Using the Histogram

3
A histogram shows the brightness
distribution of an image. The horizontal
axis represents brightness (dark at the left
and bright at the right) and the vertical axis
represents the number of pixels.
The q features two histogram
displays. The "Brightness histogram"
shows the distribution of brightness and
the "RGB histogram" shows the
distribution of color intensity.
1 Histogram Display (p.25)
The shape of the histogram before and after shooting tells you whether the
brightness and contrast are correct or not, and lets you decide if you need to use
EV compensation and take the picture again.
1 Setting the Exposure (p.161)
Understanding Brightness
If the brightness is correct, the graph peaks in the middle. If the image is too dark,
the peak is on the left side, and if it is too bright, the peak is on the right side.
Dark image
When the image is too dark, the part to the left is cut off (dark portions with
no detail) and when the image is too bright, the part to the right is cut off
(bright portions with no detail).
Bright portions blink red on the LCD monitor and dark portions blink yellow
when Bright/Dark area is on.
