This
is an effect that occurs when you are trying to take a full-body shot of a subject
and both you and the subject are standing, but you are standing at a higher or
lower level, so that you have to tilt the camera downwards or upwards slightly.
In this situation, if there are any regular structures, such as buildings, in
the background of the shot, the spaces between the structures will appear wider
at the top and narrower at the bottom when you take a shoot from a higher angle,
or narrower at the top and wider at the bottom when you take a shoot from a lower
angle.
This is precisely the same effect as when you take a picture looking upwards
from the foot of a tall building and the upper floors of the building appear
to narrow due to the difference in the distance from the lens to the upper and
lower floors (tilt). |
