Rob,
Verrry Nice! For fun try holding down the mouse and panning through
the QTVR at ever increasing speeds.
Did you have to use a specialized tripod head to make this image?
Again a fantastic job Rob.
Thanks Jay,
The head is a standard 3 way unit but with the addition of a macro slide rail
which is fitted with a QR plate and shoe so that I can clip it in between the
tripod head and camera. This then allows me to add a horizontal offset to allow
the pivot point to be set at the lenses optical nodal point in order to
minimize parallax errors.
Where do you get info about a particular lens' nodal point?
Cheers,
Rob Studdert
