Multi-segment metering (originally devised by Nikon for its FA SLR of 1983 under the name AMP: Automatic Multi-Pattern metering). Matrix was introduced to the world in 1988 with the Nikon F4. Now available from most manufactures under varying names. Light coming from the subject passes through the lens into the viewfinder where it strikes a 10 segment light meter (in the current Nikon F6), this gives the camera a better chance of obtaining the correct exposure for the main component of a particular image.
Some of the more advanced SLR cameras rely on a metering system known as Matrix Metering. The camera divides the view finder into a grid and meters separately for each square created by the grid. The readings for each square is then compared against a set of preset values to determine the proper aperture and shutter speed settings.
is an reflected light metering system built into many digital camera. It interprets a series of readings from different points around the frame to arrive at a suggested exposure.
An exposure system included with some cameras that breaks the scene up into a grid, then evaluates each section of the grid to produce the best possible exposure.
Advanced camera exposure metering system. Nikons with this metering mode use a multi segment sensor a computer and an extensive scene data bank. A great method to insure a high success probability to correct exposure under most lighting situations. Contrary to popular belief, this includes backlit subjects and tricky scenes with the sun in them.
