The Shutter Speed function, is what determines the length of time in which the camera's sensor is exposed to the available light source. Hence, the longer the shutter is open, the greater amount of time the sensor has to gather light. In low-light settings a longer shutter speed is typically required to ensure correct exposure, by allowing more light to reach the camera sensor.
Often, shutter speed and frame rate are referred to in the same context, however, the frame rate indicates how many frames are captured per second, whereas the shutter speed simply refers to the amount of time in which a single frame is exposed for.
One of the major influences on the sharpness of an image, is based on camera shake and the subject's movement (Slyvan 2012). This means that a lower shutter speed is allowing more light from the subject into the camera, therefore their movement may appear less sharp, or may even produce blur. A greater shutter speed will produce less blur and capture more sharply.
In my own examples, I used two different shutter speed settings. the first video was shot using a shutter speed of 50, whilst the other one was set at 125.
Overall there is a visual difference between the two shots, particularly in terms of clarity. The first shot does not depict each feature of the water and its movement so explicitly, whereas the following clip shows greater detail and sharpness.
As I was adjusting the shutter speed, I had to ensure that each video was exposed correctly, therefore altered the ISO and aperture settings accordingly.
