What is the difference between incident and reflective light metering?
Incident light metering measures the light falling on the subject, typically using a handheld meter with a white dome. Reflective light metering measures the light reflected off the subject, often built into cameras.
How does light metering affect exposure in photography?
Light metering evaluates the intensity of light in a scene to determine the optimal exposure settings. It guides the camera in adjusting aperture, shutter speed, and ISO, ensuring the captured image is neither too dark nor too bright, thus achieving balanced exposure.
What are the common types of light meters used in photography?
The common types of light meters used in photography are reflected light meters, which measure the light bouncing off a subject, and incident light meters, which measure the light falling onto a subject. Additionally, spot meters measure light in a narrow area, while flash meters specifically measure light from a flash.
How can I calibrate a light meter for accurate readings?
To calibrate a light meter, first ensure it is set to the correct ISO for your camera. Use a neutral 18% gray card in consistent lighting to compare and adjust meter readings against the camera's exposure settings. Adjust the exposure index (EI) if necessary. Regularly test and recalibrate when using different lighting environments.
Why is light metering important in videography?
Light metering is crucial in videography because it ensures the proper exposure, balancing light and shadow to achieve the desired aesthetic. It helps maintain image quality, prevents overexposure or underexposure, and enhances the visibility of details, ultimately supporting the storytelling and artistic goals of the video.
