5.1 Nodal point (continued)
Now read the B-value off the nodal rail (in mm):
Enter the exact B-value (in mm) in the software.
Confirm with "next".
This procedure must be repeated every time a new camera/lens/focal length/focusing
combination is used.
Setting the correct nodal point is essential for successful stitching of the images.
If the nodal point is not correctly set, it may be that the panorama cannot be stitched
and that it is necessary to repeat the image capture.
When detaching/reattaching the digital camera there is a risk that the zero position of
the camera changes. Make sure that you always attach the camera at the very same
position. Slide the camera body to the rear metal base to make sure that there is no
deviation.
When using larger cameras with larger lenses the nodal bench rail may not be long
enough. Instead of sliding the zero position of the camera on the rail we strongly
recommend to use a second – larger – nodal bench rail for long lenses and attach the
camera always at the very rear metal base. This avoids any potential error when using
different cameras/lenses.
