Former Carmike Cinemas general manager and longtime projectionist Smith recently shared his insights on a remarkable piece of cinema history — an antique carbon arc projector that once brought movies to life long before the digital age.
With more than 23 years of experience as a projectionist and a career in EMS now behind him, Smith described seeing the machine as “a huge treat,” calling it both “old” and “ancient” in the best possible way. The projector stands as a reminder of how far film technology has come and how much craftsmanship once went into the moviegoing experience.
The projector operates using a carbon arc lighting system, a method that predates the xenon bulbs many theaters later adopted. Carbon rods — one positive and one negative — would create an intense arc of light that projected images onto the screen. As the carbon rods burned down over time, operators had to constantly adjust the spacing between them to maintain proper brightness. The adjustment mechanisms are still visible on the machine today, offering a glimpse into the hands-on work projectionists once performed during every showing.
Smith explained that eventually theaters transitioned away from carbon arc systems and into xenon bulb projectors, which became the industry standard for decades before digital projection completely transformed theaters in recent years.
The projector also represents a time when nitrate film was commonly used. Highly combustible and notoriously dangerous, nitrate film created significant fire risks when paired with the open flame-like intensity of carbon arc lighting. Smith compared the setup to “using gasoline and an open flame,” emphasizing just how hazardous early film projection could be.
While the exact retirement date of the projector is unknown, Smith estimated it likely stopped being used sometime in the 1970s or 1980s. Today, however, the machine still holds tremendous historical value — especially for cinephiles and collectors of vintage theater equipment.
Rather than being forgotten, Smith believes the projector deserves to remain on display. He suggested it would make a perfect centerpiece in a theater lobby, allowing visitors to appreciate the history behind early movie presentations. For older generations who may have watched films projected on similar machines in the 1930s and 1940s, the sight of it could bring back powerful memories of cinema’s golden age.
