Refers to the making of chronophotographs, recording motion or change with a still camera of a series of photographic images, either discrete photographs taken sequentially or a single exposure capturing movement, with a blurred effect on the images of the people and objects moved. Not to be confused with "cinematography," which is the photography of people and objects in motion with a motion picture camera.
