240 Polaroids were taken from the same position in the South Wing corridor of the hospital, from 5.45 am on 15th August to 5.45 am on 16th August 1996. (Out-of-date Polaroid film donated by KJP, now WEX Photo Video)
The shots were taken at 5 minute intervals, the camera was directed at people's feet as they walked past. Automatic functions on the camera were switched off so that there was no adjustment to movement or lack of light. It could be said that the camera was in a state of unconsciousness while the pictures were being taken, creating blurred and fragmented images.
Each image was displayed on the wall behind the camera recording the exact time at which it was taken.
The work was purchased by the Special Trustees of St Thomas' Hospital, and sited in the Sleep Research Centre.
