Morvern 5/4: The Road Back

And so we come to the last post in the series, a set of photos not entirely in Morvern but more on the way back up the shores of Loch Sunart and Loch Linnhe to the Corran Ferry, across and down to Loch Leven at Ballachulish.

There’s something wonderfully uplifting about rattling along these wee roads on beautiful sunny days, admiring the light.

Morvern 4/4: The Viewpoint

After the long drive, the walk in the woods, the angst of the cleared township, the second part of the walk resumes through the woodlands up hill to the viewpoint, looking out over Loch Doire nam Mart to the caves in craggy Beinn Uamh and beyond. On a sunny day with a few white clouds in a crystal-clear blue sky, it doesn’t get much nicer than this.

After a second walk through the woods around Aoineadh Mor, towards the top of the hill one comes across this beautiful view: conifer trees, Loch Doire nam Mart and more trees scattered on the slopes of craggy Beinn Uamh, all beneath a crystal clear blue sky.

Well, it does get a little better – Doglet had his dinner on the shores of the loch in amongst the rushes. Lucky chap.

Morvern 1/4: Approach

The West coast of Scotland – Lochaber, Argyll and further north – is well known for its amazing scenery. Earlier in the year I had a look around on Google Earth and thought the landscape looked pretty impressive opposite Mull around the Ardtornish area on the Morvern peninsula.

It certainly did not disappoint. Even having just driven 4 hours all around Fort William, across and round Loch Eil at great length (single-track road with passing places and a 60 limit), I had to stop to admire the crystal clear blue sky and lines of mountains receding into the distance:

There followed a short drive down to Loch Arienas, which was also just beautiful – blue water reflecting blue sky:

The Return of Serif

It feels funny to think that back in the early 1990s Serif was known for PagePlus, in the days when such things were known as desktop publishing or DTP applications.

Recently, however, they’ve produced Affinity Photo for Mac, Windows and iPad. After one or two folks recommended it, I thought it was time to add another trick to the photo-publishing workflow and have a play. After all, if nothing else, having an iPad would solve my doubts with colour-management issues on Linux, wouldn’t it?

So I’ve spent a few weeks driving around hunting scenery and taking photos of it and gradually evolving a few routines: photos are still shot on the Pentax K-1; processed (variously pixel-shift or HDR) using dcraw on Linux, where I also run them through darktable for a lot of toning work; the results are then copied to an ownCloud folder which synchronizes automagically with the iPad; a bit of juggling with share-to-Affinity and share-to-Photos and share-to-ownCloud later and the results are copied back to the workstation for final organization, checks and publication.

Within Affinity, my workflow is to import an image and ensure it’s converted to 16-bit P3 colour-space – this is a bit wider than sRGB and native to the iPad’s display. I then run the Develop module which tweaks exposure, brightness and contrast, clarity, detail, colour-balance (not so much), lens distortions, etc. After that, I use layers to remove sensor-dust and other undesirable feature. Top tip, use a new pixel layer for the in-painting tool set to “this layer and below”; then all the in-paintings can be toggled on and off to see the effect; also use a brightness+contrast adjustment layer above that while you work, so the corrections will be even less visible when the contrast is reduced back to normal. If the image requires it, I’ll add one or two fill layers for gradients – better to use an elliptical gradient that can be moved around the scene than a vignette that only applies in the corners. Finally, I merge all the layers to a visible sum-of-all-below pixel layer,on which I run the Tonemapping persona; ignoring all the standard presets (which are awful), I have a couple of my own that make black-and-white in low- and high-key targets, in which I can balance local versus global contrast. If I produce a black&white image, it probably arises from this layer directly; sometimes, dropping the post-tonemapped layer into the luminosity channel makes for a better colour image as well (subject to opacity tweaking).

So, some results. It produces colour:

It produces black and white:

One final thing: I used to hate the process of adding metadata – titles and descriptions, slogging through all my tags for the most pertinent ones, etc. Because the ownCloud layer is so slow and clunky, it makes more sense to be more selective, choose fewer photos to go through it; if I also add metadata at this stage, I can concentrate on processing each image with particular goals in mind, knowing that all future versions will be annotated correctly in advance. Freedom!

Trying something a little different

For years now, my photo-processing workflow has been 100% open-source. However, in the interests of greater portability – hack on photos whilst on the go – and partly gratuitously for the sake of variety, I recently acquired an iPad Pro 10.5″ and installed the Affinity Photo app.

As a user experience goes, it’s really quite pleasant. The best way to synchronise files around the LAN seems to be Seafile, which is open-source and available for Linux, iOS and android. My Linux-based workflow regularly produces 64-megapixel images, working on multiple intermediate TIFF files, 16-bit ProPhotoRGB-linear; somewhat surprisingly, seafile, the iPad and Affinity Photo seem able to handle files around 450MiB in size. There are a few small gotchas – I had to import a few ICC colour profiles by hand and as yet, there doesn’t seem to be a way to customise export options (so you have to select JPEG 99% sRGB lanczos yourself afresh every time); I’m sure these things will come in time however.

So here’s a shot from last Sunday afternoon. As I was heading out of Muthill I saw this characterful old tree in a field; on the return journey a few hours later, not only was it still there but the clouds were darker in the background and the golden sunlight caught the bare branches. A very quick bit of parking and even quicker sprint back to the optimum viewpoint and it looked stunning. So I processed it a little further, realising an intention for how it should look that was apparent from the start.

Just One Photo

Black Spout Waterfall, Pitlochry

Some days you only need to come away with one landscape image to justify an excursion.

On Saturday I set sail with Doglet and a friend and strolled through Black Spout Woods around Pitlochry, up to the viewpoint across the gorge where you can see the full height of the waterfall, and then round to the more accessible bit near the top of the falls, which still takes a fair amount of scrambling around on the river bank to get down to.

 

A nice stroll through the woods, a view across the gorge to the full height of the waterfall, some scrambling around on the banks to get down to this level (a small fraction of the total height down from the top) with friend and dog… A good way to spend an afternoon

Technicalities:

There are three conscious aspects to this shot:

Composition

I wanted to make the most of the 15-30mm lens, so with a bit of wiggling around at the scene I found a spot right in front of the cascades that would showcase the 16mm ultra-wide field of view with a strong foreground. Nothing clipped; there’s negligible cropping except for lens-correction. There’s something in each pair of corners: the strong diagonal line of the dead tree-trunk in the foreground is echoed by the three distant trees in the far top-left; the negative space of the burnt-out sky has an echo in the expanse of run-off water in the bottom; treated as three stripes, there’s a balance between the height of the frame given to the run-off, to the bright white cascades, and to the woods+sky at the top.

Sensor controls

I made 10 source images on the Pentax K-1, varying the exposure as follows:

f/13.0 1/50s; f/14.0 1/8s;
f/16.0 0.4s; f/16.0 0.5s
f/16.0 0.5s; f/16.0 0.8s
f/16.0 1/4s; f/16.0 1/8s
f/16.0 1/8s; f/18.0 1/6s

This set of exposures spans a large contrast range from bright grey sky down to dark shadows in the rocks; it varies the shutter speed so at least a few will make the water look like brushed cotton; it varies the aperture partly to cater for the range of shutter speeds, and partly so as much of the shot as possible has a frame with maximum detail before diffraction. Enough data that enfuse could find a good midtone maximizing local entropy (detail) at every pixel.

Each of the above had pixel-shift enabled for greater resolution, totalling 40 frames of 36MPel resolution. The shutter was open for a combined total of 12s.

Post-processing

I used my open-source Pentax K-1 pixel-shift workflow on each of the 10 images above, and then reused it again to blend all 10 together into a combined HDR average. Opening this in darktable, I proceeded to correct lens-distortion, finalize the crop (16:10 aspect-ratio, one of my favourites for landscape), set detail modules (no need for noise-reduction! some balancing of detail, local detail, equalizer modules though) and exposure, toning (including tonemapping and low-pass filter) and colour (Velvia). There are not many localized modifications, but there are significant grad-ND filters both down through the trees and, opposing that diagonally, up from the bottom of the frame, along with two instances of the vignetting filter (one significant, one just clipping the corners); there is also extra local contrasted masked into an area around the dead tree trunk. Finally I opened the image in The Gimp and ran the G’Mic filter suite including colour-grading twice (once conventionally, once with extra highlight/shadow duotone effects, blended together – this has the side-effect of changing the tonality in the green leaves to make it look brighter/sunnier than it actually was). A tweak to the curves to lift the overall gamma and then I overlaid my favourite texture image, a photo of a sheet of Hahnemuehle Photo-Rag paper, in soft-light mode to soften the contrast and add a small amount of texture into otherwise barren areas.

Why this Workflow?

Working this way hits a sweet-spot in terms of convenience and image-quality.

I did not fall in the river. That’s a good start.

With such a wide field of view, every centimeter counts when choosing the location. With the 15-30mm lens I was able to experiment, iteratively varying location and focal length, until an optimum position was found, all the while seeing exactly what the final composition would be in live-view.

Pixel-shift – moving the sensor around in a 1px square pattern – works as a great way to increase the resolution.
The alternative would be to shoot a panorama, but that would still require HDR blending of frames as well as risking motion-artifacts in the trees; with just HDR on its own, the ghosting of the leaves from averaging multiple frames is a more pleasant indication of movement rather than errors in stitching. Additionally, shooting a panorama would require just as much care over camera position but would not allow a preview of the composition.
As a hybrid option, with cameras that lack pixel-shift or equivalent technology, one could compose approximately and then vary the tripod position subtly to emulate hand-held camera-shake; this is almost identical to pixel-shift in terms of super-resolution, but varying the camera position risks introducing artifacts from lens-distortion and parallax between foreground and distant parts of the scene, that pixel-shift avoids.

Additionally, shooting every frame 4x over, automatically, increases the overall exposure time into multiple seconds, even in daylight, which avoids the need for Big Stopper-type filters (especially handy on a lens that would require a special holder for such).

The Dumpling

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:

Portknockie

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:

The approach to Bow-Fiddle rock at Portknockie.
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.

Birnam Hill: Hunting the Highland Boundary Fault

I’ve been to Birnam Hill and Duncan’s Hill area at least six times, so it made a good testing ground for the new Pentax K-1 camera.

It wasn’t the best of days for landscape photography – a bit early in the day for what little light there was to be really photogenic – but there was a moment when the sun broke through and illuminated some birch trees on top of Duncan’s Hill most beautifully:

For some years I’ve known the Highland Boundary Fault crosses the A9 around Dunkeld/Birnam area, but never really pinpointed the exact location.

On my first visit I walked around Duncan’s Hill through Birnam Wood and Rochanroy Wood: I observed a particular lump of rock exhibiting clear strata sticking out of the hillside:

As I passed the edge of the established woodland, there was a pronounced drop of about a metre to the level of the new conifer trees to the right. And I wondered if this was a particular noted geological formation.

Highland Boundary Fault, Birnam Hill

Three paths: this one leads down the line of the Highland Boundary Fault

On more recent visits I geotagged the location and compared with the British Geological Survey’s maps to see the rock types change either side of the dip – till, changing to slate and grit and then to psammite and semipelite typical of the Highlands.

On further investigation with Google Earth, the photo on the corner of the dip is right on the line of the Highland Boundary Fault itself, running up from Rohallion Loch through the lodge, round north-east turning easterly across the A9 south of Birnam.

My photo pinpointed right on top of the Highland Boundary Fault

The previous photo pinpointed right on top of the Highland Boundary Fault

Got it! Clear confirmation. Right on the money, first time 🙂

The path continues across a pronounced dip in the landscape before continuing up the other side to Stair Bridge Viewpoint and the King’s Seat on Birnam Hill.

Of course my favourite clear pure waterfall was still running:

The path affords some excellent views back of the Highland Boundary Fault cutting across the landscape:

And finally, as far up the hills as I wanted to go that day, at Stair Bridge Viewpoint I was rewarded with a clear landscape vista over Rohallion Lodge to the Lowlands to the south:

Glen Lyon

In the middle of January, I went for a drive around Glen Lyon. There was enough snow lying that the road was slippy on corners, so I didn’t get anywhere near as far in as I would have liked, but still, the light was a special kind of low cool glow.

Just a few twists along the road into Glen Lyon from Fortingall – we’re going that way into the glowing light, folks.

Trees draped like a fuzzy fir coat over a snowy mountain

 

This is a pretty commonly shot view from a small layby – but beautiful in the cold winter light, showing the shapes of craggy mountains:

A beautiful view – rugged crags descending to a smooth glacial U-shaped glen

And that was as far as I dared go for the snow. Turning back, I stopped by the roadside to check out a particularly photogenic little lochan lurking on the edge of the forestry:

Snow resting on a frozen lochan, Glen Lyon – I loved the way it sits on the edge of the forestry.

And I just had to take a photo of the beloved Doglet while I was there 😉

The one and only…. 🙂

By the side of the river, dusk was long gone and the blue hour had well and truly set in.

Landscape, Photography and Land Management

This is going to be a long post, drawing on several disparate areas of experience and interest. Welcome to my mind…

Photographic Influence

Cirrus clouds above a line of old beech trees, Portpatrick

Nice beech and hawthorn trees – shame they aren’t there any more

The Highlands are not like 18th-century Venice. On driving around – which you can do around here – the landscape is raw, rugged, elemental, positively harsh on a cold day. We do not sit around in powdered wigs playing the harpsichord of an evening.

It is my opinion that landscape photography exists not to make merely aesthetically pleasant images, not even to convey a “feeling” from the photographer’s mind in the name of art, but rather to show and tell forth something of the landscape.

It is all too easy to go for a stroll, to get out into “nature” seeking photographs, to see only the shapes and forms of the land, hopefully cover it in contrasty dappled light; but if that is all that is seen in a photograph then it is the most absurd way to trivialize larger forces at work.

Worse still, it’s even easier to get into a mentality of visiting only known-good photo locations. “Saturday afternoon, Falls of Bruar” – nothing against the Falls, far from it, but it becomes a photographic rut devoid of sense of exploration.

I used to have a motto: “no landscape photos without saying something about the rocks you stand on”. It’s still a good thought, but even though the geology might date back 3.5 billion years, that is only one aspect of pertinent story, perhaps even the cheap and comforting option – looking straight to Old, bypassing the anthropocene; it reduces taking a principled stand to throwing out bland “statement”s or little stories and/or personal feelings, offensive in their inoffensiveness.

The PSNS Experience

A couple of months ago I attended a lecture at the Perthshire Society of Natural Science (PSNS), part of the “Curious Minds” series; the presenter worked for SEPA at Stirling University, and he spoke about Sustainability. Being brutally honest, it was not the most approachable of talks: a business person speaking from a mind of systems-thinking about corporate matters, with that peculiar management tendency to present a metaphorical briefcase of ideas supposed to be complete but leaving one wondering what nuance is missing – that’s not likely to engage the common individual who only wants to know how best to run their own house. I couldn’t help thinking of the only two occasions I’ve had any dealings with SEPA – first to ask how to dispose of film-processing chemicals and second for maps to avoid flood areas when buying a house; if SEPA are to offer the public a service, they have a PR hurdle to overcome…

However, I came away with the seeds of several thoughts that have since germinated.

The lecturer explained how SEPA sees companies on a spectrum from “climate criminals” (knowingly damaging the environment) through careless to compliant to champions. A lot of words containing “C” and “A” and a nice gradation from red to green, but that illustrates the systems-think.

More usefully, SEPA has expanded their remit so they now see Scotland from three points of view: there’s the environment which they still protect for its own sake; there’s social (concerning wellbeing when people go for a walk in the forests); and there’s an economic aspect.

Experiences of Farming

For lack of reason to the contrary, I’ve always kept an open mind opinion about livestock farming. As a confirmed carnivore, living somewhere between town and country, it’s not easy to see bucolic bliss as harm. However, in the past five years there have been three experiences that sounded warning bells.

First: in Galloway, I spent 7 months living in a run-down farmhouse in the middle of a livestock farm on a nondescript C road. If we left the gate open, sheep would come and mow the lawn and cows walk past the study window and fertilize said lawn on their travels. It’s all very well feeling close to “nature” when the sun shines, but when it rains and the slurry runs 4 inches deep corroding your boots whilst walking the dog, it is far from pleasant. It also “never snows in Galloway”, which doesn’t explain the 3′-deep snow that winter, requiring the farmer’s assistance to dig out the surrounding roads – which were made impassable by his own tractors bouncing along compacting the snow into undulating waves of ice in the first place.

Second: also in Galloway, when I spent 15 months living next to a different farm: there was a beautiful line of old beech and hawthorn trees running up a small hill, just round the corner from where we lived; the farmer chopped them all down to make way for root crops to feed his sheep.

Third: two years ago, I went for a walk along a glen and found a particularly pleasant viewpoint, a U-shaped glacial valley with corrie lochan and lonely pine tree in the basin.

The light and landscape that provoked further exploration

 

Seeking to revisit and explore further, I researched the area on Google Earth and figured, with a choice of two, the better track would be one running up the south/”left” side of the glen to reach further into the mountains. So a month ago I set forth, with young dog on a lead beside me, to explore.

About 300 yards from the carpark, we rounded a corner and saw a herd of Highland cows and calves. By chance, the farmer came by in his Landrover at exactly the same moment and said not to take my dog any further. Fair enough – answered my dithering wonderings on the matter pretty quickly – and the exchange was pleasant enough.

However, that does not explain why, having driven off ahead of me, he promptly shut and padlocked a 6-foot-tall gate across the path, leaving me and my dog on the wrong side with the cows.

Inconsiderate farmer shut this gate right across the path, blocking my escape with a young dog.

With no way through or around the gate, I had to persuade my dog to climb precariously over that ladder, knowing that if one paw slipped he could be seriously injured.

As for outdoor access code – “right to roam” – it would have been more considerate if they had erected some sign warning of impaired access nearer the carpark…

With three strikes against livestock-farming kind, it’s time to start formulating an opinion.

Connected Thinking

So after a bit of a delay we rejoin the walk along the glen, this time going down the right side of the river instead.

Realisation dawned.

The first realisation was that the view I had seen a couple of years previously relied on a trick of perspective – the grassland appears continuous over distance while actually the river lurks below the level.

As I reached the furthest point of my walk a few miles into the glen, turning back, I observed how the river had cut straight vertically down a metre or two, exposing dead tree roots in the bank.

Half-way back, I noticed dead trees all along the river bank, and just off to the side of the path I found a large expanse of land full of the bleached white remains of pine tree roots and it hit me that this was a peat bog – a genuine example of the kind of thing one reads about in “the Highlands”, as though that were some far-off place – well here we are, soil/mud/peat at our very feet.

Genuine peat bog, full of bleached white roots and remains of pine trees

And so I looked at it through SEPA’s eyes. Environment + Social + Economy <= Sustainability.

Following research, peat is deposited at a rate of about 1mm per year, so the 1.5-2m depth of peat beside the river corresponds to 1500-2000 years’ accumulation.

What we have here is not the wilderness beloved of landscape photographers, it is barren.

The interplay of light and shape and form of the landscape is utterly irrelevant while the natural pine trees that should be here lie dead in a large carbon sink, their place taken by monoculture fenced-off in enclosures for commercial gain. The parts of the glen that are not directly peat bog are bare through grazing of livestock whose methane and CO2 emissions are a major contributor to global warming. In the words of Henning Steinfeld, Chief of FAO’s Livestock Information and Policy Branch: “Livestock are one of the most significant contributors to today’s most serious environmental problems. Urgent action is required to remedy the situation“.

This is not wilderness, it is barren. It is not a wonder of nature, but artificial. It is not contributing to society’s welfare but its unsustainability harms the planet.

Sometimes, one has to remove the rose-tinted sunglasses and see how one glen encompasses in every aspect a microcosm of all kinds of problems. Just because it’s a sunny day does not make it a happy story.

What Next?

I’m still thinking about it. I’ve spent long enough wondering if certain environmental charities are “a bit hippy”, but the facts are irrefutable: that glen stands for the worst combination of (un)sustainability factors. Peat bog itself is a valuable ecosystem, but given the choice I would far rather have the pine trees back that belonged there in the first place. The idea of rewilding meets with favour. While I would not want to join or recommend any “-ism” (vegetarianism or veganism being defined in terms of negative ideologies), I am also in favour of taxing the supply of meat and other livestock products to better reflect the true costs, including environmental factors.
