After the picture is taken, the film is impregnated with the chemicals required for processing the image and the picture begins to appear only seconds after the shutter is pressed; development is complete within minutes. As well as providing an immediate image of the subject, these cameras also offer as many possibilities for creative photography as their conventional counterparts. Many professional photographers attach special Polaroid backs to their standard cameras; once they have composed the image and calculated the exposure they will take a Polaroid picture to ensure everything is perfect before shooting on conventional film. Polaroid backs are available for all cameras from 35 mm size to 10 x 8 models.

The Video Still Camera

The video still camera is a relatively new type of camera; it uses a compute disk instead of conventional film and the pictures can be viewed on a television screen or video monitor, or sent away to be made into prints. Although still in its early stages, this form of photography could change the nature of picture-taking in the future.
Some lenses in certain situations have distinct advantages over others. An extra element of challenge can be added to photography by experimentation with different lenses, perhaps applying a particular lens to a situation in which it is not normally used.

Lenses for 35 mm SLR Cameras

Most 35 mm SLR cameras are purchased with what is known as a ‘standard’ lens. This has a focal length of about 50 mm and will give an angle of view roughly equivalent to what we see with our own eyes. Its maximum aperture in the region of fl .8, but faster lenses such as fl .4 and fl .2 are available. At a later date one of these faster lenses could prove useful.

Lens Mounts

All SLR cameras have interchangeable lenses, attached to the camera by means of a mount. There are several different sorts of mount, the most popular being the bayonet mount. This is operated by depressing or sliding a small button positioned on the camera body near the lens. The lens can then be turned 45 degrees in a clockwise direction and pulled gently forward from the camera body, and another lens inserted using the reverse procedure.

Fisheye Lenses

A fisheye lens can be used to dramatic effect, but as an everyday piece of equipment it has limited applications and its novelty value can quickly wear off.

A Macro Lens

The macro lens allows the photographer to get very close to the subject without the need for special close-up attachments. Depending on the lens used, small objects can be magnified to produce a final print which shows them life size. Many of the lenses mentioned here in the 28 — 300 mm range have this facility built in and it is often worth considering paying a bit extra at the outset if this is of interest.
