What the art historians had forgotten is that in Chinese, Japanese, Persian, and Indian art, they never painted shadows. Why did they paint shadows in European art? Shadows are because of optics. Optics need shadows and strong light. Strong light makes the deepest shadows. It took me a few years to realize fully that the art historians didn't grasp that. There are a lot of interesting new things, ideas, pictures.

West Yorkshire is quite dramatic and beautiful, the crags and things.

Shadows sometimes people don't see shadows. The Chinese of course never paint them in pictures, oriental art never deals with shadow. But I noticed these shadows and I knew it meant it was sunny.

I've always been interested in space in pictures. I think my going deaf increased my spatial sense, because I can't get the direction of sound. I feel that I see space very clearly, and that's because I can't hear it. So it's a compensatory thing.

I think the ambiguity of similarity and difference is very powerful. It's the same scene in different times of year read across the grid, and, of course, different locations reading vertically. But you can get confused and lost in the series. You force the mind, which is always comparing and contrasting, to stumble ... That ambiguity is very powerful. One is getting lost and refinding oneself.

I think the Enlightenment is leading us into a dark hole, really.

Photography hankers after the condition of the neutral observer. But there can be no such things as a neutral observer. For something to be seen, it must be looked at by somebody, and any true and real depiction must be an account of the experience of that looking.
