certain aspects of systems and techniques for efficiently recording captured plenoptic image data and rendering images from captured plenoptic data. Plenoptic image data can be captured by a plenoptic or other light field camera. In some implementations, four-dimensional radiance data can be transformed into three-dimensional data by performing a radon transform to define the image by planes rather than radii. A resulting radon image can represent the summed values of energy along each plane. the original three-dimensional light density of the scene may be recovered, for example, by performing an inverse radon transform. images from different points of view and / or having different focus can be rendered from the light density.
