An instrument for measuring the intensity of light so as to determine the shutter and aperture setting necessary to obtain correct exposure. Exposure meters may be built into the camera or be completely separate units. Separate meters can sometimes measure the light falling on the subject (incident reading) as well as the light reflected by it (reflected reading) ; built-in meters measure only reflected light. Both types of meters may be capable of measuring light from a particular part of the subject (spot metering) as well as taking an overall reading. Commonly called a light meter.
A device used to measure the brightness of the subject or illumination level at the subject position. This information and the film speed can be used to determine appropriate camera aperture and shutter speed settings.
Light Meter. Device used to measure the amount of light falling on, or reflected from, an object.
a device that counts the rate of light entering the spectrograph.
An instrument with a light-sensitive cell that measures the light reflected from or falling on a subject, used as an aid for selecting the exposure setting. The same as a light meter.
An instrument used for measuring the amount of light falling on or being reflected by a given subject.
photographic equipment that measures the intensity of light
a device that determines how much light the film should receive to make a correctly exposed print that is neither too dark nor too light
a tool for determining combinations of aperture and shutter speed that will provide optimum exposure for a particular scene
Instrument which measures the strength of the light, usually by means of a photoelectric cell, and indicates the exposure required. Often built into the camera.
Built-in digital camera meter that measures the amount of light when framing a photo and determines the best exposure. Matrix (Evaluative), Spot and Center-weighted are the main metering types; some digital cameras have all three.
Measures light intensity and converts this into an electronic signal. This signal is then used by the camera's electronic systems to determine a suitable exposure length.
A device which measures the amount of light (ambient or flash). Most cameras have a built-in light exposure meter that is used to determine the correct exposure. In underwater photography, separate (external) light meters are commonly used since built-in meters are not always easy to operate when wearing a mask.
An instrument for measuring the amount of light (available or flash) falling on or being reflected by a subject, and converting this measurement into usable information: shutter speed and f stop. (see Existing light , f-stop & Shutter speed )
An instrument that measures the amount of light and provides aperture and shutter speed combinations for correct exposures. Exposure meters may be built into the camera or they may be separate instruments.
An instrument containing a light-sensitive cell used to measure the amount of light reflected from or falling on a subject. The measurement is usually expressed in shutter speed and aperture combinations that will render an acceptable exposure. (Also known as a light meter.)
A device that measures available light and computes correct exposure.
an instrument that measures the amount of light falling on a subject ( incident light) or emitted or reflected by a subject ( reflected light), allowing aperture and shutter speed setting to be computed. Commonly called a light meter
