TILT AND SHIFT ADAPTER
Camera positioned level. The roof of the building is outside the area
projected onto the sensor (HC28 + HTS).
The camera positioned level again with an upward lens shift of
9 mm applied results in parallel verticals.
The complete camera tilted upwards to include the top of the
building results in converging vertical lines in the image.
USE OF SHIFT
For perfect parallel vertical lines in
the image, the camera needs to be
parallel to the subject. Tilting the
whole camera would produce con-
verging parallel lines. But by shifting
the lens parallel to the image plane,
you can raise or lower the view with-
out tilting the camera. If the subject
is a building as in this example, the
camera should be placed level.
