International Cinematographers Guild
The International Cinematographers Guild (IATSE Local 600) represents approximately 8,400 members who work throughout the United States, Canada and the rest of the world in film and television as Directors of Photography, Camera Operators, Camera Assistants (1st AC, 2nd AC), Digital Imaging Technicians, Still Photographers, and all members of camera crews. == History == The first cinematographers union, International Alliance of Theatrical Stage Employees Local 644 was established in New York in 1926, followed by unions in Los Angeles and Chicago, but it wasn't until 1996 that Local 600 was born as a national guild.
