What is a shutter speed in Galaxy Camera?
Shutter is the device on the camera that open and close to control how long the focal plane is exposed to light.
The camera’s CCD samples light for an appropriate length of time, and then shuts off.
Shutter speed refers to the amount of time it takes to open and close the shutter, and it is an important factor
in the brightness of a photo, as it controls the amount of light which passes through the aperture
before it reaches the image sensor. Slow shutter speeds allow more light in, but moving subjects may blur.
Faster shutter speeds allow less light in, but moving subjects are clearer.
