lightmeter
Photographer's brightness tool
A lightmeter is a device that measures the intensity of light, used primarily in photography to determine correct exposure settings.
Photographers check the lightmeter reading to set aperture and shutter speed: The lightmeter indicated we needed a wider aperture.
Most modern cameras have built-in lightmeters, though handheld versions remain popular for studio work.
Also spelled as two words: light meter.
