Learning Lytro – Light Field Camera Review

LytroI had never heard of a “light field” camera until I began hearing marketing buzz about the Lytro camera last year. To be perfectly honest, I still don’t really understand how the technology works. I have a pretty good layman’s grasp of how normal lens optics work to focus an image onto film or a CCD sensor, and how and why focusing at a certain depth works, but the “light field” camera concept still seems a bit like magic. They say that it captures not only the intensity and color of the light hitting each sensor pixel, but the direction of said photon as well. Huh? And somehow this magically allows the focal length (what depth in the image is in focus) to be modified after the moment has been captured, just like they do in Hollywood movies and television where a detective tells a lab geek to “enhance this area of the photograph here” and they can now magically read the perp’s license plate. Like I said, it still seems a bit like magic, but it really, really works.
