Saw dappled sunlight through water... looked as if it were lights from an underwater city.

Nicely done.

I'm not qualified to critique the technical aspects of your video, but it was worth watching for the sample photos alone. Those were, IMO, some absolutely fantastic pictures.

Building Materials

Corrugated iron was patented in 1828 and used extensively in the traditional construction of roofs in Scotland, the French however...

Well right up until 1981, built vehicles from it...

This one has been recycled from 1964, to IMHO something far more useful than a panel van.

I believe there were some airplane fuselage sides made with corrugated metal in the 1920s or 30s.

The Citroën H-van is popular around the world as a mobile (sometimes static) coffee and snack buffet. I’m sure you know that the reason for corrugating sheet steel is that it makes light, thin sheet structurally stronger and reduces the resonance (“drumming”) effect from large areas of it.

The Fokker Tri-motor aircraft (built in the US also by Ford) used it for just those reasons. Apologies – I was thinking of the Junkers Ju52, which was constructed in aluminium, not steel.

Trust me this is not the case when it's on the roof with inclement Scottish weather... it's like being in a deafening biscuit tin.

Rikenon 50/2 is one very sharp lens (at f 5.6 is sharper than Pentax M/A 50/1.7).
