selection - affect on perspective
Lens selection for a subject can have a crucial effect on
visual representation of a subject.
Initially for the Architectural Sites
of Contestation project I used a 135mm lens with
a 6x6 format camera. But as the project was centred on building
sites with acute angles, I experimented and found that a 40mm
lens gave a far more dramatic effect. While the 135mm lens
gave the building a realistic proportion it flattened off
the acute angles the buildings sat on an made then look closer
to a right angle.
If we photograph an object, say a gazebo, from the distance
with a telephoto lens we can fill the frame with the gazebo.
Then if we photograph it from the same spot with a wide-angle
lens, the gazebo will appear quite small in the frame and
we will have the wider setting that it is placed in as part
of the image. But if take the wide-angle lens shot and we
crop and enlarge up the section with the gazebo in to match
the telephoto image, we will see that the perspective is actually
the same. That is the vertical and horizontal lines running
off to a vanishing point. The enlargement would of course
give us a very grainy or low-resolution image, and normally
if we were using a wide-angle lens we would step forward to
fill the frame. So, it is this change of camera viewpoint
to the subject, which alters the perspective, not the lens.
