A prototype for a new DSLR add-on is poised to bring plenoptic capabilities to consumer cameras. The KaleidoCamera is designed to sit between a standard DSLR's sensor and lens. A diffuser splits light passing through the lens into nine different beams, each passing through a filter before it reaches the camera's sensor. Click through to read on about this prototype's capabilities and potential applications.

Photography has been around for almost two hundred years, but amazingly, it's only in the past couple of decades that it has gained widespread acceptance as an artform. These days, images by significant photographers command very high prices. But just how high is 'very high'? Internet community FreeYork.org has published a list of the ten most expensive photos ever sold. Click through for the list.

Hasselblad has unveiled a rather familiar-looking compact camera - the Stellar. The very RX100-esque compact offers the same 28-100mm equivalent Zeiss-branded zoom and 20MP 1"-type sensor as the Sony, but comes with a substantial hand-grip made from a choice of exotic materials and, we suspect, a significantly higher price tag.

It's not uncommon for photographers to feel much more at ease behind the camera rather than in front of it. Duo, a concept from Chin-Wei Liao, a Korean design school graduate, aims to transform the person behind the lens into photographer and subject simultaneously. Each half of the Duo is an individual camera. Assembled as one unit, pressing the shutter will record an image while capturing a picture of the person using the camera.

In the meantime, you can read more about the WG-3 GPS after the link.

A good summer photo project doesn't necessarily require a lot of expensive equipment, just a camera, an idea and the persistence to see it through. Chances are you've already got everything you need to kick off a photo series of your own. At DPReview we're always looking for new and interesting photos on the web and lately we've noticed a lot of inspired projects. Some are fairly laborious, while others take a simple idea and run with it. Check out these projects and why not get started on your own?

Panasonic has announced the Lumix DMC-FZ70, a 16MP compact superzoom with a 60x optical zoom that more than doubles the zoom reach of its 24x FZ60 predecessor. Spanning the equivalent of 20-1200mm, the FZ70's zoom lens has a maximum aperture range of F2.8-5.9 and is claimed to be both the longest and widest in its class. The FZ70 effectively replaces the FZ60, but the constant-F2.8 Lumix DMC-FZ200 remains in the lineup.

Panasonic has announced the Lumix DMC-XS3, a budget zoom compact camera that's just 14mm thick. It sports an optically-stabilised wideangle 5x zoom lens (24-120mm equivalent), a 14.1MP 1/2.3" High Sensitivity MOS sensor, and can record Full HD video in MP4 format. It includes a range of Creative Filters which can be applied either during or after shooting, and can also be used when shooting panoramas. The XS3 appears to be a Europe-only release, and will be available in September at a price of £119.

We've just updated our preview of the Sigma 18-35mm F1.8 DC HSM with lens test data, courtesy of DxOMark. This lens has generated a lot of excitement as the fastest zoom ever made for SLRs, but the big question is whether its speed comes at the cost of optical quality. We've looked into this by comparing the 18-35mm to some current benchmark designs - and the results may surprise you. Click through to read all about it.

Sensor maker Aptina has given more details of its Clarity+ technology that it claims will offer a 1EV improvement in sensitivity over conventional sensors. The company believes it has found a way to use clear pixels to capture more light while retaining the image quality of a standard Bayer sensor.

Toshiba has announced the Exceria and Exceria Pro ranges of SD cards - the first to conform to the UHS-II standard and the fastest SD cards yet announced. The Exceria Pro cards will be available in 16GB and 32GB sizes from October 2013 and will offer read/write speeds of 260MB/s and 240MB/s respectively. 32GB and 64GB Exceria series cards offering the same read speeds but half the write speed will follow a month later.

Engineers at Tokyo University's Ishikawa Oku Laboratory have come up with new technology to track extremely fast motion. Their new system - which uses 'Saccade Mirrors' for pitch and tilt, a 'pupil shift system', and very fast image processing - is able to keep even the quickest subject in the center of the frame at all times. According to engineers, the initial application for this system could be to capture video at sporting events. They expect it to be market-ready in about two years. Follow the link for a video demonstration of this intriguing new technology.

Online product reviews are a huge part of our lives these days, and often, they're the nearest thing we get to a 'hands on experience' before we buy something. But how do we know they're honest? Dishonest reviews are a serious problem for retailers (and indeed for content websites like dpreview.com) and a team at the Massachusetts Institute of Technology has been investigating why people are driven to leave reviews of products that they haven't actually used. Their findings might just surprise you. Click through to read more.

Does it have any place in the Micro Four Thirds user's camera bag? Click through to find out.

Today Nokia unveiled the Lumia 1020, its flagship 41MP camera-centric smartphone for Windows Phone 8. Aimed squarely at photo enthusiasts, the Lumia 1020 employs a large and extremely high resolution 41MP imaging sensor that we first saw in the ground-breaking 808 PureView. However, the 1020 has the decided advantage of running on the Windows Phone 8 platform instead of the end-of-life Symbian OS. Our sister site, connect.dpreview.com is at the launch event in New York and has published a detailed hands-on look at the new phone. Click through for more.

In the aftermath of Andy Murray's historic victory at Wimbledon 2013, Nikon UK has been explaining how its cameras were used in a robotics setup to capture images from unique angles during the championship. The system was developed in partnership with Mark Roberts Motion Control, and operated by photographer Bob Martin. It used a Nikon D4 mounted on the roof above Centre Court, with 200-400mm and 80-400mm lenses. Click through to see some of the resultant images.

So-called 'blimp' cases are designed to greatly reduce the sound of a camera's shutter, making it safe to take record shots during filming for TV and movies. Typically, commercial blimp cases cost upwards of $1000, but pro photographer Dan Tabár made his own using a Pelican case, some ABS pipe fittings, a wireless shutter release, and other simple parts sourced at a hardware store, for around $80. Click through to see how well it works for both sound suppression and underwater shooting.

Eye-Fi's X2 wireless SD cards, which provide your camera with a Wi-Fi connection have been around for a few years, and now the company has come out with a new range of 'mobi' cards.

Nikon President Makoto Kimura says the company could make a non-camera consumer product, prompting speculation that it's eyeing the smartphone market in response to falling compact camera sales. With compact camera sales down by around 25% across the industry, Kimura says he expects the company's DSLR sales to support the loss of compact sales for 'several more years' until it can produce 'a product that will change the concept of digital cameras.' Read more over at connect.dpreview.com
