Multi-lens, multiple-focus, 100 megapixel camera may sound like the realm of sci-fi.  However, Adobe has already built a prototype to show off some of the capabilities of light-field photography.

This prototype works using 19 lenses to take images at multiple depths and angles simultaneously.  Adobe's software will dynamically enable the viewer to select a combination of independent focal points in various portions of the images.  A totally awesome concept.  - Wan Chi Lau
