In a book on refraction, published in 1593, the eye and the camera obscura were compared by Porta. He also covered refraction, vision, the rainbow, prismatic colors (all subjects treated by the early experimenters in optics).

Porta had a great, though mixed, influence. Even in his own mind he did not seem able to decide whether the magic shadows should be used to deceive the public as effects of secret powers or whether they should be used for genuine entertainment and instruction.

Da Vinci told how the camera could be used; Porta tried it out for entertainment on a considerable scale but there still was need for penetrating attention from a scientist. That Kepler supplied.
