Motion blur is a feature of traditional cinematography. It is the blurring of the image of a moving object in photographs, film, or video, which occurs when the motion is rapid in relation to film speed, or (in the case of stills) at low shutter speeds.¹
The 24 frame per second cadence of traditional camera systems don’t provide enough temporal resolution to adjust the amount of motion blur in post-production. The Lytro Cinema camera captures at 300fps which allows the creation of motion blur in post-production so it can become a more flexible creative decision.
