Liminality in the transformation of light during the process of photography (original) (raw)

Abstract

Abstract In this article, the concept of liminality is examined as it relates to the photographic process. It is examined how, at the time of exposure, light enters the darkened space of the camera through the aperture, and is then inverted and transformed to create an image on the light-sensitive medium inside the camera, using either film or digital sensors. Photographic images represent objects and data in front of the camera at the time of exposure. The discussion in this article, however, is focused on the transformation of such visual data captured in the light that emanates from the objects in the ambit of the aperture of the camera at the time of exposure. The contention is that since the captured light is transformed during the photographic process, an indexical character (that is, a one-to-one reference of the moment captured) cannot be ascribed to the photographic image representing the captured moment. To explain the argument, this process of transformation is related to the concept of liminality and how it affects the indexical nature of the photographic image, with specific reference to the photographic imagery of Michael Wesely and Jurek Wajdowicz.
