This study investigated the combined effects of the quality and clarity of a photographic illustration as factors influencing a viewer's recall of the content of the photography. The stylistic elements of lighting, image quality, degree of detail, image sharpness and perspective were manipulated in order to control the overall quality and clarity of the image. Photographs designated high signal noise ratio (S/N) had high overall quality and clarity. Photographs designated low S/N had minimum acceptable quality and clarity. Eighteen high and low S/N photographs of agricultural produce were shown randomly to 204 first‐year communication students in four groups. The subjects were also identified according to their preferred information processing modality— visual, aural or visual and aural. Five days after the presentation of the photographs, the subjects were asked to list the content of as many photographs as they could remember.
