DIFFERENT LENS EFFECT
2. PERSPECTIVE
Consideration
of
per-
spective
when
taking
photos
from
various
distances
and
keeping
the foreground the same
size.
The above photographs show the different effects obtained by using various focal length lenses. Using
the same foreground subject, variations in the size and depth of the surrounding objects arc produced.
Looking at these you can see that with the same subject, there is a different background effect in each
case. The shorter the focus length of the lens, greater is the exaggeration in the appearance of the
foreground in relation to the surrounding area. Again there are marked differences in the degree of
the background. With the long distance lens, the background area is stronger and clearly adjusted in
relation to the foreground giving an effect of solidness to the picture. Again, according to the
size of the lens opening, there are differences in the depth of the object being photographed. This
has advantages, for instance, in producing different effects with background focus, or in using a
maximum opening lens to facilitate taking pictures under unfavorable conditions. By selecting the
appropriate lens and by taking advantage of its characteristics, you can improve the excellence
of your picture.
