ISO

The ISO function allows you to set the
sensitivity of the camera's light sensor
based on the brightness of the scene. To
improve the camera's sensor performance in
darker environments, a higher ISO value is
required. A lower ISO value is needed when
shooting in brighter conditions.
Pictures taken at higher ISO settings will
generally have more noise than those taken
at lower ISO settings. (Adjustable in

corresponding to the manually set shutter
speed so as to obtain a most suitable

may be shown by adjusting the shutter
speed. High shutter speed can make you
clearly capture the movement of fast moving
object while low shutter speed can allow you
to take a picture for fact moving object with
a strong sense of movement. (Adjustable in
