Identification of visual dimensions in photographs using multidimensional scaling techniques

An examination of underlying visual dimensions commonly perceived in photographs was conducted using multidimensional scaling techniques. Fifteen male and female university graduate students individually examined 34 photographs chosen to represent a broad range of visual topics. Similarity judgments between photographs were used for multidimensional scaling, while subject interview data were used to describe meaningful visual concepts. Results indicate that pictures were grouped in clusters along three observable dimensions. Life, nature, and culture emerged as the dimensions of primary importance to viewers. This suggests the existence of universal meaning systems in visuals for communicating denotative and connotative meaning and presents experimental variables for future hypothesis testing.
