I don't think I have to compensate for the
curvature of the mirror. The device comes with
special software that 'unwarps' the resulting
image, and makes it into a (QuickTime VR)
panorama.

I might want to use a screw on close up lens so
that I will be able to completely fill the film
with the image of the mirror. How big is the
distortion caused by these lenses?
