Sensitivity and Motion Blur Sensitivity and Motion Blur
If you choose a narrow aperture when the subject is poorly lit, the shutter
speed selected by the autoexposure program may not be fast enough to pre-
vent motion blur (see the top illustration at right). For faster shutter speeds
that reduce motion blur as shown in the second of the two illustrations at right,
select a higher sensitivity.
