English photographer whose studies of cathedrals in England and France are considered among the world's finest architectural photographs.

Little is known of Evans's early life. He first attracted attention as a London bookseller who accompanied his transactions with informative and stimulating conversation and who championed the work of two of his steady customers, the dramatist George Bernard Shaw (Shaw, George Bernard) and the artist Aubrey Beardsley (Beardsley, Aubrey).

A man of strong opinions on many subjects, Evans was constantly involved in controversy. His most impassioned beliefs involved what he considered to be the proper practice of photography. A purist, he believed in never altering a photographic image after exposing the film. His goal was to create an aesthetically and spiritually satisfying image, utilizing the play of light and shadow on static architectural structures. He did not try to capture spontaneous moments. His advice was largely ignored by younger photographers, and he spent the last years of his life virtually forgotten, privately publishing limited editions of platinotype editions of his collection of drawings by artists such as Beardsley.
