An exercise: create a 220 megapixel stereoscopic panorama by the single camera method using two rows of photos.

Shooting: 16mm Zenitar fisheye lens on Sony A7r camera; Nodal Ninja Mecha C2 rotator; lens pupil 60mm forward of the axis; 2 rows of 12 views at +/- 25 degrees pitch; 3x1EV exposure brackets.

Stitching: PTGui 12 Pro in hdr mode. Apply centered sector masks approx 45 degrees wide and align;  substitute sector masks offset + or - 30 degrees  to stitch left and right spheres; render with 'exposure fusion' tonemapping.
