Hockney–Falco thesis - WikiVisually

Art historians and others have criticized Hockney's argument onthe grounds that the use of optical aids, though well-establishedin individual cases, has little value for explaining the overalldevelopment of Western art, and that historical records andpaintings and photographs of art studios (sans optical devices), aswell as present-day realist artists, demonstrate that high levelsof realism are possible without optical aids. TheHockney–Falco theory, however, never seeks to explain the "overalldevelopment of Western art," but merely some of thetechniques used in some parts of a painting or insome parts of the painters process, and admits that thesetechniques alone do not account for the final quality of apainting.

At a scientific conference in February 2007, Falco furtherargued that the Arabic physicist 's(965–1040) work on , inhis , may have influenced the use of optical aids byRenaissance artists. Falco said that his and Hockney's examples ofRenaissance art "demonstrate a continuum in the use of optics byartists from c. 1430, arguably initiated as a result of Ibnal-Haytham's influence, until today."

From there, Hockney began looking for signs of theuse of optical aids in earlier paintings, creating what he calledthe Great Wall in his studio by organizing images of greatrealistic art by time period.

In addition to incredulity on the part of art historians andcritics of modern art, some of the harshest criticism of theHockney–Falco thesis came from another expert in optics, imageprocessing and pattern recognition, David G. Stork. Stork analyzedthe images used by Falco and Hockney, and came to the conclusionthat they do not demonstrate the kinds of opticaldistortion that curved mirrors or converging lenses wouldcause. Falcohas claimed that Stork's published criticisms have relied onfabricated data and misrepresentations of Hockney and Falco'stheory. Storkhas rebutted this claim.

Critics of the Hockney–Falco theory claim that the quality ofmirrors and optical glass for the period before 1550 and a lack oftextual evidence (excluding paintings themselves as "documentaryevidence") of their use for image projection during this periodcasts doubt on the theory. However, the historians were moresanguine about the possible relevance of the thesis between 1550and the invention of the telescope, and cautiously supportive afterthat period, when there clearly was interest and capacity toproject realistic images; 17th century painters such as and used opticaldevices in variety of ways, though not the ways postulated byHockney.
