Shoot first, focus later with Lytro camera

I can’t count how many photos I’ve taken through the years that have been misfocused. But misfocused photos may soon be a thing of the past. A new technology promises to let you focus after a photo is taken!

The Lytro camera uses a new kind of sensor called a light field sensor. It substitutes software for many of the internal parts of standard digital camera.

The technology captures all the light rays in a scene and, remarkably, allows you to focus a photo after it was shot.

According to the Lytro website, their light field sensor captures the color, intensity and vector direction of the rays of light. This directional information is completely lost with traditional camera sensors, which simply add up all the light rays and record them as a single amount of light.

You can change the focus point anywhere in a photo by clicking on it. Not only can you selectively focus, you’ll be able to bring everything into focus in an entire photo. Photos taken with the camera need to be viewed on a computer screen.

Lytro cameras do well at capturing pictures in low light without use of a flash. It can capture data for three-dimensional images that can be viewed on a computer while wearing 3-D glasses. It also eliminates shutter lag that plagues so many compact digital cameras.

Pricing is expected to be competitive with current consumer cameras. If you’re intrigued by the possibilities of this camera, which is expected to be released within a year, sign up at the Lytro website to be notified by email when it becomes available.
