Using photographic images containing two persons, this study investigated the effects of lens focal length (F) on the perception of absolute distances to a person (A_p) and the relative distance between two persons (R_p). The absolute size of every person changed in proportion to F and in inverse proportion to actual distances, while the relative sizes of two persons did not change by F when the actual distances were the same. In the experiment, the participants estimated either A_p or R_p in each condition of different actual distances with different F. The results indicated that A_p was strongly affected by F, while R_p was scarcely influenced by F. These findings suggested that a powerful determinant of A_p was absolute size; however, a powerful determinant of R_p was relative size. Therefore, there might be a difference in the manner of processing information for the perception of absolute distances and relative distances in photographic images.
