Asked on Oct 29, 2025

Answer

To measure exposure using a light meter on set, you need to understand how to read the light falling on your subject and adjust your camera settings accordingly. This process involves using an incident light meter to measure the light in the scene, ensuring accurate exposure for your shots.

Set your light meter to the correct ISO and frame rate settings that match your camera.
Position the light meter at the subject's location, pointing the dome towards the camera lens.
Take a reading to measure the incident light, and use this information to adjust your camera's aperture, shutter speed, or ISO for proper exposure.

Additional Comment:

Ensure the light meter is calibrated and set to the same ISO as your camera for accurate readings.
Consider the lighting contrast in the scene and adjust exposure settings to maintain detail in highlights and shadows.
Use the light meter to check different areas of the scene to ensure consistent exposure across the frame.
