Shutter Speed is the common term used to determine how long the camera’s shutter is open for when taking pictures and/or filming, and at what speed. If the camera is using a slow shutter speed, then the exposure time will be longer. Shutter Speeds are defined by how long they are used for, so when selecting what shutter speed you want to use, the shutter speed will be presented as a fraction of a second. So basically the shutter speed is about how long the sensor see’s what image you want to capture. If it is a slow shutter speed, then the image will be clear, but if it is a long shutter speed, then the image will be unclear, delayed and blurry. The shutter speeds usually double as you gradually get higher and higher. The standard shutter speed is around 1/60 (1/60th of a second).
