Light MeteringSlide13
Matrix Metering
In this mode the camera attempts to take into consideration everything in
your frame.
Most
cameras will have numerous metering zones around the frame. Slide14
Matrix Metering
Matrix Metering or Evaluative Metering mode is the default metering mode on most DSLRs. It works by dividing the entire frame into multiple “zones”, which are then all analysed on individual basis for light and dark tones. One of the key factors (in addition to colour, distance, subjects, highlights,
etc
) that affects matrix metering, is where the camera focus point is set to. Slide15
Spot Metering
This mode tells the camera to do it’s metering from a very small ‘spot’ in the scene.Slide16
Spot Metering
Spot Metering only evaluates the light around your focus point and ignores everything else. It evaluates a single zone/cell and calculates exposure based on that single area, nothing else. Slide17
Center Weighted Metering
On the spectrum between overall metering and spot metering we find the Centre
Weighted Metering mode which takes a little from both ends of the spectrum and tells the camera to focus it’s metering decisions upon the
centre
of your image (although a wider area than spot metering). Slide18
Center Weighted Metering
Using the whole frame for determining the correct exposure is not always desirable. What if you are trying to take a headshot of a person with the sun behind? This is where centre-weighted metering comes in handy. Centre-weighted Metering evaluates the light in the middle of the frame and its surroundings and ignores the corners. Compared to Matrix Metering, Centre-weighted
Metering does not look at the focus point you select and only evaluates the middle area of the image.Slide19

-Weighted
When
General subjects without larger shadowed or extreme bright areas. Action photography.
Big differences in brightness
or for subjects that require precise measurement, such as close-up photography.
Main subject covers a large portion of your image.
Pros
Comfortable with good reliability.
Precise metering in your control.
Metering mode for
general scenes
Cons
No control of the exposure settings
Heavy variations in metering results.
Risk of over-exposing for scenes with major picture areas covered by sky. Slide20
