Photography is all about light. If you expose your sensor to
too much light, you’ll bleach out the image; whereas not letting enough light
on to the sensor will result in the photo being too dark-and in both cases,
critical detail and colour be lost.
Multi Segment Matering
"Multi Segment" |
Multi Segment or Multi Zone matering as it’s otherwise
known, is the most recent addition to range of matering options available and
is the default setting on most cameras. Each manufacturer has their own
specific name for it. Canon call theirs Evaluative for instance, while Nikon
terms theirs as Matrix matering, but in essence, they all operate in a similar
way.
The entire image is metered, but is divided up to sections
to produce a much more accurate reading for the scence as each segment takes
its own reading. It’s so clever, that it knows which areas to give prominence
to and which areas of the image to ignore-bright skies,for instance, that could
fool a meter normally. Information from all segments is then combined and
cross-checked woith database in order to determine the best exposure possible.
