With an RS-1/D800/16mm/nadir adapter, I've been trying 6 shots around at 90 degrees, 1 nadir and 1 zenith at -90 and +90 respectively but I'm less than satisfied with the results. that pattern requires lots of photoshop on the nadir and it's sometimes a struggle to stitch the zenith because there's not much there besides sky. I've tried 6 shots around at -30 and 6 at +30 with one nadir and it stitches much better, but that many shots seems inefficient to me. It also requires better masking tools than the ones in the current version of autopano.
Can anyone suggest other shooting patterns that might work better?
