Dürer wasn't just drawing, but analyzing perspective to better understand how it works. You no doubt have noticed that in some of the Dürer examples, the eye is positioned well above the center of the grid, giving the same effect as dropping the front on a view camera.
Do you mean like a perspective with 3 vanishing points, one of the most difficult to get right?
The intersector is a great tool for understanding how perspective works. When I taught the view camera I had the students make pinholes and an intersector which they attached to the front standard of the camera, and a stick on the rear standard to locate the eye.
What is the "intersector" and stick you talk about. Do you know a website that shows some image of this device. :confused: I do understand the rest of the explanation about the different bellows lengths, and the influence on the relationship between subject and background, but I am not familiar with the "intersector" as such...
These days, some very interesting work is being done using perspective. Gillian Brown has been painting from photographs right on the location where the original photographs were made: http://www.gillianbrown.com/JillStairs-1.htm. These works must be viewed from a particular point to make any sense at all.
Holy cow! Talking about drawing perspective... Thanks for that link. However, I guess the trick here is to project the image using a slide or digital projector, and than draw the outlines on the 3D surface... pretty much what is described for Caravaggio, just that he didn't use a 3D canvas... how else would you get this ever right? Even so, there is a lot of skill involved, because almost everything will be "stretched" out, making it difficult to judge what you do... probably lot's of walking around back to the projection / viewpoint to check if it's going right.
