What is the default ASA setting of a professional digital motion picture camera?

• A. 200 ASA
• B. 400 ASA
• C. 800 ASA
• D. 1600 ASA

Answer: (C)

ASA (or ISO) shows how sensitive the camera sensor is to light. The default base sensitivity is chosen to work well across a wide range of lighting on a professional set, giving a practical starting point for exposure. For cinema cameras, 800 ASA is a common native or base setting because it offers a good balance: enough light to keep scenes reasonably bright with clean highlights, while preserving usable shadow detail and keeping noise under control. If you drop to a lower setting, you’d need more light or longer exposure to avoid underexposure, which limits flexibility on set. If you raise it, you can shoot in dimmer conditions, but noise increases and dynamic range can drop, making the image look grainier. So 800 ASA is the typical default because it straps the camera to a versatile middle ground that works in many environments.
