This is a short introduction to the 3d-Con. The National Stereoscopic Association is a non-profit organization founded in 1974, whose goals are to promote the study, collection and use of stereo photography. It has over 1,000 members. 3D-Con is traditionally the name of the NSA's annual convention, held somewhere different every year in the summertime.
What happens at a convention? The convention has programming for the collector as well as the photographer. Among the highlights are the trade show, the stereo theater, workshops, tours, and Special Interest Meetings meetings. In addition, we hold slide and print contests and showings of stereo (3D) photography. Website is https://3d-con.com/
