Manipulating 4D light fields for creative photography

We demonstrate how 4D light field images can be used to create artistic photographic effects. Traditionally, 4D light fields have been used in photography to perform digital image re-focusing, rendering of 3D models, and creating anaglyphs for 3D viewing. By having information about the paths of light within a camera, we can simulate different optical ab-berations to achieve results similar to those of novelty lenses, such as the ones from the LensBaby family. The images can be created realistically, with minimum human intervention in adjusting the parameters for desired types and degrees of effects.
