2. Check the histogram
Just
like the Levels display in image editing software packages such as Adobe
Photoshop, a camera’s histogram display is a graph that represents the
brightness of the pixels that make up an image.
The
scale runs from black, with a brightness reading of 0, on the left to white,
with a brightness reading of 255, on the right.
The
peaks in the histogram indicate the number of pixels with that brightness and a
large peak means lots of pixels have that brightness.
This
means that a very dark image will have peaks over to the left of the graph,
while a bright one has peaks on the right.
Meanwhile,
a correctly exposed ‘ideal’ scene has a histogram with a so-called ‘normal’
distribution with a peak in the middle and just a few very bright and very dark
pixels.
Checking
the histogram after every shot will increase your understanding of the
brightness distribution of an image.
It
will also enable you to determine whether an image is under- or over-exposed
with the majority of pixels being grouped to the left or right of the graph respectively.
