Persuasion Through Visual Metaphors:
an Analysis of Non-photographic Resources in Environmental Documentaries
Abstract
This paper aims to discuss the status of a specific type of images (non-photographic) as a persuasive tool in documentary films, specifically through its ability to build visual metaphors. Moreover, we seek to understand the construction of senses in these elements and their interdiscursive/intericonic connection to what we call an anti-industrial agriculture discursive formation (DF). Our empirical object of analysis are documentary films that explore the issue of industrial agriculture from an environmental perspective. Through our analysis, we show how non-photographical elements can expand the possibilities of representation and construction of meaning for both documentary film and environmental discourse. Our paper also pointed out that some of these visual and multimodal metaphors were employed to overcome the difficulty of representing invisible environmental problems.
