AUTO KNEE function
When shooting a foreground subject, such as a human
being, etc., with a high-brightness background, if the
brightness level is set for the foreground subject, the
background image will be blurred with white. In such a
case, a clearer background is obtained when the auto
knee function is used.
It is effective especially in the following cases:
• When shooting a human being indoors with a view
to the landscape out through a window.
• When shooting a human being in the shade on a
fine day.
• When shooting a high-contrast scene.
CAUTION:
If a fast moving high-brightness section like a car
in sunlight is shot, the auto knee function may
change the brightness of the entire image along
with the motion of the object. In this case, set the
auto knee function to OFF.
