You can also see sometimes that the best pictures are the ones where you didn't try so hard, where you were just enjoying the process - and you didn't even know why you were making the picture. It felt right. If someone asked, 'Why are you making this picture?' you probably couldn't describe it very well - and that's why it needs to be a photograph.

It had rained on some vivid green ferns in Maine and it was quite beautiful. I was moving the camera slightly and studying the ground glass. Looking at those 20 square inches, trying to find out just what were the right elements to include.

So to me it's very similar in terms of trying to distill within the image, those elements that are gonna form, hopefully, a compelling visual statement.

I find the surface of a photograph a thing of beauty in and of itself, and it is this surface that makes a photograph unique relative to other two-dimensional media.

It was an experience that was exceptional. People frequently ask what it was like and it truly was inspiring. Sometimes during his lifetime, people would try and put him on a pedestal and that's not where he wanted to be, but he was really a great individual.

Whatever it takes to get the image to reach that level is what that photographer needs to do. And for me, I just have such a love of the tactile and sensuous quality of a black and white silver gelatin print.

I took a workshop from him a few months after that. That experience changed my whole approach to photography. At that workshop in Yosemite in 1973 I decided I wanted to try and see if I could pursue this for myself, and I'm still trying.
