the lifeboat is housed in a bold modern building together with an exhibition. This is taken through the glass at 1st floor level and shows the darker parts of the boat and within the museum; where there is no darkness in the field of view, you see the reflection of the street behind. Where there windows beyond, you see through them; all quite simple really.(for more complicated stuff look at John Hamers work http://www.pbase.com/johnh57/paris_ll)

However it is the jumble I like and momentary illusion that the boat is on a canal going towards the High Street! NB it is a single straight image with minimal PP
