exposure meter

An exposure meter is a device used in photography to measure the amount of light in a scene. It helps determine the optimal camera settings—such as aperture, shutter speed, and ISO—to capture a well-exposed photograph. By assessing the light levels, the meter ensures the image isn’t too dark (underexposed) or too bright (overexposed). Modern cameras often have built-in exposure meters that provide real-time readings, while handheld meters are used for more precise control, especially in complex lighting conditions. This tool is essential for achieving balanced, accurately exposed images.
