CONTROLLING THE AMOUNT OF LIGHTSHUTTERControls the amount of light by the length of time it remains openAPERTURE(size of the lens opening) controls the brightness of light that reaches the film
Shutter speed is simply a measure of how long the shutter stays open when you take your picture. shutter speed is measured in fractions of seconds. the faster the shutter speed, the less light will hit the film.
SHUTTERLeaf Shutter Located inside the lens
SHUTTER SPEED Slow shutter speed Fast shutter speed
subject and background are frozen fast shutter speed (1/500, 1/1000, 1/2000 second) peak of action
blurred subject, frozen background slow shutter speed (1/15, 1/8, 1/4, 1/2 second) brace the camera!
frozen subject, streaked background slow shutter speed (1/15, 1/30, 1/60 second) camera moves with the moving subject
PanningMove the camera with the subject as it crosses the field of view of your camera, and you snap the shot as you move the camera with the subject.
SLOW SHUTTER SPEEDBLURRED ACTION (1/15, 1/8, 1/4, 1/2 second)
FAST SHUTTER SPEEDSTOP ACTION(1/500, 1/1000, 1/2000 second)
SLOW SHUTTER SPEEDPanning During the exposure, the camera is moved in the same direction as the subject.Resulting in a reasonably sharp subject and a blurred backgroundPANNED ACTION (1/15, 1/30, 1/60 second)

APERTUREEach f/stop number can be though of as the bottom part of a fraction
The larger the f/stop number, the smaller the lens openingf/11 is a smaller opening than f/4 Each full stop aperture setting allows half or double the amount of light as the next onef/1.4f/2f/2.8f/4f/5.6f/8f/11f/16f/22
APERTUREThe area from near to far in a scene that is acceptably sharp in a photograph
DEPTH OF FIELDThe smaller the aperture size, the more that a scene will be sharp from near to far (deep depth of field).The larger the aperture size, the less that a scene will be sharp from near to far (shallow depth of field).
f/22 provides more depth of field than f/4

SHUTTER and APERTURETo get a correctly exposed picture, you need a combination of shutter speed and aperture
Each shutter speed lets in twice as much light as the next faster speed1/60 lets in 2x as much light as 1/125Each aperture setting lets in twice as much light as the next smaller opening (larger-numbered setting)f/4 lets in 2x as much light as f/5.6
