Detail
The photographer can communicate more about the natural environment than just with images
of the broad landscape. With more than one image cable of being stored on a memory card the
photographer is not restricted to making a single carefully chosen statement about a natural
landscape on a particular day. With keen visual awareness and close observation the photographer
is able to move in close, isolate particular features, and build a more detailed impression of a
location. By moving in close, depth of fi eld is reduced, so aiding the photographer’s attempt to
isolate single features within a complex environment.
Macro
Very small features may be photographed with the aid of a macro lens or a relatively inexpensive
close-up lens. The close-up lens is screwed onto the front of an existing lens like a fi lter and is
available in a range of dioptres. The photographer using macro capabilities to capture nature
should be aware of the very shallow depth of fi eld when shooting at wide apertures. Photographers
using the smaller apertures can incur a number of problems. Extended shutter speeds may require
the use of a tripod or monopod and any wind may cause the subject to blur.
Monopods are preferred by many who fi nd the speed advantage over a tripod invaluable. An insect
visiting a fl ower is often gone by the time the legs of a tripod are positioned. Many photographers
specializing in this area of photography often resort to using wind breaks to ensure that the subject
remains perfectly still during an extended exposure. These wind breaks can be constructed out
of clear polythene attached to three or four wooden stakes so that a natural background can be
retained. One or more of the sides can be a white translucent material that can act as a refl ector
or a diffuser to lower the contrast of harsh direct sunlight.
