When does camera shake tend to happen,
and what causes it to occur?
Perhaps you've encountered blurred images when enlarging pictures: photos thai look fine in
smaller postcard sizes appear quite fuzzy at greoler size. In fact, camero shake happens more
frequently thon you'd think. There are several reasons for occidental blurring. One cause is the use
of a telephoto lens, which leis you shoot small subjects at higher magniFication, and also turns small
vibrations during shooting into heavy blurring of images. Another cause is shooling in dark places.
When taking pictures at lower shutter speeds, in on unsteady posture, or on an unstable platform
such as a train or a boot, blurring is quite common.
How can you best protect your pictures
from camera shake and blurring?
The most certain way

prevent camero shake is the use of a tripod. Additionally, use of flash can
effectively minimize blurring when shooting in low lighting conditions. However, it's inconvenient to
carry around a heavy, bulky tripod, and in some places, tripod use isn't even allowed. What's
more, the use of a flash may sometimes spoil the mood of a shooting scene
by
disrupting the
natural lighting nuances of the atmosphere. In any of these situations, Canon IS lenses are the
definitive solution to blurring problems. Just a single IS lens can help you capture imoges in a
natural light, without other equipment or special set-up, wherever and whenever you want.
