What is a ‘Flick’ when it comes to movies?
In: Technology
* For decades movies were shown on film projectors.
* These devices rapidly show a series of still images imprinted onto a film strip that is run through the projector.
* For each frame of this film strip, the projector grabs the frame and holds it still for just a moment.
* Then a shutter blocks the light while the frame is released and the next frame is moved into place.
* Then the shutter is removed and the new frame creates a projection on the screen.
* This constant blocking and unblocking of the light from the projector creates a flickering light, especially in the back of the theater where the projector is.
