2.1 Setting up the VR Drive Panorama Set (continued)
Step 8: Setting the digital camera
Connect the release cable
into the camera and plug it into the socket for the release
cable (1) on the VR Drive. Make sure that the
plug points to the back of the camera
and not to the front, as otherwise it may be visible in the image for spherical images.
As light and distance values in a 360° rotation vary greatly, the
automatic light meter
and autofocus of the digital camera must be turned off
.
Set the exposure to manual
and select an average light reading.
Focus manually on the lens
, selecting an
intermediate focusing distance
.
The VR Drive and the digital camera are now ready for image taking.
Setting up the VR Drive Panorama Set is important to obtain the best
possible precision and ease in digital stitching. Note the C-axis values
(nodal points) for different focal lengths in the following table:
