No double exposure, all done in one shot in the wheel barrow that we were cleaning our tools in. I accidentally left the spoon, which I was using to strike the mortar joints, in the wheel barrow and liked the way it looked the next morning. So at the end of the day I set up the shot with the spoon and wheel barrow positioned for the morning sun. The next day it turned out that the spoon was actually pretty hard to see so I gently moved away they scum that was floating on the surface of the water. Had fun, as it is usual for me to set up shots like this. Roger
