Using a Rolleiflex with a panoramic head, ten negatives were taken that, enlarged and mounted, resulted in a 360° photo.
Leme then addressed the challenge of taking a 360° photo in a single negative.
The demonstration of his eventual solution consisted of a lens mounted in a small, empty tomato purée can, an internal device which is the principle of the invention, and a piece of film fixed inside the can.
In the meantime, sure of having found a solution to the problem of taking 360° photos, Leme applied for a patent registration, a process that went on for some years.
About 20 years after the patent was awarded, a similar system appeared in the United States, but without the internal device mentioned above.
