7.13 Roll adjustment
Position a tall thin vertical real object and a similar virtual object so that they
line up (zoom out so that their entire length can be seen). If necessary adjust
one of the objects until they appear to be parallel. Now view the objects from
a diametrically opposite direction (ie, such as the camera’s pan angle is 180
degrees from what it was before).
If the objects no longer appear to be parallel, the free-d ™ camera needs to be
rolled clockwise or anticlockwise (ie, around the Y-axis). This can be achieved
by rotating the ‘wedge rings’ which form part of the base plate of the camera,
although the tilt and roll cannot be adjusted independently by this means.
