I am looking at photographing a wreck that lies in 167 fow. Thats the outer limits for my old Nikonos II. The dive plan is to spend the precious bottom time cruising the deck of an old schooner at 150 fow and snap pictures as I go. Any special precautions camerawise? I've had her down 125 previously with normal prep and no problems.
