Re: Making Spheres From Panoramas w/Roundshot

yes, and for those of who might
have used twin lens rolleis in the long, long ago this is how they corrected
for parallax when using proxars which exceeded rollei's under the glass
parallax correction for the main lens. simon

I have a simple el cheapo solution to getting a bigger

Edmond Scientific sells "wedge prisms". They are used
for bending lasers. It is a filter like attachment
that allows you to look 10 degrees up, then 10 degrees
down, so you get 20 degrees wider view on your
roundshot. They cost about $50 as I remember.

Every Roundshot owner should have one. With it you can
shoot bird's eye views. Put the camera up high and you
can shoot down in 360 degrees.
