Water close-ups

A small series of closeup studies in flowing water, taken on a stroll around the Falls of Bruar.

I’ve admired the striation lines  in the psammite riverbed below the lower bridge at the Falls many times – yet every visit they’re still fascinating every time.

Noctilucent Clouds, Perth, 20150623

A classic location for long-exposure night-time photography: standing on the bridge over the M90 at Rhynd, with the road snaking away into the distance… and a clear display of noctilucent clouds above Kinnoull Hill.

From wikipedia:

Night clouds or noctilucent clouds are tenuous cloud-like phenomena that are the “ragged edge” of a much brighter and pervasive polar cloud layer called polar mesospheric clouds in the upper atmosphere, visible in a deep twilight. They are made of crystals of water ice. Noctilucent roughly means night shining in Latin. They are most commonly observed in the summer months at latitudes between 50° and 70° north and south of the equator. They can be observed only when the Sun is below the horizon.

They are the highest clouds in Earth’s atmosphere, located in the mesosphere at altitudes of around 76 to 85 kilometres (47 to 53 mi). They are normally too faint to be seen, and are visible only when illuminated by sunlight from below the horizon while the lower layers of the atmosphere are in the Earth’s shadow. Noctilucent clouds are not fully understood and are a recently discovered meteorological phenomenon; there is no record of their observation before 1885.

Changeable Weather

A few photos from the start of January – experimenting with a road I’ve not often travelled, up from the A9 to approach from the south. It was a stunning morning – swathes of cloud-shadow flying across the landscape such that the mountains north of Comrie were alternately visible or obscured behind passing snow/hail clouds.

Glen Affric: Landscape

Two final landscape scenes to close this series. It was a long morning spent watching the sun rise, walking around the River Walk and along the side of Loch Affric past An Tudair, before returning to the River Walk a second time and clambering up the opposite hill to the memorial to capture the passing light on pine-covered mountains above the loch.

Glen Affric: Rockery

There’s an impressive outcrop of rocks (psammite and semi-pelite, looking rather like limestone) near the waterfalls in the River Affric. Some kindly soul had balanced these pebbles on a boulder on their way past previously.

Glen Affric: Mixed Thoughts

Sadly, it’s not all good news at the glen – a few years ago, the Forestry Commission installed two paths, one wending its way between the trees like a play-park and the other using non-native sandstone paving flags to enlarge the walk beside the river – in the process, cementing its way through the pine trees’ roots. I am not impressed.

The other two photos in this set are a bit strange by my standards, too: shooting directly into the sun with only a few seconds to capture a crepuscular ray, I extended my usual HDR bracketing from 1EV to 2 stops either side; it’s taken me the last 6 months and no fewer than 10 re-processing iterations to make the best I can of that scene and the results are necessarily unrealistic in order to capture detail in both foreground and sky. The scene is from the path along the south side of Loch Affric to Kintail, beside Loch Salach a’Ghiubhais (“dirty loch of the pines”) – I have no idea what they did to merit such a title, as it seems a pretty gorgeous place to me.

Glen Affric: Trees (4)

Lots of Scots Pine trees around Glen Affric.

Favourite Trees can be seen from near the carpark above the River Walk around the glen – these are the same pines that appear in Heather and Trees.

Gnarly struck me as a pleasant old character, enjoying the morning sun, on the way up the side of Coille na Feithe Buidhe to the memorial.

The trees is Pinus sylvestris are to be found along the south side of Loch Affric, on the path that ultimately brings you out in Kintail near Skye.

Sun behind clouds

Helios 58mm f/2 lens wide open but with a pinhole drilled in the lens-cap, giving an effective aperture of about f/30 (almost two stops narrower than the lens’s own aperture scale). This was just slow enough to allow a reasonable hand-held exposure of the sun behind iridescent clouds, although it still took a lot of care to retrieve detail in the highlights.

Perth close-ups: floral colour

The last in a short series of photos from a stroll around Perth.

These are all processed slightly differently from my usual workflow – instead of darktable, I used RawTherapee with a film emulation (allegedly Fuji Provia). As with the others in this series, all images were made on a Helios 58mm f/2 prime lens, pretty wide open.
