The aperture is a hole whose size can be varied to allow more or less light to pass through it. APERTURE The smaller the f-number is then the larger the aperture is and the more light it will pass.

the length of time a camera shutter is open. in digital photography shutter speed is the length of time that your image sensor ‘sees’ the scene you’re attempting to capture. SHUTTER SPEED
Shutter speed is measured in seconds – or in most cases fractions of seconds. The bigger the denominator the faster the speed (i.e. 1/1000 is much faster than 1/30). SHUTTER SPEED
Shutter speed is measured in seconds – or in most cases fractions of seconds. The bigger the denominator the faster the speed (i.e. 1/1000 is much faster than 1/30). SHUTTER SPEED In most cases you’ll probably be using shutter speeds of 1/60th of a second or faster. This is because anything slower than this is very difficult to use without getting camera shake. Camera shake is when your camera is moving while the shutter is open and results in blur in your photos.
Shutter values follow a standard sequence with each one being half that of the next, allowing half as much light to pass through. SHUTTER SPEED 1sec; 1/2sec; 1/4sec; 1/8th; 1/ 15th; 1/30th; 1/60th; 1/125th; 1/250th; 1/500th; 1/1000th; 1/2000th When a camera shutter is open, any objects, persons, etc. in front of the lens are recorded on film. Anything that moves across the field of view while the shutter is open will be recorded as a blur.
