Hi Destiny and welcome to the forum,
Great to get to know that you are happy with your new equipment. Nice you are number 1! Got mine yesterday evening. Of course I tried it at once. Steps on in the NN Fanotec quality program. I am happy with these products since years.
Using the Nadir Adapter is not a very tricky thing. What sort of equipment do you use? Camera lens combination?
Anyway: first of all you have to measure the
Pivot Distance: the distance from center of RD16 to center to fixing screw of the nadir adaptor, the turning point of the adaptor. First nadir shot: -90º with closed adaptor. Then move the tripod sideways in direction of third leg by 2x Pivot Distance. Just use the third leg to adapt your distance. Open up the nadir adapter and shoot the second nadir shot.
This will only work when you use a special set up of NN4 RD16 to your tripod. The lower rail has to be set to 90º to the "two front legs of the tripod". And it has to be "in line" with the third leg. Otherwise you can not mask out the tripod in a proper way.
The first nadir shot will show the tip of the third leg of the tripod on the left side. Important area! The second Nadir Shot will show the corner of the nadir adapter between the two legs of the tripod on the right hand side of the picture. Second important area! When you mask and stitch the two nadir shots, you have to check that there is space between the corner of the tip of the third leg and the corner of the Nadir Adapter. If they touch, move the tripod beyond 2x Pivot Distance. If it is far beyond the old position of lens axis - center of Rotator in N1 - may be you have to use a "viewpoint correction"
Most of us use PTGuiPro. You can download a trial at
www.PTGui.com. Just load the two nadir shots, in same orientation, go to >mask, and mask out the tripod. Then stitch. Check if there are black or checkered areas left in the two important areas. Then you have to move the tripod beyond 2x Pivot distance.
