Wow! Very impressive demonstration of concept. Beautiful spot for panoramas
and amazing results without either retouching or nadir fixing.
I was letting alll this "laser this and that" go past me, thinking all
the while "not for me..." but now I think I'll have to check it out.
Especially as I prefer handheld to monopod and monopod to tripod. I
guess it would be more difficult for panoramas that require more shots
to square the circle--like the 10.5mm Nikor on my Fujifilm S5 Pro,
which requires six around plus up and/or down...
