Holography - Wikipedia, the free encyclopedia
A lens is required in photography to record the image, whereas in holography, the light from the object is scattered directly onto the recording
Early lens designs resembled a giant glass beehive, with a light at the center (see examples below). The lens could be as tall as twelve feet high
