Setting the Exposure
Effect of Aperture and Shutter Speed
Correct exposure of the subject is determined by the combination of shutter speed and aperture setting. There are many correct combinations of shutter speed and aperture for a particular subject. Different combinations produce different effects.
Effect of Shutter Speed
The shutter speed determines the length of time that light is allowed to strike the CCD. 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.
A faster shutter speed also helps preventing camera shake.
