Camera maintenance: The 1st AC cleans sensors, checks for dust, and ensures all camera components function properly before each take.
Log keeping: They maintain detailed camera reports including lens used, exposure settings, and shot duration for every take filmed.
Team leadership: The 1st AC supervises the 2nd AC and utility crew, delegating tasks like slate operation and equipment transport.

How It Works

The 1st AC operates at the intersection of art and precision engineering, using specialized tools and techniques to maintain image clarity. Their work begins before filming and continues through post-production handoff.

Focus marks: The 1st AC places tape on the floor at precise distances from the camera to guide focus adjustments during actor movement.
Follow focus: They use calibrated gears attached to lenses, allowing smooth focus transitions across multiple feet of travel.
Slating: The 1st AC ensures the clapperboard is properly framed and synchronized, capturing scene, take, and camera data.
Camera rigging: They mount cameras on dollies, cranes, or gimbals, ensuring balance and safety under up to 50 lbs of gear.
Exposure checks: Using light meters, the 1st AC verifies that aperture settings match the DP’s requirements within 1/3 stop accuracy.
Digital workflow: They manage media offload, verify file integrity, and ensure 100% backup of all camera data.
