Understanding Contrast
The graph peaks gradually for images in which contrast is balanced. The
graph peaks on both sides but sinks in the middle for images with a large
difference in contrast and low amounts of mid-level brightness.
This camera is equipped with an electronic level for detecting whether
the camera is level. When [Electronic Level] is set to
O
(On), the
electronic level can be displayed by pressing the 4 /
W
button.
A bar graph indicating the horizontal camera angle appears at the
bottom of the screen, and a bar graph indicating the vertical camera
angle appears on the right side.
