摘要
The scene is to be photographed through a fish-eye lens which provides the transformation y = c sin THETA, where c is a constant, THETA the zenith distance of the point considered, and y the distance of the image of the point from the image of the zenith. The resulting diapositive is to be projected on to a spherical (hemispherical) surface. Projection may be either in to the convex or the concave side of the surface, and is preferably on to a transparent 1 m hemisphere, on the side remote from the observer.
