Falco will discuss the influence lenses have had, and continue to have, in the production, interpretation, and distribution of artistic images. Followed by a demonstration of a camera obscura.
Basically as I inderstand this. Charles Falco teamed up with David Hockney and they came up with a thesis that many paintings and art around the rennaissance period used Camera obscura's Camera lucida's and that lens signatures of the time created a type of distortion to paintings that echoed what the lenses reproduced at the time.
I will not be taping this event if I go but there is plenty listed about the collaborative thesis of Hockney and Falco on the internet.
