Holograms were used mostly in telecommunications as an alternative to screens. A holocamera of any recorder or receiver would acquire the dimensions, form and movements of an object by means of ray scanning. This vision then could be transmitted simultaneously somewhere else, or stored and reproduced on a holoprojector at a later time. Projected holographic images were visible from all sides, although matterless. Holograms were initially monochrome with a cyan hue, though following the Clone Wars, an additional layer of color was added to some holograms. In full-duplex telecommunications, users could see each other’s holograms, as if they were in the same room talking to each other, although not always in relative proportion.

Standard holograms had a lesser quality than screens, since they were mainly monochrome and often flickered. The luxury versions could produce incredibly lifelike full-color images, and were mainly used for entertainment purposes, such as at the Holographic Zoo of Extinct Animals, or Hologram Fun World, though they could also be used for disguises and other deceptions.
