      Hi meg!

      3D cinema screenings screen two pictures over each other, one for the right eye and one for the left eye. The glasses let you see the right one with each eye by using polarising glasses that each just let you see one image withe each lens. It actually creates an optical illusion of depth in the images!

    A bright lights are held behind the movie film image and shone through it (this is all in the projection box behind the audience), and the shaddows are visible on the big screen in front of the audience. The movie film images are swapped about 20 times each second for the next one, so the shaddows look to us like they’re moving!
