• The so-called panoramic photograph familiar to amateurs is a pseudo-panoramic picture because it is only more elongated than a normal-shaped photograph. Nevertheless, the photograph gives the impression of a wide view of the scene. If then, the panoramic impression increases with an increment in the horizontal to vertical aspect ratio and the size of the photograph, does the perceived lateral distance also increase in a similar manner? The present study examined the relationship between the panoramic impression and the perception of lateral expansion in photographs. In the experiment, 18 students evaluated the impression of a panoramic view in 45 photographs which varied in both aspect ratio and size. Another 14 students were asked to estimate the apparent lateral distance between two corn-shaped objects in each of the same photographs. The results showed that the panoramic impression increased significantly as either the aspect ratio or size increased. But the perceived distances were not influenced by the aspect ratio, and the apparent lateral distance decreased as the size of the photograph increased. These findings suggest that the perception of lateral expansion and the related panoramic impression might differ in their qualities.
