A major problem in many presentations is an overwhelming usage of
wide-angle to normal lenses. Monotonous perspectives are rather
poisonous from a viewer's perspective so don't forget to add some extra
spice by taking advantage of tele lenses. Tele lenses are often used to
isolate or emphasize an object (e.g. portraits, sports or wildlife) but
there's more than just that. In contrast to the impression of depth provided by a
wide-angle lens a tele lens can "compress" a scene or isolate or special object.
The first picture illustrates how a tele
lens can compress the several layers of the scene to a relatively "flat"
view with a seemingly shrinked distance between the layers.
The next picture illustrates that this also works pretty well for landscape photography as well.
Technically compression is a function of distance and enlargement. The bigger
the distance and the higher the enlargement (=longer focal length) the more
pronounced is the effect. However, even moderate tele lenses a la 85mm or 100mm
are already good enough in many situations.
