Hattersley wrote colourfully on his theories on the principles and procedures of photographic criticism in a lengthy article in
Aperture magazine which it reprinted from
Popular Photography, and his criticism appeared in numbers of publications, including in the
American Society of Magazine Photographers magazine
Infinity for which he was the managing editor. Like his contemporary Minor White, Hattersley regarded photography as having a spiritual dimension; after pages of uncredited, uncaptioned photographs in a 1972
Aperture issue appears his statement; He wrote about printing in a darkroom as an opportunity for meditation, a quiet time that can be therapeutic, and further, that "the upside-down image on the ground glass tends to engage the right side of the brain, the artist's side, more than the technical, left side of the brain." White, in his
Aperture editorial in 1964 praised his approach; Hattersley's book,
Discover Yourself Through Photography enlarged on his ideas. Across the Atlantic however, British commentators regarded such sentiments about the medium with caution. ==Photographer==
