Lytro Camera Refocuses on Upscale Audience




This is Scientific American's 60-Second Tech. I'm Larry Greenemeier. Got a minute?
Until a few years ago even the best digital camera couldn't fix an out-of-focus photo.
A start-up called Lytro introduced a solution to this in 2012 when they created a camera that lets you snap pictures and play with the focus afterward.
That neat gadget cost $400 and looked like a mini telescope.
A new version expected this summer will offer additional advances.
Called the Lytro Illum, it looks like a serious SLR camera and has a $1,600 price tag.
The Illum still uses a special sensor covered by a matrix of microlenses, which capture the entire light field.
That's an enormous amount of data about the color, brightness and direction of all light rays within a frame.
The camera doesn't have a focus mechanism,
it comes up with an image based on a massive data analysis.
You can then go in and change its choices.
The Illum improves on the original Lytro with a much faster sensor and processor,
the same one Samsung uses in its new Galaxy S5 smartphone.
Probably more camera than most of us need.
But a lifesaver when you screw up a once-in-a-lifetime photo.
Thanks for the minute, for Scientific American's 60-Second Tech. I'm Larry Greenemeier.
