A picture is exciting because it shows something
extraordinary. This can be achieved by an exciting subject or a more or
less sophisticated photographic technique. However, it is also possible
just to exploit the special physical characteristics of a lens. Especially
ultra-wide lenses offer some interesting possibilities. Such effects like
the ones shown below are too extreme for regular usage so handle them with
The easiest way to push the perspective
to the extremes is to use a fish-eye. It is really nothing more than a special
purpose lens which cannot be used for much more than effect photography.
A fish-eye is basically an ultra wide lens which does not correct any of
the natural distortions. The picture below shows a typical result. The
effect is emphasized if you point the lens either up or down.
The following pictures show quite extreme
perspectives with a normal ultra-wide lens. The picture to the left demonstrates
how to decrease the size of a huge object (here Ayer's Rock/Uluru) just
by emphasizing the even bigger sky. Have a look at the interesting effect
on the clouds here- the sky seems to get bended! With ultra wide lenses
closer objects seem to grow while objects in the distance seem to shrink.
That also happened to poor Martin in the picture to the right. The legs
and feet are very small compared to the face and the breast. Maybe you
shouldn't use this kind of composition for your new girl friend. :-)
