Photographs were classified under subject headings which were adapted as the collection grew and as new images were acquired. In 1948 the photographic holdings were described thus: "The collection is a continually growing collection which is intended to present in visual form examples from all fields of applied art and industrial design which are the concern of the Council."
Important components of DCA/30 are photographic material relating to the journal 'Design', from the first issue in 1949 until the 1980s, and photographic material relating to the Council's various award schemes from 1957 onwards.
