The company behind the Lytro camera calls its technology "the first major change in photography since photography was invented," and reviewers seem to agree. By analyzing and storing all the points of light in any given photo, the Lytro allows users to refocus the subject, or focus on an entirely new subject in the frame—after you've taken the picture. An 8GB model, which holds 350 pictures, will run you $399; for 16GB or 750 pictures, you'll spend $499. A sample of the reviews:
- Light field photography, the new tech behind the Lytro, is "hard to explain, but it’s amazing," writes Joshua Topolsky in the Washington Post. "Being able to refocus an image after it’s been uploaded to your computer will irrevocably alter your perception of what a photo is," and when he first saw a demo, he was "awestruck." It's not perfect—its shape and size are particularly irksome, and there's no flash—but it's definitely a "game-changer."
