Understanding and switching between metering modes

- In order to get a good exposure,…you need to ensure that your camera has an accurate meter.…Most of the time, your camera will get it right,…but you can switch metering modes to help it out.…The most common method is Multi,…which produces natural results in most situations.…It evaluates the entire frame and then cuts it…into segments before establishing an exposure.…The camera looks at the overall tonal distribution…of the scene as well as the entire composition.…If you're using newer lenses,…it can also use distance as a factor.…

The Center option uses the entire frame,…but gives greater emphasis to the middle of the frame.…This is particularly useful when shooting portraits,…particularly if there's a strong backlight.…The Spot option looks at a very small area,…about a four-millimeter circle,…but we can actually adjust this,…and that's a small amount of the frame.…This is really only most useful if you want…to be very specific about what's used to set the exposure.…And your camera may have a few additional methods as well.…
