OTHER RECORDING FUNCTIONS
• When the histogram is too far
to the left, it means that there
are too many dark pixels.
This type of histogram results
when the overall image is
dark. A histogram that is too
far to the left may result in
“black out” of the dark areas
of an image.
• When the histogram is too far
to the right, it means that
there are too many light
pixels.
This type of histogram results
when the overall image is
light. A histogram that is too
far to the right may result in
“white out” of the light areas of
an image.
• A centered histogram
indicates that there is good
distribution of light pixels and
dark pixels. This type of
histogram results when the
overall image is at optimal
lightness.
IMPORTANT!
• Note that the above histograms are shown for
illustrative purposes only. You may not be able to
achieve exactly the same shapes for particular
subjects.
• A centered histogram does not necessarily
guarantee optimum exposure. The recorded image
may be over-exposed or under-exposed, even
though its histogram is centered.
• You may not be able to achieve an optimum
histogram configuration due to the limitations of EV
shift.
• Use of the flash as well as certain shooting
conditions can cause the histogram to indicate
exposure that is different from the actual exposure of
the image when it was recorded.
• This histogram does not appear when you are using
Coupling Shot (page 77).
