Analog and digital photography share one main limitation: They only record intensities and colors of light rays that a simple lens system projects linearly onto the image plane at a single point in time and under a fixed scene illumination. This is still mainly the principle of the camera obscura that has been known since antiquity. Thus, most of the light rays that are propagated through space and time are not recorded.
...computational photography will enable features such as 3D recording, digital refocusing, synthetic re-illumination, improved motion compensation and noise reduction, and much more."
