#shutter speed

This is done by adjusting key photography elements whether in-camera (ISO and Shutter speed) or off-camera (Aperture). Shutter Speed If Aperture controls how much light comes in, then Shutter Speed dictates the amount of time that the film or sensor is exposed to the light. Shutter speed is measure in seconds which correlates to the time it takes for the whole cycle (opening and closing of the shutter) to complete. In practice, the sensor/film records all the light, as well as movements, from the time that the shutter opens until it closes. This means that by shooting at faster shutter speed (half a second or faster) you’re actually letting in less light as opposed to having the shutter open for a second or longer. Oftentimes, shutter speed is set to less than a second in order to freeze a moment and/or avoid motion blur caused by either unsteady hands during handheld shooting or moving subjects. There are, however, some instances where a slower shutter speed is required to produce the desired result (as seen in the image below) or what is commonly called as long exposure. • For handheld shooting, try not to go below 1/20 shutter speed as to not cause motion blur.
