There are some attempts to examine the mechanism of aesthetic quality assessment in visual images. To probe into the cause of aesthetic quality in natural scene, we focused on differences in the aesthetic quality between photographs and paintings of the natural scene. Using 23-dimensional verbal assessment of 15 landscape photographs and 15 paintings, we observed two important differences between them. First, subjective aesthetic quality from paintings often significantly changed after several months, while that of photographs was more stable comparing to paintings. Second, estimating aesthetic assessments by other people were more accurate in photographs than in paintings. The differences were partially explained by difference in color statistics between photographs and paintings, suggesting an involvement of a low-level sensory information processing. Our results suggest that judging aesthetic quality of landscape photographs was mainly explained by low-level mechanisms, while both low- and high-level information processing are necessary for paintings.
