To position the camera, an 11 x 14 mirror is clamped in the upright in
place of a painting. The camera position is adjusted until the reflection
of the lens seen in the mirror is centered in the camera viewing screen.
At that setting, the lens axis is exactly perpendicular to the plane of the
mirror so there will be no "keystoning" of the rectangular pictures.
