I could almost believe that the Ricoh GRiii had read my recent blog post on spontaneity and imperfection as at the end of a walkabout in Plymouth it started shooting continuously and hence doubling and tripling the frames into these superimposed exposures. Since they were all the monuments on Plymouth Hoe of historic naval and air force commemorations, there is a certain rightness to their other worldliness:-

Drake and Armada monuments, built in 1888 to celebrate 300 years since the defeat of the Armada
Royal Air Force & Allied Air Forces monument, dedicated to all the men and women who served, both in the air and on the ground, during World War Two
The Plymouth Naval Memorial commemorates 7,251 sailors of the First World War and 15,933 of the Second World War.

And in future if I want to do deliberate double exposures, there is a link on my camera tutorials page
