Ewen Whitaker and William Hartmann (pictured), and others produced a lunar atlas of “rectified” images. Since no craft had yet orbited the Moon, photographs of the Moon from Earth were projected onto a globe, which was then photographed from different angles. This technique eliminated the effects of foreshortening, and craters that appeared distorted and elliptical near the Moon’s limb were rendered circular on the resulting maps.
