The Dumpling

Posted on by

Just to the south of Loch Lomond beside the village of Gatocharn lies Duncryne Hill – a positively cute protrusion consisting of sandstone and conglomerate from the Emsian era early in the Devonian Period, affectionately known as The Dumpling.

Having discovered it on Google Earth, thinking it might afford good views over Loch Lomond and the Highlands to the north, I visited it this past weekend.

I wasn’t disappointed.

Approaching The Dumpling

Some artwork – looking at Loch Lomond from the top of Duncryne Hill:

The Highland Boundary Fault runs from Arran to the south-west, cutting through Loch Lomond between Arden (west) to Balmaha (east), forming a clear escarpment along the side of Conic Hill.

 

The Highland Boundary Fault runs right through the middle of this photo – through Loch Lomond around Balmaha, causing the rising mountains to the right of the scene.

The clouds were fairly zipping along, obscuring and bathing the landscape in crepuscular rays, so I had to make a short timelapse video of the vista:

With such light and rain-clouds passing by, on returning to the top of the hill I was greeted by a dramatic full-on rainbow with complete primary and secondary bows and supernumaries glowing in super-saturated vibrant arcs over the trig-point.

And just to finish the day’s expedition, there was some beautiful early golden-hour evening sunlight back-lighting a group of trees outside Drymen.

A Day In Clouds

That was 2017-06-20, that was. A beautiful blue sky with white fluffy wispy cirrus cloud catching the setting sun…

…followed by a noctilucent cloud display around 1am:

NLCs are the highest-flying clouds, occurring at altitudes up to 80km where the next highest type (cumulonimbus) only reaches 12km and most are lower still. Most typically they resemble a fine silver filigree of ice-cold pale blue, although more complex forms have been seen. First maybe-seen in 1885, they only really came to prominence since the 1980s, as a canary for changes in the upper atmosphere linked to climate change.

As I stood and watched the display, a patch of silver mist formed over Strathearn and made its way west along the A85 toward Crieff, so I made a little timelapse video – 17 minutes’ data compressed into 1:

Noctilucent Clouds (NLCs) 2017-06-15

It’s just a week off being the longest day, and it seems never to really get dark at night around here at the moment. Still. While that precludes shooting the aurora, instead it’s noctilucent cloud (NLC) season – just started in the past couple of days so I was very pleased to capture these last night / this morning around 1am.

Apart from being a canary for global warming, NLCs are a beautiful phenomenon, glowing cold bluey-white typically filament threads lighting up the sky. Or, if you leave the camera thinking for 2 minutes they blur nicely with the more mundane clouds:

A total 2 minutes of exposure to see what the NLCs and ordinary clouds would get up to over that kind of timescale.

And I made a short timelapse – 6 minutes compressed into an 11-second video:

Portknockie

Posted on by

Continuing the mega road-trip drive from a day in April: having taken in Dunnottar castle I proceeded up to Portknockie on the north Moray coast. A well-known location with lots of scope to explore, sitting on a transition between red sandstone conglomerate and quartzite underlying rock.

 

Bow-Fiddle rock itself is situated just beyond the mouth of a cove with interesting caves to the north side:

We’re heading down to that strip of a pebble beach…

There’s a classic composition to be had by heading down to the boulders just beyond the pebble beach, plonking one’s tripod on the rock and adding enough ND filters to make a long exposure. With the right light and the wind kicking-up choppy waves, it can make for pleasantly dramatic arty photos. And despite being a sunny day, having to lie down on the hard rock to keep my shadow out of the shot, it definitely didn’t disappoint…

Technical details:

Pentax K-1; Samyang 24mm f/1.4 lens at f/11; Nisi ND1000 (equivalent to a Big Stopper) and circular polariser filters; ISO 100; 30s exposure using pixel-shift for a total of 2 minutes’ exposure at high resolution.
