ambiguity revisited is concerned with the manner in which pictures communicate with the spectator. Its focus lies in those fluid, indeterminate spaces where our reading of images, in art and photography, exercises and draws upon our imagination, memory, and experience. Sir William Empson’s seminal (1930) text: Seven Types of Ambiguity is used as a springboard to discussion, towards a fresh way of exploring ambiguity beyond English literature, and in a broader framework to that contained in John Berger’s (1989) Another Way of Telling.The use of ambiguity in art and photography, as in literature, is both a conscious and an unconscious act; and ambiguity influences the way in which we respond to work, from Leonardo da Vinci’s portraits to the photographer William Eggleston’s engaging and idiosyncratic reflections on America’s Deep South. This ambiguity is a force for good, or at least one to be reckoned with, due to its participatory nature in actively engaging with, or masking itself from, the viewer.Ambiguity is infrequently discussed but is highly relevant as an expressive device. It holds a position at the core of communication within the visual arts. As society becomes influenced increasingly by communications delivered in a visual form, so we, the consumers, require tools, more than ever, to engage with the work.
