® ISO Speed (p. 84)
The ISO speed is the numeric representation of
the camera's sensitivity to light. The higher the
ISO speed, the higher the sensitivity. A high ISO
speed allows you to shoot images in dark indoor
or outdoor conditions without a flash and also
helps prevent blurred images due to camera
shake. This is convenient when shooting images
in places where flash photography is prohibited.
The ISO speed setting makes full use of the
available light, resulting in images that convey
the feel of the place they were shot.
