Im just new kid starting into field of VR. I have rented 360Precision Adjust Head with Canon 14mm Rectilinear lens & 5D Mk II.
I have read an article stating it is possible to create fully spherical VR with just 8 shots using this equipment. I have got PTGui & Pano2VR softwares.
My problems are following –
PTGui is really bad at automatic alignment of images & it requires minimum 12 images to do the job. Also when I tried shooting 6 straight(lens parallel to horizon) & 1 zenith & 1 Nadir shot, there were 6 blank squares in stitched VR.
Kindly suggest a best way to create a VR with Minimum number of shots required.
Thanks in advance.July 1, 2015 at 6:28 am #6289

this article suggests full sphere with 14mm rectilinear can be done, but it is a bit tricky –
i shoot w different gear, but PTGui always does a great job for me w auto align assuming sufficient overlap and detail and NPP (no parallax point or “nodal point”) is set properly etc, if you are having problems check that the NPP for your camera+lens is set properly, as per the video below
if you want to shoot 360° VR panoramas with fewer shots, use a fisheye lens between 8mm and 16mm, typically a full sphere is covered in 4-6 shots around plus zenith and nadir depending on focal length
the following fisheye lenses are all good choices for shooting full 360° x 180° spherical VR photography on full frame DSLR –
Samyang (Rokinon) 8mm f/3.5 Fisheye
Samyang (Rokinon) 12mm f/2.8 Fisheye
Tokina 10-17mm f/3.5-4.5 Fisheye
Canon 8-15mm f/4L Fisheye
