Self Portrait looks for an approach to a specific relationship between the duration of a work and material conditions in the projection as did William Raban in the film-performance Take Measure. The main difference is that Raban’s work was made when cinematic media had distinct physical properties linking medium directly to image - this self portrait recognizes that there is no such simple materiality for cinema following the emergence of digital processes. Instead the work takes a conceptual base – the speed of light and the time taken for light to travel from the sun to illuminate objects on earth –thus the duration of 8 minutes 20 seconds.
