I prepared 7 images (like our seven days of the week) taken in 3 operating theatres of southern Italy. The shots were made with a large-format camera, attached to a tripod, exactly 5 minutes after the end of surgery and the exit of the patient, and 10 minutes before the nurses put the room in order for the next intervention. Therefore, in that time frame, there was opportunity for one shot only. It all started at 08:08 on March 21 to finish at 09:00 on 27 March 2009. I had also been waiting for interventions up to 8 hours long. - Pino Musi.
