Methods and apparatus for light-field capture with large depth of field. A design methodology is described in which the relationships among various plenoptic camera parameters, including inverse magnification, F-number, focal length, wavelength, and pixel size, may be analyzed to design plenoptic cameras that provide increased depth-of-field when compared to conventional plenoptic cameras. Plenoptic cameras are described, which may be implemented according to the design methodology, and in which both Keplerian telescopic and Galilean telescopic imaging can be realized at the same time while providing a larger depth of field than is realized in conventional plenoptic cameras, thus capturing light-field images that capture “both sides” in which all but a small region of the scene is in focus. In some embodiments, apertures may be added to the microlenses so that depth of field is increased.
