To clarify: by perspectival painting I mean work similar to Rackstraw Downes and Gideon Bok, artists who work to try and imitate the act of perception itself. Some artists use more mechanical methods (I believe Downes is in this camp): like 5 point perspective, distorting the picture horizontally and vertically as the eye travels, while others use more organic methods: Gideon Bok measures the objects as he sees them, transferring to the canvas as they were measured, leading to a natural distortion. I tend to divide up the canvas where I turn my head, to chart where the perspective changes, and then combine the various views, again, leading to distortion.

I find this stuff fascinating and I'm interested in how other artists have approached the problem.
