Here is a 3 shot for you to look at
Well, I finally had some success with PW3. I put all the technical setup data on my demo page. Essentially found (again) the nodal point to be at 67mm. Shot 3 portrait shots. Used AE Lock and set the white balance to incandescent. Brought them into PW3. After several trials we finally got one that matched up rather well. But still had blending (none) and you can see small coloration differences. Mismatch factor was 0.1949.
Center is not always center.
One thing I found is that PW does some anticipated math work to determine the CENTER POINT of Height and width the Y and X of the black rectangle. Typically, no two Nikons with the Fisheye have the same center of the circle image. I have seen FE 1' s that the circle was barely cropped off one side.. meaning a center of this image would be off center of the estimated center of the box. This requires manually tweaking and relocating the circle X width center within the width of the rectangle width.
PLEASE WHEN VIEWING THIS PAN - disregard the MESS. We tend to get messy when testing for nodal points and stitching.
The quality of the image is LOW because I stitched at 1400 x 700 dimensions about 80kb . Typically we shoot at twice that dimension to keep more pixels better detail. For this session we were only interested in stitching and blending.
Will let you know more when we learn more.
