A regular photograph captures the intensity pattern of light at a particular location at a particular time.
Holograms recreate the interference pattern of light in a volume of space. By interfering two coherent sources using a film that has the interference pattern captured, you recreate the interference pattern. Hence it exists in 3-D.
