Histogram
A histogram is a graph indicating the image’s
brightness. The horizontal axis indicates the
brightness level (darker on the left and brighter
on the right), while the vertical axis indicates how
many pixels exist for each brightness level.
The more pixels there are toward the left, the
darker the image. And the more pixels there are
toward the right, the brighter the image.
If there are too many pixels on the left, the
shadow portions will lose detail. And if there are
too many pixels on the right, the highlights will be
washed out. The tones in-between will be
reproduced.
By checking the image and its histogram, you can
see the exposure level pattern and the overall
tone reproduction condition.
Highlight Alert
When the image information is displayed, any overexposed areas of
the image will blink. To obtain more image detail in the overexposed
areas, set the exposure compensation to a negative amount and shoot
again.
