The camera has to be a Single Lens Reflex - SLR. The SLR allows viewing
of the subject through the taking lens, and is available in a number of
formats. By far the most popular is the 35 mm. SLR, of which there are
literally hundreds of types about, ancient and modern !

Many people will already own such a camera, or have access to one in
their circle of family and friends. Most models will do the job, but a
more modern version with auto functions can be a great help in some
circumstances. It is also better, as you will see, to have a cable
release, or delayed action available, and a range of slow shutter speed
at 1/30 th. second and slower.


The delayed action device, normally used to include the photographer in
the picture, also helps to obtain sharp results at slow shutter speeds.
As the intention here is to produce prints, or colour slides of computer
graphics, which are likely to remain still, the delayed action can be
set, and triggered when all is ready. There will be a resulting pause of
about 10 seconds before the shutter fires. In this time, as long as the
camera/tripod combination is not touched, all vibrations will die down,
and a very sharp picture can  result.





Obviously, some colour slides of graphs, titles etc. from your computer,
could enhance private of business presentations considerably.
