Valid photography, like humor, seems to be too serious a matter to talk about seriously. If, in a note, it can’t be defined weightily, what it is not can be stated with the utmost finality. It is not the image of Secretary Dulles descending from a plane It is not cute cats, nor touchdowns, nor nudes; motherhood; arrangements of manufacturers’ products. Under no circumstances is it anything ever anywhere near a beach. In short it is not a lie - a cliché - somebody else’s idea. It is prime vision combined with quality of feeling, no less. - Walker Evans
