Macro Photography
By: TJ Tierney
Exploring
the world of miniature objects with a macro lens is
a special and exciting area of photography, and once
you start, you will quickly become addicted. The
world of macro photography holds many delights and
is an area that cannot be appreciated with the human
eye.
Macro photography is the name given to close-up
photography, and is best explained as images that
are taken at reproduction ratios of life-size and
above. Ratios of between 1:7 and 1:1 fall
into the macro photography category.
Understanding Ratios: This is a term used to
express the magnification of a macro lens or other
macro equipment that relates the real life-size
object to the reproduction size on a slide or
negative. If you shoot an object that is 3cm in
length and it measures 1.5cm on a 35mm slide or
negative - the ratio is 1:2. When both are equal
length the ratio is 1:1
Choosing the right lens is the most important factor
with macro photography. While a telephoto lens may
be acceptable with some types of close-up
photography, the macro lens is invaluable to get
really close and really accurate focusing.
There is an endless range of subjects that fall
under the range of macro photography. The most
common subject for macro photography is the natural
world - all types of flowers, plants, and insects.
For the more creative photographer, macro
photography is used in abstract imagery.
With many forms of macro photography, especially
with insects, a lens with a long focal lens -
minimum 200 mm is required for some nature subjects.
You need to keep a working distance from the subject
to get a successful image - you don’t want to
frighten your subject away.
When
shooting close-ups you are limited with
depth-of-field - to get an attractive image you must
focus on the most important part of the subject.
This will be achieved easier if you place your
camera on a tripod or monopod.
By using your tripod you will reduce the risk of
camera shake. Subject movement is also an important
factor to consider. Macro photography magnifies the
subject, leaving more room for blur. A strobe unit
can be used to freeze movement - even on the
brightest of days you should consider using your
strobe unit. Try bouncing light from your strobe
unit off a reflector. This will give your image a
softer illumination.
Many amateur photographers stay away from macro
photography because they feel that their technical
ability is too inept - your personal ability should
not turn you away from this exciting part of
photography - macro photography is like all types of
photography - practice makes perfect.
