Some years ago I made my photo Raw from the same location, looking down the gorge formed by the river at the lower bridge at the Falls of Bruar. Previously, I used a large-format view-camera and Velvia film, and made an 8-second exposure in the "blue hour" after the sun had set.
On this occasion, I used a Lumix GH2 mid-afternoon: with enough filtration, several long exposures blended together to give much the same effect. The colours were adjusted in post-processing to try to loosely approximate film.
Located beyond the east end of the Loch Tay faultline, geological forces have thrust the rocks up with their strata revealed as the river eroded its way down. The prevailing rock is psammite, a semi-metamorphosed variant of sandstone.
