Understanding and Choosing Camera Metering Modes
In this video we’ll be learning about the different metering modes available on your camera and how to choose the best metering mode for the situation you are shooting in.
Digital SLR exposure meters are so accurate because they interpret the actual light passing through the lens, which the mirror flips upward toward the viewfinder.
The camera uses a portion of the light for viewing the image and some for measuring the exposure. If you zoom the lens or place a filter in front of the lens to modify the light, the meter sees the results and takes them into account. Metering system is also linked to the shutter speed and aperture controls. So the metering system understands the effects of both shutter speed and aperture on the recommended exposure.
In the old days, most cameras came with a simple centre-weighted light meter. This meter measures the light throughout the image but applies more weight, to the central part of the scene in the viewfinder.
Is about 80% for the centre and 20% for the rest of the image .
Centre weighting is good for shooting portraits of close-up of flowers.
This mode is the default meter mode for most Digital Cameras.
It collects exposure data from many points on the screen and uses sophisticated algorithms to decide which points to use in calculating the correct exposure.
Any scenes that don’t require the special treatment provided by other methods. You can use matrix mode all the time.
This method makes its exposure recommendations based only on a centre spot shown in the viewfinder.
Illumination outside the spot is ignored,Your DSLR might allow you to choose the size of the centre spot.
