Digital Photography - Camera Tripods
If you want to take great
pictures,camera tripods are a necessity for
you. Tripods can helping to minimize camera movement
which can cause an image to blur.
Blurring is
particularly conspicuous in photographs taken with
extended exposures (for instance under low-light conditions)
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
awkward 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.
Conventional 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.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 camera tripods come
equipped with levels, but they are also available as
inexpensive accessories.
