Finding the Nodal Point
with 3rd Party Lenses
How do I Locate my Camera’s Nodal Point?
Follow these steps and you will be able to easily locate the nodal point
for any camera and lens combination.
Simply put, the nodal point is the point inside your camera where the
light rays converge and flip over. When shooting an immersive pan-
orama, it is necessary to rotate about this point to eliminate the im-
age mismatch caused by parallax error.
Parallax error can be easily demonstrated by this simple experiment.
Close one eye and hold your index finger upright about six inches
away from your open eye. Rock your head from side to side. Notice
how your finger moves with respect to the background. This relative
movement is due to the fact that you are not rotating your head around
your eye’s nodal point, which is somewhere in the center of your eye-
ball. Instead, you’re rotating about your spine which is several inches
to the rear and off to one side. It is this relative side-to-side motion
that we will strive to eliminate when setting up a camera for VR pan-
oramas.
The Side-to-Side Adjustment
Your KiWi head is designed for a specific camera. The side-to-side
adjustment that is normally required for universal models, such as
our KiWi+ is not needed.
