One of the things I have always loved about cameras is the sound they make when you press the button to take a photograph.. Click, Click, Click, Click.... I love that sound in quick succession.... The Shutter is responsible for that noise..
SHUTTER SPEED: The speed at which the camera's shutter opens and closes as the photograph is taken. Shutter speeds are generally measured in fractions of a second, with a one placed over the shutter speed number to form the fraction. For example a shutter speed of 500 is actually 1/500 of a second.... Now what does that really mean??
The shutter opens and closes to allow in light... A fast speed will Stop action and a slow speed is used when there is not a lot of light...
A high number indicates a FAST shutter speed wich will allow less light in... Want to Freeze action, use a High Shutter Speed..
A smaller number will allow more light into your camera. Want to taake a photo of a person in low-light use a slower shutter speed ..
FYI: Use a tripod for a shutter speed slower than 50mm... Otherwise, you may end of with a blurry picture..
