The International Stereoscopic Union is an organization made up of 3D photography enthusiasts all over the world. They have country representatives in over thirty countries. They meet on odd numbered years in their conventions called "congresses" which are held in locations around the world .

The National Stereoscopic Association is a large organization with its roots in the collecting of stereocards that are in the general shape of their logo to the left. They have since branched out to include modern 3D photographic topics as well. They publish "Stereo World" six times a year in a larger format that the ISU's "Stereoscopy" and with a superb quality as well. They have a yearly convention that changes location within the USA each year. The 2004 convention was hosted by the CSC. Occasionally, the NSA convention and ISU congress will be held jointly.

The Photographic Society of America is a very large, prestigious, and long standing photography organization that includes nearly all aspects of photography, including stereo 3D photography. They are the organization that sanctions most of the CSC exhibitions. They maintain a point system though which photographer achievement can be recognized through attainment of higher and higher point goal thresholds. One way points are earned is by photographers getting their images accepted into the CSC's PSA-related exhibitions as well as for being an expert judge in those events. Their website's stereo division is here: [link]
