Holograms, often nicknamed "holos", are a form of photography utilized by terrans that allow an image to be recorded in three dimensions. They are present in many forms of communication, ranging from military matters to televised media. Unlike flatscreen imagery, holograms are notoriously hard to fake and as such were the favored form of communication for the Sons of Korhal in the broadcasting of propaganda, making it difficult for authorities to edit them. Some holograms are molecular in nature, allowing terrans to manipulate them with their hands.
Holographic images also exist in forms akin to posters and photographs.
In the public sector, the quality of hologram equipment varies. A basic set will display a single image while more advanced equipment can show a background. The image can be frozen and the size of the image can also vary, ranging from a life-size image of an individual to being scaled down to fit on the side of a desk or in the palm of one's hand. Holographic images can be recorded by holocams.
