More Details about Capture Functions
Correct exposure of the subject is established by a combination of shutter
speed and aperture setting. There are many correct combinations of
shutter speed and aperture for a particular subject. Different shutter speed
and aperture settings produce different effects.
The shutter speed determines the length of time that the light is allowed to
strike the CCD, to adjust the amount of light striking the CCD.
• Using slower shutter speed
If the subject is moving, the image will be
blurred because the shutter is open longer.
It is possible to enhance the effect of motion
(rivers, waterfalls, waves, etc.) by intentionally
using a slower shutter speed.
• Using faster shutter speed
Choosing a faster shutter speed will allow
freezing the action of a moving subject.
Even if the subject is not moving, a faster
shutter speed also helps prevent camera
shake.
