The Adobe Light-Field Prototype Lens is a lens cluster. Unlike the Standford micro-lens array in their light field camera system, the Adobe lens cluster comprises a honeycomb of 19 units of 5.2 megapixel lens. Like the Stanford cousin, each of these lens is positioned at different angles so that each lens captures individual images during a single exposure of the same scene. Clever programming then combines these 19 layers of images into one single master image. This enables users to change 19 depths of field, or commonly called focussing points, after post processing.
If you are a pixel peeper, let’s do some math. Multiply 19 and 5.2 Megapixel. The answer will tell you Adobe’s prototype light field lens cluster is capable of generating a massive 100 megapixel image per exposure. If any photographer is already struggling with storing images from 12, 15, 18, 22, 24 Megapixel cameras, how much more harddisk real estate would you require should Adobe churns out a commercial model of this prototype camera? Notwithstanding the image and file size, this development is indeed exciting for the imaging community.
