the end result: the ability to refocus pictures, even after you've taken them.

To achieve such magical endeavors the Lytro camera uses heaps of custom software (armed with a custom .lfp file format) coupled with some serious silicon to measure not just color or the intensity of light, but its direction, too. The latter is achieved with an eleven "megaray" sensor, which is bolted to an f/2.0 8x optical zoom lens, all encased within that sleek body. Seeking to save us from unfocused mishaps, the technological tour de force also unlocks some considerable creative potential. So, is the $399 shooter going to revolutionize photography as we know it? Or does the Lytro's first foray into consumer electronics fall prey to the shortcomings of 1.0 product?
