Shutter Speed

Shutter Speed is an indication of how much time the shutter remains open. Contrary to the actual term, the unit used here is usually 'second' instead of '1/second' (for example 1/30 second, 1/60 second, 1/125 etc..). The more the denominator, the more is the speed in which the shutter opens and closes (or lower the time shutter remains open). Usually lowest shutter speed for digital cameras is kept at 1/60 or even 1/125. Lesser speed can cause 'shake' in the pictures taken. Sometimes landscape photographers or night photographers use lower shutter speed for taking photos with special effects. Change in ISO for photos, or aperture is usually accompanied by change in shutter speed also to avoid over exposure or under exposure as the case may be. So remember to keep the proper setting in shutter speed when you change the other settings too.
