What is shutter speed?

   It is essentially the      1/8000,
    indicator of the            1/4000,
    duration / timing          1/1000,
    at which the               1/500,
    shutter curtain             1/250,
    opens up and               1/125,
    closes during an           1/60,
    exposure process           1/30,
                               1/15,
                               1/8, 1/4, 1/2, 1 etc.
Shutter speed dial

   The shutter speed dial provide the selection
    of shutter speeds, and indicates the timing of
    the shutter open and closes.
   A fast shutter speed such as 1/500 sec will
    close faster than, say 1/2 sec exposure time.
    In this case, the shutter curtain will close very
    fast and thus resulting in less light entering
    the film.
What does shutter speed do ?

   Different shutter speeds yield different kind of
    visual effect on a final photograph.
   A fast shutter speed can freeze action
    while slow speed can blur your image

What is Aperture?

   The aperture is like a pupil in your eye. The pupil
    opening is bigger in a room with less light to allow you
    to see and Vice Versa.
   In Photography, Aperture is referred to lens
    diaphragm opening inside a photographic lens.
   The size of this diaphragm opening in a camera lens
    REGULATES amount of light that passes through onto
    film inside the camera.
   The size of an aperture in a lens can either be a fixed
    or adjustable type (like an SLR camera).
How is aperture calibrated ?

    Aperture size is usually
    calibrated in f-numbers. These
    are ratios.

   i.e. f 22 (f/22), f16 (f/16), f/11, f/
    8.0, f/5.6, f/4.0, f 3.5 ,f/2.8,
    f/2.0, f/1.8 etc.
What it means is
   f/16 will let in 1X the amount of light than a
    diaphragm opening of f/22 and so forth;
   f/4.0 will let in 1X lesser than that of f/2.8 etc.
   Aperture + Shutter Speed = Exposure
   Aperture, along with duration/timing of shutter curtain
    opening, BOTH contribute to a the formation of an
    exposure.
   Aperture also affects "depth of field"
Exposure

   Balancing Shutter and Aperture:
    Exposure is about different combinations of
    shutter and f-stop settings. These
    combinations can drastically affect the
    finished picture.
