: the company’s now announced seven new Coolpix cameras, essentially overhauling its point-and-shoot lineup in one fell swoop. At the top of the lineup is the new Coolpix P520 (the successor to the P510, which will still be sold), which offers a ridiculous 42x zoom, plus an 18-megapixel sensor and a 3.2-inch tilting LCD. The $ 449.95 camera also comes with GPS built in, plus support for Nikon’s WU-1a Wi-Fi adapter.

Big zoom and Wi-Fi are common themes with Nikon’s new Coolpix models, as is ruggedization. The $ 349.95 AW110 is shockproof to 6.5 feet, waterproof to 60 feet, and freezeproof to -14 degrees…

Metabones Speedbooster guarantees much faster EF lenses when mounted on NEX cameras

Metabones Speedbooster makes Canon EF lenses faster when mounted on NEX cameras

There aren’t a lot of lens adapters that catch our eye, but the $ 600 Metabones Speedbooster has numerous tricks up its sleeve that we could see it tempting a lot of major NEX camera users– like us. Huge words, but exactly what it purports to do is absolutely nothing short of mind-boggling. First of all, it adapts your Canon EF (full-frame) lenses to E-Mount, which is good enough since there’s still a scarceness of high-end glass for NEX individuals. However it improves: the Speedbooster additionally makes your lens larger by a factor of 0.71 x, shrinking an 85mm lens to 59mm, for circumstances– successfully making your NEX nearly full-frame. Other adapters can do some of that, but its final trick is the piece de resistance: enhancing the rate of a lens by a complete stop. That may appear impossible, however it evidently works by focusing the added light-gathering area of a full-frame lens to the smaller E-mount sensor location, turning an f4.0 lens into an f2.8 lens, for example. The adapter presumably raises sharpness on top of all that, and brings “auto-aperture, image stablization, EXIF and (sluggish) autofocus support,” for late design EF lenses, according to Metabones.

Hesitation reigns till we could scope it for ourselves, however the adapter came out shining on Philip Bloom‘s video and photo evaluates up until now, judging by his samples (below the break). The $ 600 cost will likely deter laid-back users, but light-deprived in the house shooters (like us) or those shopping for brand-new glass– who already have a bagful of EF-lenses– may take it like a sugar abuser to Trix. Metabones said they’ll begin shipping the Speedbooster this month, and will come out with MFT and Fuji-X mount options, together with support for lenses from Nikon and Leica, amongst others. Check the source to see how to get it, however the line types behind us.

CES 2013 Digital cameras roundup

CES is far from a top-tier trade program for the digital imaging sector, however that didn’t quit producers from introducing new models. Android returned to Polaroid’s booth with the underwhelming iM1836 ILC, Canon went with a square type element with its PowerShot N and Fujifilm introduced a more powerful version of the X100. Almost all of the cameras we saw at the program were created for consumers, with many choices can be found in under the $ 200 mark. Nikon and Samsung provided a couple of exceptions, however with Photokina finishing up this past September and CP + kicking off in simply over 2 weeks, there are plenty of various other locations for camera makers to introduce their higher-profile models. In the meantime, though, it’s everything about CES, so join us past the break for a more detailed consider some of this week’s most significant statements.

Nikon unveils J3 and S1, takes 73-point AF and 15 fps stills to entry mirrorless cameras

Nikon unveils J3 and S1, takes 73point AF and 15FPS stills to entry mirrorless cameras

Nikon plainly wishes to make amends for its unspectacular J2 launch late last summer season: it’s introducing not one however two 1 series designs that provide a more powerful incentive to go Nikon amongst lower-end mirrorless cameras. The 14.2-megapixel J3 and 10.1-megapixel S1 primarily obtain hand-me-down functions from the semi-pro V2, although that’s not always a bad thing. The leftovers provide them uncommonly precise 73-point autofocusing and an updated Expeed 3A processor that can handle 15FPS burst photography with constant focus– 3 times the frame rate of the J2 in the exact same conditions. Apart from their resolution, the major separators in between the J3 and S1 are the J3′s inclusion of a simple panorama mode and a somewhat larger ISO array for the S1, which starts at ISO 100 versus the J3′s 160.

Both brand-new bodies ship in February, when the S1 will lower the 1 system’s entry price to $ 500 with an 11-27.5 mm lens, and the J3 will have a suitably in-between price of $ 600 with 10-30mm optics. The shooters will soon be joined by brand-new lenses and accessories, too. A 6.7-13mm (18-35mm equivalent), f/3.5 -5.6 wide-angle lens and a 10-100mm (27-270mm equivalent) f/4 -5.6 telephoto zoom do not have conclusive release dates, however ought to respectively cost $ 500 and $ 550. Diving scuba divers who want a J3 or S1 for their trips will likewise get a WP-N2 undersea case in February, albeit at a $ 750 cost that’s more pricey than the cameras themselves.
