Photography is a medium of formidable contradictions. It is both ridiculously easy and almost impossibly difficult. It is easy because its technical rudiments can readily be mastered by anyonwith a few simple instructions. It is difficult because, while while the artist working in any other medium begins with a blank surface and gradually brings his conception into being, the photographer is the only imagemaker who begins with the picture completed. His emotions, his knowledge, and his native talent are brought into focus and fixed beyond recall the moment the shutter of his camera has closed.

I knew, of course, that trees and plants had roots, stems, bark, branches and foliage that reached up toward the light. But I was coming to realize that the real magician was light itself.

Every photograph is a fake from start to finish.

Some day there may be... machinery that needs but to be wound up and sent roaming o'er hill and dale, through fields and meadows, by babbling brooks and shady woods - in short, a machine that will discriminately select its subject and, by means of a skillful arrangement of springs and screws, compose its motif, expose the plate, develop, print, and even mount and frame the result of its excursion, so that there will be nothing for us to do but to send it to the Royal Photographic Society's exhibition and gratefully to receive the 'Royal Medal'.

The precision of hisskill places his work beyond the tentative and the experimental stage. He is continually searching and exploring both himself and his surroundings. and in this exploration of the realm of places, people and things, contrasts and relationships, Callahan is no respecter of conventional technical formula or code. His delicate sense of pattern is an integral part of his photography and not a thing by itself.

The use of the term art medium is, to say the least, misleading, for it is the artist that creates a work of art not the medium. It is the artist in photography that gives form to content by a distillation of ideas, thought, experience, insight and understanding.

There is only one optimist. He has been here since man has been on this earth, and that is man himself. If we hadn't had such a magnificent optimism to carry us through all these things, we wouldn't be here. We have survived it on our optimism.
