Lytro adds more ways to interact with its living pictures

Photos taken with Lytro's light field camera (aka living pictures) were already more interactive than a regular snapshot, letting you endlessly refocus the images by clicking on different parts of them. An upcoming software update takes the interactivity up a notch, letting you change the perspective of your shots, too.

The free Lytro Desktop software update, which rolls out December 4, adds this Perspective Shift feature, enabling Lytro users to slightly change the point of view of a living picture by clicking and dragging it in any direction.

For example, click and hold on the picture at the top … Read more

Lytro unveils radical new camera design

Get ready for camera 3.0. Because next year, you might have to decide whether an 11-megaray sensor is enough for your new light-field camera.

Lytro, a Silicon Valley startup, today unveiled its radical new camera--also called the Lytro. With it, the company hopes to rewrite the rules with a technology called light-field photography, but the scale of the company's ambition is matched by the scale of its challenge.

On the outside, the Lytro looks different--a smooth, two-tone elongated box 4.4 inches long and 1.6 inches square. At one end is the lens and at the other … Read more

Start-up Lytro tries refocusing camera industry

A start-up called Lytro hopes to revolutionize photography by selling a camera later this year that lets people focus their images after the fact.

The technique used is called light-field photography, and it's been an active area of research for years in the optics realm. With it, lens and image sensor technology doesn't focus on a particular subject, but instead gathers light information from different directions; processing after the fact means different aspects of the scene can be recreated.

Lytro has been working on the technology for years--I interviewed Chief Executive Ren Ng three years ago when his … Read more

Pelican shows slim phone-camera prototype

In academic circles, light-field photography is nothing new. Now, though, a start-up called Pelican Imaging has unveiled a prototype of the technology geared to improve mobile-phone cameras.

Light-field photography--and the related concept of a plenoptic camera--is a complicated concept involving an array of small images rather than one large one. Essential to the process is computational image processing that can extract an actual photograph from the jumble of raw data.

And not just any image, but several images. Light-field photography captures enough data that a person can adjust focus after the shot has been taken and perform actions such … Read more

Photo industry braces for another revolution

Think of it as digital photography 2.0.

In the last decade, photography has been transformed by one revolution, the near-total replacement of analog film cameras by digital image sensors. Now researchers and companies are starting to stretch their wings by taking advantage of what a computer can do with sensor data either within the camera or on a full-fledged PC.

Some elements of this new era, which researchers often call computational photography, are refinements of existing technology. For example, some cameras can wait to take the photo only when subjects are smiling and not blinking, in effect placing the … Read more

Start-up lets you fix focus after snapping the shutter

It's one of the oldest, most common problems in photography: that picture you thought would be the prize shot is out of focus.

Refocus Imaging, a Silicon Valley start-up, thinks its technology can be used to make cameras that can fix that problem--after you take the photo.

By fitting a camera's image sensor with a special lens and then processing the resulting data with new methods, Refocus Imaging's technology will let photographers fix their photos and exercise new creative control after the shutter is released, founder and Chief Executive Ren Ng said.

"There's a lot … Read more
