"A light meter is a device used to measure the amount of light."
How your camera measures the light in a scene to calculate the proper exposure.
Metering basics: Understanding the concept of metering in photography and how it works.
Types of metering modes: Different types of metering modes available in most DSLR cameras.
Evaluative metering: A metering mode that analyzes the entire scene to determine the best exposure settings.
Center-weighted metering: A metering mode that gives more emphasis to the center of the frame.
Spot metering: A metering mode that takes a reading from a small area of the scene.
Partial metering: A metering mode that takes a reading from a larger area than spot metering, but smaller than evaluative or center-weighted metering.
ISO and metering: How ISO affects metering and how to adjust it for the best exposure.
Aperture and metering: How aperture affects metering and how to adjust it for the best exposure.
Shutter speed and metering: How shutter speed affects metering and how to adjust it for the best exposure.
Exposure compensation: How to adjust the exposure settings in different metering modes for better exposure.
Metering in different lighting conditions: How to use different metering modes in different lighting conditions to get the best exposure.
Metering with flash: How to use flash in different metering modes for better exposure.
How to use the histogram to adjust exposure: How to read the histogram to adjust exposure settings for better exposure.
Advantages and disadvantages of different metering modes: A comparison of the different metering modes and their strengths and weaknesses.
Evaluative Metering: The camera evaluates the entire scene and adjusts the exposure settings accordingly.
Centre-Weighted Metering: The camera puts more emphasis on the centre of the frame when calculating the exposure.
Spot Metering: The camera measures the light intensity at a single point in the scene, typically the centre point, and adjusts the exposure accordingly.
Partial Metering: Similar to spot metering, but the camera measures the light intensity in a larger portion of the scene, typically about 10-15% of the frame.
Matrix Metering: A type of evaluative metering used in Nikon cameras that divides the scene into multiple zones and calculates the exposure based on the brightness of each zone.
Highlight-Weighted Metering: This mode attempts to preserve highlight detail by underexposing the image. It is generally used in scenes with bright highlights.
Centre-Spot Metering: Similar to spot metering but the camera considers a larger circle around the centre focus point.
Multi-Zone Metering: Measures light in multiple areas throughout the image frame to calculate exposure.
Average Metering: Measures light from the entire scene to calculate exposure.
Backlight Metering: Adjusts exposure for backlighting so that the subject is not underexposed.
"In photography, an exposure meter is a light meter coupled to either a digital or analog calculator which displays the correct shutter speed and f-number for optimum exposure."
"Similarly, exposure meters are also used in the fields of cinematography and scenic design, in order to determine the optimum light level for a scene."
"Light meters also are used in the general field of architectural lighting design to verify proper installation and performance of a building lighting system."
"Light meters also are used in assessing the light levels for growing plants."
"...coupled to either a digital or analog calculator which displays the correct shutter speed and f-number for optimum exposure."
"To ensure optimum exposure, given a certain lighting situation and film speed."
