Shutter Speed

By , April 24, 2010 7:28 pm

The shutter speed controls controls the duration of light. The length of time is the shutter speed and it is measured in seconds. 1/30 second, 1/250 second, 3 seconds, etc. On the T1i the shutter speeds range from 30 seconds to 1/4000 second when you shoot without the flash. There is another feature in the manual mode called bulb exposure. It lets the shutter stay open indefinitely as long as you press the shutter button. If you use the built-in flash, the fastest shutter speed in 1/200 second and the slowest ranges from 1/60 second to 30 seconds depending upon the exposure mode.
