DPReview published interview with Ren Ng, Lytro CEO and founder. Explaining the future of light field photography trading higher resolution for wider focusing range, Ren says:
"As well as a scientific and commercial breakthrough, this could cause a technological breakthrough. We've got to the stage where we're seeing 14-16MP sensors for compacts and 20-24MP in larger sensors. It's not technological limitations that are defining that figure, it's a marketing-driven progression. When we went from VGA to 1MP to 4MP sensors, that was technology growth."
"Growth in that underlying industry capacity hasn't stopped, there's just no demand for it. With 14MP, for print or web use, those are enormous images, so there's no great pressure to move on from there. But if you applied the technology being developed for mobile phone cameras and applied it to an APS-C sensor, you could in theory make a sensor with hundreds of millions of pixels - an order of magnitude beyond what we're currently seeing. With such a sensor in a light field camera, we'd be able to measure hundreds of millions of rays of light. Light field technology can utilize and re-invigorate amazing growth in density of sensors."
Ren also claims low light and yield improvements with Lytro tech:
"Light field technology is inherently more capable in low light - we can shoot wide-open with apertures larger than make any sense for conventional photography. And we're not just trying to make enormous pictures. One dead or noisy pixel in conventional photography is expected to result in one output pixel in the final image. In light field photography it translates to a dead 'ray' which won't have as much impact on the final output - the sensitivity to defects from the sensor will go down."
