This is the original water-wheel at Mapledurham.
Now, dear Am3'ers, you know I like water power as an alternative power source, so, obviously I wanted to know how much power it produced at its height of refinement and maintenance. The staff at Mapledurham didn't know, and just kept talking about how many bags of flour it could mill.
So, based on some "Back of fag packet" hydrodynamic calculations I reckon it could produce around 10-15Kw. This number becomes important tomorrow....
This ended up being a desperately irritating shot to take-either the sky and the wall were completely bleached out, or the right hand part of the wheel was completely black I kept looking at the wheel, take a shot, "Chimp" on the back of the camera, not see on the back what I saw in the flesh, up the exposure, down the exposure, not be happy. So this ended up being a 3 shot handheld sequence that I manually masked together(i.e. no automated HDR, but instead chose which bits of over, under and normal exposure made it through to the final image)
