To ensure correct exposure, most analogue and digital cameras feature automatic light metering. Internal or external cells measure light intensity and convert the information into an electrical signal. This is then used by the camera to set the right shutter speed and aperture for the relevant light conditions. Modern exposure metering systems can measure the brightness of just a section of the scene, all areas or give more weight to certain areas. (Digital ESP/selective multi-zone metering), centre weighted average metering , spot metering, reflected-light metering, light metering)
Virtually all cameras on the market today have a built in light meter. This meter is used to gauge the amount of light present to determine the proper aperture and shutter speed for a given frame. Hand held meters are also available to use in addition to the camera's meter. The hand held meters offer more features and greater accuracy. Meters that gather light reflected by the subject like the on camera meters or Spot Meter are known as reflected meters. Incident meters are placed at the location of the subject and measure the amount of light falling on the object.
photographic equipment that measures the intensity of light
an instrument used to measure the intensity of light
a single-channel readout device for use with any of LI-COR's terrestrial light sensors
Instrument for measuring light levels and indicating the exposure required.
an instrument that measures the intensity of light in a particular area.
Or exposure meter, a device built in to the camera, or used separately in the lighting studio to determine exposure by measuring the action of light on a photoelectric cell. The meter can be used to measure incident or reflected light.
An electrical exposure meter for measuring light intensity.
a device used to calculate and measure the effective light in a tested area
A device for measuring the intensity of visible radiation to determine the appropriate exposure for acquiring photographs.
Tool that measures light in foot-candles then converts that reading to F-stops based on what speed of film you are using.
An instrument 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 an "Exposure meter.")
A light-sensitive measuring device used to evaluate the amount of light focused on a subject in order to set the proper exposure.
Is an alternate term for exposure meter.
A light sensitive device used for evaluating the amount of light in a scene for exposure. There are four types: Incidental meter, reflective meter, flash meter and spot meter
The built-in device that your point-and-shoot camera uses to measure light and determine the correct exposure settings.
A device that measures the intensity of light. Can be either built into a camera or a separate hand-held instrument. LiOn. Lithium ion battery.
Most cameras have a built-in light meter to measure the brightness of the scenes you photograph. The light meter reacts to light by sending instructions to the camera to set the right combination of aperture and shutter speed. Light meters can't sense colour only brightness.
The built-in device that the point-and-shoot uses to measure light and determine the correct exposure setting.
A light meter is a device used to measure the amount of light. In photography, a light meter is used to determine proper exposure. Given a film speed, the meter will show the camera settings (f-number and shutter speed) that nominally result in the “best” picture.
