It
is always a good idea to begin from a neutral position
with all the camera planes parallel and no camera
movements. In this illustration, the camera
has no movements in use and is pointed slightly
down to the center of the cube. There is an expected
convergence to both the top and bottom of the cube.
We will follow through a sequence of movements and
the perspective effects on the cube. Remember, wide
angle lenses exaggerate the optical changes.
We might use this for copying 2 dimensional art works
or where all three planes are parallel. We could also use
it where the aperture used for the exposure gives the desired
depth of field.
