Some may find this kinda tedious or irelevant.

I thought it pretty interesting, and similar in many ways to the stories and theories of older "damascus" steel swords or katanas. And the debates over "custom" and "handmade". Or a recent BFC thread where some folks thought it unbearably presumptuous that Cliff Stamp review a knife made by Ed Fowler, provided him by a third party who owns the knife, without asking "permission" from Fowler.

From Intro...

This two-day conference will present a public discussion of a startling new theory being advanced by world renowned artist David Hockney, working in collaboration with University of Arizona physicist Charles Falco, to the effect that, as far back as the 1420s, Master Painters in the High Tradition were deploying optical devices to render lifelike images of people and their surroundings. The conference will bring together Hockney, Falco, and their principal supporters and skeptics among art and science historians, critics, scientists and painters for the first full public airing of their views.

Most art historians believe the majority of European painters since the Italian Renaissance deployed elaborate systems of mathematical perspective to achieve their effects. Over the past several years, however, Hockney and Falco have been arguing that, on the contrary, most artists in the High Tradition, going all the way back to Bruges in the 1420s, were deploying a variety of optical devices (ranging from concave mirrors through lenses and cameras obscura and lucida). In effect they suggest that painters (from Van Eyck through Caravaggio, Lotto, Velazquez, Vermeer, Chardin, Ingres, etc.) were using precursors of photographic cameras for centuries before the invention of chemical fixatives in 1839; and that it was only with the spread of such chemical fixatives that European painters, suddenly disenchanted with the "optical look," began to undertake the critique of photography implicit in impressionism, expressionism and cubism and the rest of the modernist tradition....


Some fascimilies of the papers on presented by either side are presented, as well as some debate that continued after the meeting. "Sixty Minutes" ran (presumably re-ran) a fairly superfluous piece on the topic last night, and I decided to look a little deeper on the 'net. The linked articles at artkrush.com don't work for me--here's working links:

Holy moly. That's interesting. But, why am I reading page after page about *art* when I've never been interested in it before? ;)
 
interesting stuff.

on the topic of mediaeval art & optics, here's one of my favourite paintings, 'The Ambassadors' by Hans Holbein the Younger (1533):

Unfortunately, this is not as controversial a topic as it may seem. This was the subject of a seminar I helped with back in 1998 and we've known for a long time that optics have played a role in painting and even architecture since before the 15th C.

A browsing through any respectable collection of Trompe L'Oeil works show optics playing a part in paintings, sculpture and even architecture well back into Ancient Greece.

Perhaps it is because I am not a dyed-in-the-wool Art History Prof. (rather, I seek out stuff like this) that it is not new to me. Is it true, though, that most older Professors are still teaching the "mechanical roots" of perspective, despite the large amount of evidence pointing to optics, both inside and outside of Italy.

It is not unusual to find Pre-16th Cent. paintings where one of the subjects is holding a mirror, on which you would see a reflection of the artist, or his studio, or people looking over the artist's shoulder. Things that can only be done by studying optics.



Anyway, I got a big kick out of that thread by Cliff. You gotta hand it to him for somehow causing quite a stir without doing much pot stirring himself. Such devotion to the cause...:D

Pen is correct. I found it pretty funny how both sides seemed to want to take things to the extreme.

To me linear optics and mechanical perspective are two sides of the same coin. But some of the issues of color rendition, shading and shadow brought up by both sides I hadn't seen before.

Beo, that's an often cited example of an anamorphic image. (Actually a pretty simple one) One could certainly imagine producing it (at least the outline) by following a projection on on a tilted canvas if the problem of narrow depth of focus is solved somehow.

There are a lot of examples where the image is properly rendered only upon reflection onto a cylindrical mirror:

Somewhere in my entropy-sink of a residence I've got a nice book with a bunch of examples that came with a sheet of silvered mylar to roll up and view the images.

A web-search should bring up a bunch of stuff.

Zal, never know what's going to show up here in the Cantina--Lot's of us here have a "non-conventional perspective" on things.
 
I once saw a Still Life that had clearly been done with the aid of a camera obscura . The stuff in the middle of the table was in focus but the the stuff in front and behind was out of focus.
