Dr Catherine M. Weir is a visual artist and researcher, working primarily with photography, data, and code. Her practice-based research is centred on an exploration of the relationships between her chosen media; and the implications of their increasing convergence for contemporary digital photographic practice and theory. Central to this inquiry is an understanding that today’s digital photographs – particularly those viewed on screen – are no longer straightforward remediations of chemical-based photography, but the output of active computational processes: networked, programmable hybrids of images and data.

Catherine's PhD research – which was supported by a full studentship from the Arts and Humanities Research Council – examined how the semiotic concept of indexicality developed by Charles Sanders Peirce can be understood in the context of an expanded digital photographic practice; with a focus on artworks combining digital photographs with real-time and recorded data in custom software programs.
