Idea: Multifocus Photography
- hiroprot 17y agoInteresting. This reminded me of a thought that I had when I was watching Avatar in 3D: the 3D effect was always focused on a specific part of the scene, and if you focused your eyes on a different part, it looked blurry. After I thought about it, it made sense: they can only create the 3D effect for a specific focus, otherwise they'd have to provide an individualized effect for every viewer. I wonder if/when we'll see a solution for this.

- stan_rogers 17y agoThe idea represents a fundamental misunderstanding of optics. Multiple pictures would only be required under low-light conditions when a suitable tripod is unavailable or to capture a subject in motion (both cases require a higher shutter speed, and therefore a larger aperture). In either case, a single camera could not capture the same subject in the same position and with the same framing, either due to subject or camera movement. The continuous-focus problem was solved a long time ago, first by the pinhole camera, then (when faster films began to appear) by photographers such as the members of Group f64. If you want to learn a bit more about the subject, there is a great book called "The Ins and Outs of Focus" that is now available as a free download: http://www.trenholm.org/hmmerk/download.html http://www.trenholm.org/hmmerk/download.html
