What a landscape photographer traditionally tries to do is show what is past, present, and future at once. You want ghosts and the daily news and prophecy... It’s presumptuous and ridiculous. You fail all the time.

This is the gift of the landscape photograph, that the heart finds a place to stand. Walker Evans
[Photographer, b. 1903, St. Louis, Missouri, d. 1975, New Haven, Connecticut.]
...nature photographs downright bore me for some reason or other. I think: “Oh, yes. Look at that sand dune. What of it?” Lucy Lippard
[Critic and writer, b. 1936, New York, lives in Galisteo, New Mexico.]
Men have dominated the field of landscape photography just as they have dominated the land itself. Thus “shooting” a “virgin” landscape has been man’s work—hunting, not gardening. Jeff Wall
[Photographer, b. 1946, Vancouver, Canada, lives in Vancouver.]
In making a landscape we must withdraw a certain distance—far enough to detach ourselves from the immediate presence of other people (figures), but not so far as to lose the ability to distinguish them as agents in a social space. Or, more accurately, it is just at the point where we begin to lose sight of the figures as agents, that the landscape crystallizes as a genre. R. Crumb
[Cartoonist, b. 1943, Philadelphia, Pennsylvania, lives in Sauve, France.]
They were just snapshots, nothing special, nothing particularly artistic. They were used for utility purposes.(On photographs of mundane streetscapes he had “Stanley Something-or-other” take in Sacramento in 1988 to serve as backgrounds to his cartoons. “People don’t draw it, all this crap, people don’t focus attention on it because it’s ugly, it’s bleak, it’s depressing... But, this is the world we live in; I wanted my work to reflect that, the background reality of urban life.”)

... I’m interested in using the iconography of nature and the American landscape as surrogates or metaphors for psychological anxiety, fear or desire. Vik Muniz
[Artist, b. 1961, Sao Paulo, Brazil, lives in New York.]
My first reaction to finding Robert Smithson’s Spiral Jetty in a book was, “Wow, what a great photograph!” I could not believe that someone had gone to so much trouble just to end up with a picture.
