  8. Communication with the DP: ACs maintain clear communication with the DP to understand their vision for each shot. They receive instructions on focus points, framing, and any specific requirements for the camera operation.

  9. Clapperboard Operation: ACs often assist with the use of a clapperboard or slate at the beginning of each take. This helps synchronize sound and picture, provides information for post-production, and aids in organizing footage.
