Digital methods of image capture and display processing have enabled the new technology of "light field photography" (also known as synthetic aperture photography). This process allows focusing at various depths of field to be selected ''after'' the photograph has been captured.<ref>[[Ren Ng|Ng, Ren]] (July 2006) [https://web.archive.org/web/20120916121457/http://www.lytro.com/renng-thesis.pdf Digital Light Field Photography]. PhD Thesis, Stanford University</ref> As explained by [[Michael Faraday]] in 1846, the "[[light field]]" is understood as 5-dimensional, with each point in 3-D space having attributes of two more angles that define the direction of each ray passing through that point.

These additional vector attributes can be captured optically through the use of [[microlenses]] at each pixel point within the 2-dimensional image sensor. Every pixel of the final image is actually a selection from each sub-array located under each microlens, as identified by a post-image capture focus algorithm.
