Lateral Positioning - Rollei 200 Mark II User Manual

6. Positioning of the nodal point

6.2 Lateral positioning

Select a plane that contains a near object "1" and a distant object "2" in the
same visual orientation, in a horizontal direction (Fig . 13) .
1 . Loosen the base fixture (lock) in order to move the camera about the
panoramic axis . Align the camera so that both reference objects appear first
on the left hand side and then on the right hand side of the shot (see Fig .
14 and 15) . Check whether the horizontal distance "X" between the two
objects differs in the two photos taken: The more constant this distance is,
the more precise the lateral positioning of the nodal point is .
2 . To achieve better results modify the adjustment in small increments by
moving the base plate "S" . When the correct position has been reached, it
should be noted from the scale on plate "S" .
Note: Always carry out the adjustment of the longitudinal positioning first . Do not
adjust the lateral positioning until the longitudinal positioning has been defined .
