		This photo of Gaping Gill main chamber was taken arround 1999 during one of the winch meets with my old Canon AE1-P, mounted on a tripod. Lighting was by several flashes from a flash gun plus the obvious ambient. Exposure etc from memory was probably 20-30 seconds at f2.8 ISO 400 with a Canon 28mm lens. This was the best effort of the day and the print has been scanned in with an oldish scanner some years ago. Wish I could find the negative, but it would probably be much easier and far more to go back...
