-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Jan,
for completeness: On a full format sensor 70.81 deg (vertically) should be f=16.9mm. The lower 5 pictures should be down 21.22 deg, the other 5 up 21.22 deg. Horizontally they should be spaced at 72 deg in each level. All these 10 pictured would be landscape. If you do portrait you'd need f=15.7mm or less. The single down facing pic needs to be parallel to one of the pics in the lower ring. The analogue holds for the up facing photo. (All of that is untested.) cheers, lukas On 09/10/15 23:23, Wirz wrote: > Hi Jan, > > Based on what wikipedia says about regular dodecahedra and pentagons and > after some scribling: > Seen from the centre of a regular dodecahedron the height of one of the > faces has an angle of 1.24 or 70.8 degrees.
