With a couple of hours to spare on Sunday afternoon, I revisited the Falls of Bruar. Even  on a grotty wet day there were plenty of opportunities, around the lower bridge.

It’s at least the 8th time I’ve been there – but the geology is impressive as always with the natural arch formed by the river eroding the local rock (mostly psammite, as with much of the Highlands).

Some experiments with Live Composite mode on the Olympus Pen-F, as well as the usual (for me) high-resolution mode; everything taken using a circular polariser and ND4 filter for longer exposure times. Having made initial RAW conversions using RawTherapee, everything has been passed through LuminanceHDR to even-out the white-balance and tonemap for better image tone. (In cases where there’s only a small area of light in the frame, such as these flowing waterfalls, the Pattanaik algorithm can give interesting high-contrast results – set the gamma to about 0.3 and the frame turns mostly black with just the highlights remaining.)
