Basics of Photography
If you are interested in learning the art of
photography, you'll want to use a 35-mm camera
with no automatic aids. That way you have
complete control over how your photos will look.
Much of the art of photography is about
capturing light. To get a good photo, you need to
know how much light to let into the camera. Too
much, and your photo will be a pale image of
what you wanted. Too little, and it will be overly
Getting just the right amount of light for your
photo depends on three factors. First, there is
the type of film. Films come in different
"speeds," which refers to how quickly the film
reacts to light. The usual film speeds are 60,
100, 200 or 400. The slow films, such as 60 and
100, require more light and are used when
shooting outdoors in bright conditions. When
taking pictures in dimly lit areas, such as
indoors, a fast film is the appropriate choice.
These films don't need much light. You should
use a fast film for moving objects, as well. Fast
film will help produce a crisper image.
The second and third factors are shutter
speed and the size of the lens aperture. Think of
a camera as a box that protects the film from
light. The more light that hits the film, the lighter
your photograph will be. Light comes into the
camera through a round opening, called the
aperture, that can be made bigger or smaller.
The aperture is covered by the shutter. When
you press the button to take your photo, the
shutter uncovers and then covers the aperture,
letting in the light. When you change the speed
of the shutter, you change the amount of time
that light comes into the camera. To expose your
film to the right amount of light, you need to
adjust the shutter speed and the size of the
aperture. For indoor shots where you need a lot
of light, you can use either a larger aperture or a
slower shutter speed. For daytime shots outside
in bright sunlight, you can use a smaller aperture
or a faster shutter speed to reduce the amount
of light entering the camera. In addition, if you
want to take a picture of moving objects, you'll
need to use a faster shutter speed - otherwise
the image will blur.
