The stroboscopic effect is the optical effect in filming of rotating wheels or objects having spokes or visible marks resulting in that the wheels or objects appea r to stand still or rotate backwards to the true and expected rotation. The strob o- scopic effect is a function of the ratio of intermittent frames per second o f the camera, the speed of rotation of an object or wheel and the number of visibl e markings or spokes on the rotating object or wheel. Before this innovation there is no system that makes it possible to eliminate, or control the stroboscopi c effect in film and video. The heretofore used methods are based on restrictive framing, restrictive angles and editing that try to exclude rotating objects or wheel s from the view of the audience. These restrictive methods seriously minimize the dramatic, artistic and expressive power of the filmed action.
