Although I'm a scientist by training, having recently completed my Ph.D in biophysics, photography has always been a huge passion of mine. When I saw an opportunity to meld the two at DPReview, I jumped at it... and now here I am!

Which high-end full-frame camera should I buy? This roundup contains the majority of current full-frame camera offerings available. Full-frame cameras have image sensors as large as a frame of 35mm film, and for good reason: larger sensors offer the potential for better image quality, low light performance, and dynamic range. If you want a drastic upgrade to the image quality of your phone, or portraits with superior subject to background separation, it’s hard to beat what full-frame offers.
Pelican Imaging has released a set of re-focusable pictures taken with its light field camera for smartphones. Instead of placing an array of microlenses between the sensor and the main lens, Pelican uses an array of main lenses - each with a sensor behind it. Pelican's offering is more suitable for smartphones, and their sample images allow for re-focusing, changing DOF, and shifting perspective. Click through for more details and links to the images.
UPDATE: Sony has released an image taken with its curved sensor, and provided more details on what we might expect from its curved sensor technology. We've updated our previous story with this image and details. Read more
The A7S is Sony's newest entry in its full-frame mirrorless lineup. But where the 'R' in A7R stood for resolution, the 'S' in the 12MP A7S stands for sensitivity. We've recently received a Sony A7S and wasted no time putting it up against the A7R and Canon EOS 5D Mark III to see how it compares.
The sensors inside digital cameras are - generally - flat. But curved sensors promise greater sensitivity, better image quality, and provide scope for simpler lenses. Recently, Sony showed off some examples of curved image sensors, including (tantalizingly) a full-frame chip. Device manager Kazuichiro Itonaga claims: "The team has made somewhere in the vicinity of 100 full-size sensors with their bending machine. We are ready." Read on to learn more about this exciting new tech, how it imitates the human eye, and how it may find its way into consumer products.
As Lytro prepares for the launch of its second generation light field camera, the Lytro Illum, the company faces a challenge: how does one easily display and share the 'living pictures' their cameras produce? Today the company announced plans to open-source its Living Picture Player - a viewer for its light field images. The WebGL-based player can be integrated into any website or social media platform, thereby allowing for easy sharing of Lytro's living pictures. 500px will be the first to host an image gallery based on this player.
Earlier this week, Japanese patent blog Egami reported that Olympus has patented a technology that would allow the photographer to selectively adjust exposure of different scene areas during an exposure. This might allow for a more balanced exposure of scenes where cameras might normally struggle. Click through for an explanation of what we think the patent might mean for photographers.
