A light meter (short form meter) is a device that measures light to determine the proper exposure settings for a scene. Analog measuring instruments with photoelectric selenium photo cell as voltage source were the most common models of light meters for the average photographer. Nowadays digital instruments with other types of light sensors dominate the market, but selenium meters are still popular since they need no battery.
