Hatch on the Soviet Submarine at the Maritime Museum of San Diego.
Easily one of the most challenging places to photograph because of the cramped conditions and light.
Five hatches like the one in the image need to be passed through when touring the submarine.
A real challenge with camera and camera bag.
