ABSTRACT
Most of us are surrounded by photographs; they perform a variety of roles and functions within and around our lives. From advertising images and news photographs to artworks on gallery walls or within digital collections, photographic images have become a ubiquitous presence in contemporary culture. Its applications range from everyday usage, for example, in the ‘selfie’ taken on a mobile phone to more distinct, specialized applications such as medical photography to aid scientific study. For some of us, photographs may be among our most treasured possessions.
