The importance of a robust, sturdy tripod cannot be
overstated. Interior photography inevitably necessitates long
exposures – for which a heavy-duty professional tripod is
essential. Both the changing of film backs and pulling out
exposed sheets of instant-print film are substantial, jerky
movements throughout which the camera must be held rocksteady
to avoid even the slightest displacement from its
critical position. Resetting a camera position if it has been
displaced for any reason is a time-consuming and frustrating
business, as it involves rechecking all the settings, including
the focus.
Professional tripods are made up of two parts: the head
and the set of legs, both of which are bought as separate items
to suit the purpose for which they are required. A good head
and a good set of legs are each likely to cost a similar amount,
so allow for this when making your choice.
Though usually a little more expensive, it is best to buy
a black tripod as this eliminates the problem of its reflection
in glass or other reflective surfaces in the picture. Other than
being sturdy and black, check that the legs (including the
central column) extend to a height at least as high as your eye
level and preferably somewhat higher for extra flexibility.
Screw tighteners, rather than clips, for locking the legs in
position are also a sensible choice as they avoid any
possibility of a clip snapping off. The legs should have rubber
feet to prevent the possibility of any instability from slipping
or sliding on a smooth floor.
With regard to the head, it is essential for it to be heavy
and to have plenty of available movement in the three
dimensions, with large hand-sized handles with which to
make necessary fine and tight adjustments. It is also useful to
have the movement in each direction calibrated in degrees of
angle: by zeroing everything, the operation of roughly setting
up the camera in the first instance is speeded up; and if
different critical angles of a view need to be taken this
calibration makes it possible.
Finally, a quick-release plate is another handy, timesaving
device much to be recommended. It consists of a metal
shoe that is screwed firmly into the base of the camera, and
simply clicks in and out of the socket on the tripod head.
