Holograms, often nicknamed "holos" or "holovids," 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.
In the military sector, holograms are capable of creating 'light banners' and tactical displays such as starmaps. By the time of the Defenders of Man Insurgency, holograms were being deployed on the field, allowing soldiers to create holo decoys that could help provide fire support.
In the Terran Dominion, holovids are a common form of art and entertainment and a booming industry. Directors such as Ottmar Drenthe are well known and recognized through most core Dominion worlds, and are considered to be cultural and artistic staples. Holovids are also enjoyed through many of more fringe, backwoods worlds, but usually show holos that are considered to be of lesser quality. Holovids are also used for marketing, and companies such as the Axiom Corporation will often seek out famed holovid directors for propaganda pieces.
In parallel to the holovid industry, there also exists holo reviewers, who give ratings on the current releases.
