Who was the Hockney - Falco thesis named after ?
The Hockney – Falco thesis is a controversial theory of art history , advanced by artist David Hockney and physicist Charles M. Falco , suggesting that advances in realism and accuracy in the history of Western art since the Renaissance were primarily the result of optical aids such as the camera obscura , camera lucida , and curved mirrors , rather than solely due the development of artistic technique and skill .
