What does an assistant camera do?

An Assistant Camera, often referred to as a 1st or 2nd AC, is responsible for supporting the camera department on a film or television set. Their primary duties include maintaining and setting up camera equipment, pulling focus, marking actors' positions, and ensuring the camera runs smoothly during shoots. They work closely with the Director of Photography and Camera Operator to achieve the desired visual style. Additionally, Assistant Cameras manage lenses, batteries, and memory cards, and help troubleshoot technical issues on set.
