Tripods
are a necessity for anyone who wants to take the best pictures
possible.
They
are useful for many different situations by helping to minimize
camera movement which can cause an image to blur. |
Blurring
is especially noticeable in photographs taken with extended exposures
(under low-light
conditions, for example) and becomes more apparent when photographs
are enlarged. Even slight motions of the camera can cause blurring.
Supporting
the camera can help to reduce camera movement. A tripod provides
the best support, but cameras can also be stabilized with objects
such as doorframes or tree trunks. Monopods are suitable for outdoor
use when tripods are either too heavy or too cumbersome to set up.
There
are hundreds of tripods to choose from in a broad range of prices.
The most expensive ones are made of composite materials such as
carbon fiber which is lighter and more durable than either aluminum
or alloy. Expensive tripods are usually equipped with quick release
mechanisms for adjusting the legs and the camera mount.
Each
tripod has three heights which must be considered -- maximum, minimum,
and collapsed. For most purposes, the maximum height should allow
you to use the camera at a comfortable standing position. You rarely
need a tripod higher than this. If you do a lot of close-up work,
the minimum height is an important measurement, although extensions
can be added to the head which allow the camera to be brought close
to the base of the tripod. Finally, the collapsed height is important
to determine the tripod's portability -- compact tripods are usually
easier to carry around.
Tripods
usually have a center column to attach the tripod head. This center
column can be used for fine height adjustment and some models allow
the camera to be tilted down towards the ground for closeup work.
Look for a center column with a hook – these can be used to
hang heavy objects for increased stability.
Tripod
heads are the part of the tripod that the camera attaches to. They
allow the camera to swivel and move up and down. This movement is
accomplished with two basic types of head – the three-way
pan tilt head, and the ball head.
Traditional
heads are the three-way pan tilt type. They have three different
axes and each is controlled with its own mechanism and lock. The
locking mechanisms make this type of head ideal for situations where
precise control of the visual field is needed, but can be inconvenient
for other uses.
Ball
heads allow all three axes to be set at the same time, so they are
easier to use. They are also more expensive but most photographers
gladly accept the higher price for the increased flexibility in
camera movement.
Monopods
are an ideal alternative to tripods where portability is a concern.
They consist of a single support which the camera is mounted on.
Outdoor photographers often prefer monopods over tripods because
the latter are bulky and difficult to set up.
Using
a monopod is almost as easy as pointing and shooting. The monopod
gives the camera the extra stability necessary for good quality
shots.
Carrying
a tripod is easier with a case or a carrying strap. Cases can be
used to hold all your camera equipment but are bulky to carry around.
If you don't have a lot of equipment a shoulder strap is the best
solution for carrying the tripod.
If
the camera needs to be perfectly level, small bubble levels can
be attached to the tripod. Some tripods come equipped with levels,
but they are also available as inexpensive accessories.
