13. 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.

14. 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.

15. Spot Metering
This mode tells the camera to do it’s metering from a very small ‘spot’ in the scene.

16. 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.

17. 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).

18. 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.

19. Differen Light Metering Modalities
Matrix
Spot
Center-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. 

20. Focus Metering
We have said that the subject must be in focus, but how ?
