Social Semiotics is an approach to visual communication that explores the understanding of how people communicate through various methods in differing social situations. It is an explanation how concepts, objects and figures interact in purposeful ways in order to create intended or implied meanings. The interaction between the image and the viewer is also seen as important; cultural and societal importances and normalities are often played upon within the images to chance or enhance the meanings of visual elements in order to transfer a potential meaning (or set of meanings) towards the intended audience.
Visual Social Semiotics reveals things that are not always evident at first glance in an image (Jewitt and Oyama, 2004). It uses a particular set of rules in order to decode and image, such as whether an image is narrative or conceptual, the interactive meaning, its compositional makeup and point of view. Cultural normalities and stereotypes are also utilised in the deconstructing of an image, as it is these signs and symbols that allow immediate understanding of any potential or insisted meanings.
