created an equivalent

I simply function when I take a picture. I do not photograph with preconceived notions about life. I put down what I have to say when I must. That is my role, according to my own way of feeling it. Perhaps it is beyond feeling.

What is of greatest importance is to hold a moment, to record something so completely that those who see it will relive an equivalent* of what has been expressed.

[…]

I want solely to make an image of what I have seen, not of what it means to me. It is only after I have created an equivalent of what moved me that I can begin to think about its significance.

Shapes, as such, do not interest me unless they happen to be an outer equivalent of something already taking form within me. To many, shapes matter in their own right. As I see it, this has nothing to do with photography, but with the merely literary or pictorial.

—Alfred Stieglitz, quoted by Dorothy Norman in Alfred Stieglitz (The History of Photography Series, Aperture, Inc., 1976).

*After 1922 Stieglitz used the term "Equivalents" to describe his photographic series of clouds.
