light meters

A light meter is a device used by photographers to measure the amount of light in a scene. It helps determine the optimal camera settings—such as shutter speed, aperture, and ISO—to capture well-exposed images. The light meter evaluates the light intensity and provides either a numerical reading or recommends settings for proper exposure. This ensures that photos are neither too dark nor too bright, allowing for accurate representation of the scene's lighting conditions. Light meters can be handheld or built into cameras, making them essential tools for achieving consistent, high-quality photographs.
