Motion Pictures Production Science Project Idea

How motion pictures are produced.The moving picture machine which has come to play such an important part in our lives in giving us recreation and instruction is really a projection lantern in which the pictures to be projected are very small, and developed on a roll of transparent celluloid or a similar substance.

The pictures were taken by a camera in which the photographic film was drawn along by a revolving mechanism, thus getting a succession of exposures of moving objects, each exposure differing slightly from the succeeding one, as the movement progresses.By a mechanism similar to that used in taking them, the successive pictures are thrown upon the screen.However, we do not see them as separate pictures, but as one, in which the motions of the original subject are reproduced.

The way in which a succession of pictures appears as one continuous picture is well illustrated by the appearance of the spokes of the wheels of a rapidly moving automobile.Do you see each individual spoke?A lantern swung rapidly in a circle is seen as a circle of light.It is evident that the image of an object does not disappear immediately upon the disappearance of the object.
