Researchers at the Massachusetts Institute of Technology have come up with a theory for a new way to solve the issue of bright skies burning out in a landscape photograph. Using what they call Unbounded High Dynamic Range photography they are working on the idea of pixels that reset themselves once they have reached their capacity for recording light so that they can carry on recording - and resetting if necessary.

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.

The latest versions gain improved tone mapping tools that attempt to retain local contrast while increasing the overall range of tones included in the final image, along with upgraded alignment and de-ghosting.

Sony has announced smartphone image sensors that use clear pixels to improve low light performance and allow 'HDR videos' with greater dynamic range. The chips, which will be branded 'Exmor RS' also use the company's latest 'stacked CMOS' design to maximize the light capturing area of each pixel. Adding a white (clear) pixel to the conventional red, green and blue (RGB) filters has been proposed before but Sony says its processing allows it to 'heighten sensitivity without compromising its high resolution.' The first chips to use the design will be small, smartphone-targeted 1/3"-type 13MP and 1/4"-type 8MP designs.

Are High Dynamic Range photos appropriate for illustrating news? That's the debate that's been started by the Washington Post's use of an HDR image on its front page in January.

John Omvik, Marketing VP with HDR software maker Unified Color understandably disagrees. He's written us a response arguing that what we see is closer to HDR than, say, a mono photo shot with Tri-X film.
