The image of a column of steam against the sky flickers from blur to clarity as the camera’s autofocus struggles to maintain a sharp image. As the camera’s uncertainty increases, a gradually building soundtrack changes volume in time with each twitch of the automatic focus.

A computer application has been made by the artist to measure the degree of blur in the original footage, and translate this into an increase in volume of sound. This gives audible form to subtle changes in the light levels in the video frame, producing a piece where the intrinsic shortcomings of the capture apparatus are highlighted in the work.
