Last week I had a spare hour in London between meetings so I thought I would go to Landscape Photographer of the Year exhibition at the National Theatre its on until 9th February 2013. I really enjoyed it – one of the images I liked was by Heather Athey “A bracing morning” and so I thought I stop by Tynemouth on the way home from Old Hartley to check it out – especially as there was a bit of surf. It turned out to be far more interesting than I expected.

North Pier Tynemouth

You drop down the hill next to the priory entrance and park on the headland above the sailing club. Then walk towards the gated entrance to North Pier past the sailing club. On the left of the entrance is a viewing ‘terrace’ and some steep steps down to the beach. I arrived at 1000 with a tide of about 3.2m above datum – I guess you can get on the beach anywhere below 4m but there is a surge that caught me mid thigh a couple of times when I had been standing on dry rock (my new Paramo Aspira pants coming to the rescue) so be careful.

The view is amazing and awe inspiring. In early February the sun is south of the pier so you don’t get the light like Heather found – I need to check The Photographer’s Ephemeris to see when the light might be good.

Anyhow it seem the pier’s construction took over 40 years (1854–1895). In 1898 the original curved design proved inadequate against a great storm and the centre section was destroyed. The pier was rebuilt in a straighter line and completed in 1909. As a consquence there are foundations beyond the wall on the seaward side that cause amazing waves with heights you normally couldn’t possible stand safely as close as I was on the beach. Got to go back in a heavy sea.

Three weeks ago I went to St Mary’s lighthouse with a low tide and noted a sunrise shot of St Mary’s Lighthouse was going to come from further north – probably around Old Hartley. So with a high tide at 0710 with 4.7m and sunrise at 0753 I thought it was good chance!

It was pitch black at 0700 when I arrived at the car park (see map below) and there was one photographer in the car park setting up (sorry forgot your name – let me know if you read this – he did mention Putting Photography First on flickr). Anyhow he pointed me at the dark line down the cliff south of the car park and said it was a set of steps.

Down the steps and I can say that its not a place to be with a tide 4.8m above datum! Also it wasn’t the view I was looking for initially – I’ll come back to it later (as I did about 0845 when the tide was 4.2m over datum and much more comfortable).

I walked south and attempted a few dodgy descents on the cliffs but finally found a low set of fence posts in an L Sr Mary's Lighthouse at Dawn with High Tideshape where the cliff had fallen away (see map) – its muddy and lose but you can scramble down to the beach where it was rocky and about 0720 when I got there – its probably safe with 5.0m above datum but there will be no foregound rock so 4.7m was ideal there are clearly other shots as the tide drops maybe as low as 3.0m over datum?

There was a dark cloud on the horizon and there was not going to be a horizon sunrise perhaps a cloud one. Anyhow by 0800 I decided to pack up and go to Tynemouth (next post) but predictably just as the tripod was on the bag the clouds changed pink – unpack 😉 – I also used my new Lee 100 system filters – a 0.9ND and 0.6ND Grad Hard.

By 0830 I set off back to the car park and on the way dropped down the steps to have a look – some great light.

I went onto Tynemouth – see separate post.

In post processing in Lightroom 4.3 I didscovered that the D800 is about 1.5 stop dark with the Lee filters – with my old Cokin filters I did notice this however the colour cast with the Cokin is not present with the Lee nor is the dreadful flare – this is a little flare if the filter is 90 degrees to the sun.

Slightly abstract title so no one will ever find it! I have been exploring photograph ‘design’ by which I mean composition, exposure, colour, contrast, sharpness/blur and capturing the ‘readers’ attention. I guess I am using ‘reading’ as I want to distinguish passive viewing of an image from participatory exploring of an image which potentially finds meaning. As you can imagine this could be a big post!

Single tree on snow field Northumberland-Prof Ian Purves-20130126-1136-3

To keep this focussed – how can you keep the image open enough so that it isn’t immediately obvious? So far techniques I have come across are:

  • Subject bursting beyond frame
  • Vectors heading outside of the frame
  • Movement trajectory outside of the frame
  • Gateway in/out of the frame
  • Cropping tight
  • Dark areas of contrast with ‘hints’
  • Metaphor
  • Questions not answers

This last one about ‘questions not answers’ comes from David Wards book ‘Landscape Beyond’ – in which he proposes that images that are questions invite us to explore. The other three sections in the book are on simplicity, a sense of mystery and beauty. Anyhow when the snow stopped and it is was likely that I could get the car somewhere (I really need to get a 4×4!) I thought I would step out yesterday. I had a conversation with my son Josh about simplicity in photographs, gave the example of a single tree on a hill and found some examples on Flickr. However I said I wasn’t aware of any local ones – he told me about the three trees near Black Callerton.

So here are a couple of images I took yesterday on a bright sunny cloudless day with fresh snow and a freezing wind. Despite the simplicity of the images there are things to explore and do leave me with questions that I have no answer.

Just had lunch and my favourite photographic critic, my wife, who said about the images “well there alright” and so asked what the blog was on, she responded “blimey your getting a bit up yourself!”. I think I better publish this and tidy the loft.

Personal learning notes

I was using the D800 and Zeiss Distagon T* 2.8/21 ZF.2 trying to get the foreground and tree in focus I upped the f-stop higher than normal as an experiment.

  • Diffraction (in softening of the branches) can be seen in the images over f/8.0 (especially f/16)
  • It was bright so I left the tripod in the car; so I couldn’t use mirror up – I can see a bit of mirror slap in the f/5.6 images (again in the branches) – don’t be lazy!

In my safari photographic technique blog in Dec 2012 I noted a few personal learning needs about autofocus:

  • What “autofocus area mode”? – I am using single-point AF
  • What “autofocus mode”? – I am using AF-A
  • What “AF-C priority selection” – I am using “Focus” on D7000 and “Release + Focus” on D800
  • Which is the best wildlife lens?

What I didn’t comment about was my book publication attempts – I have now created two books, Safari Journal and The Himba Trail using Lightroom 4.3 and Blurb. The good things are that they are great quality and they really engage people ( unlike a slideshow ); the downside is that textually and story-wise I have been personally disappointed in both the software and my ability. In addition the LR upload to Blurb timeouts all the time meaning it can take days to upload a large book in several attempts – if you upload the same book as a print ready PDF it takes 15 minutes. I am also at that stage where I would like a community of practice so I can develop further … I will save you the long story … I talked to Eddie Ephraums (great bloke) and enrolled on a week workshop session with him Joe Cornish and Paul Sanders entitled “Bigger Picture Portfolio & Book Project Workshop

Well Eddie is great at capturing your learning needs and at the end of the conversation he said anything else … I laughed and said well it was bit out of court but I had a wildlife issue with autofocus. Eddie said immediately I had to meet Andy Rouse and why didn’t I go down to the Outdoor Show where he was talking next week. So I have and I’m on the train home!

Not only did I meet Andy Rouse who is a fun larger than life and very personable bloke he is exceedingly knowledgeable … but I was also really lucky to also meet and listened to Florian Schulz (see his “Chasing the Light” and his new book “To the Artic” from Amazon).

So the answers to my learning needs are [Updated on 01/08/2013 see blog] …

  • What “autofocus area mode”? – I am using single-point AF [CORRECT – except birds in flight with no confusing background let the camera use its abilities)
  • What “autofocus mode”? – I am using AF-A [INCORRECT – always use AF-C – Florian uses nothing else]
  • What “AF-C priority selection” – I am using “Focus” on D7000 and “Release + Focus” on D800 [CORRECT]
  • Which is the best wildlife lens? – There is no strict answer to this it depends; however both Andy and Florian use 200-400mm f/4 lens for 80-90% of images as they are sharp, fast, lighter than the primes and you can reframe.

Another thing I learned was that Andy and Steve both pushed was have a project that you can keep coming back to – there is no better way to really see the potential images and learn.

Final note I have to thank Steve Watkins, Editor Outdoor Photography for organising such a great lineup (the other guys where great but not the focus of this blog – Pete Webb and Tim Allen). Steve was also a great listener and was really helpful.

Well I saw a few images of the sea stack and rock arch just off Lizard Point on which Souter Lighthouse stands at Whitburn (note: several images mistakenly call the point Souter Point – which is further south and seems to have its own arches). So I started to look for any information on access but couldn’t find anything on the internet! As the tide was going out with a low tide at 1028 and sunrise was 0822 I thought well it can’t be that hard … oh dear. Looking at satellite images on google maps there seemed to be a path down to the beach (Byer’s Hole) which is to the south of the beach on which Lizard Point is at the North end  (this beach is not named on OS maps) – still with me. So off I went and got there at 0715 (ended going through South Shields due signs at the Tyne Tunnel – needed the A1300).

Fishermen at Byer’s Hole near Soutter Lighthouse Well the lighthouse car park on the map had a gate which was closed – so I parked across the road (see map below). Entering the gate on foot there was a tarmac path just behind the gate which I followed (it was pitch black but I had a head torch). At the end I went to the cliff edge and turned right and there was the path! By now it about 0730 so 3 hours from low tide (last new moon was 2 days ago so its a spring tide). On the beach (Byer’s Hole)  I went north towards the point and met a fisherman he said he’d never gone round the point as you could get caught by the tide and didn’t know any other way into the next bay. So I had a look at the point and the tide was too high. As a consequence I spent the next 20 minutes exploring the cliff top in the dark – there is no way down. I headed back to Byer’s Hole and met Craig McNair we got down to looking at the sunrise and taking a few shots from the cliff top.

Sunrise from point South of Byer's Hole near Souter Lighthouse W

When we had finished it was about 0900 so I set off to see if I could get round the point. The fisherman was still there, eating some sandwiches! Yes it was just possible to get round climbing the low rocks (the higher rocks look OK but they are not on the other side) so I had 1.5 hours to low tide – therefore at least 3 hours. For those wanting to do this you need to understand the tide tables – the tidal height was 1.4m from datum (I think 1.5-1.6m is minimum to get round if you balance a bit on the rocks rather than wade) and low tide was going to be 0.8m from datum and it was two days after a new moon. Please understand the tides or you will be trapped I could see no way out further up the beach. The climb round the point wasn’t hard but there was about 30cm of water to wade at one point (you need wellies). The walk North up the beach was easy the rock not at all slippy and the arch at these tidal heights was easy accessed. I was back at Byer’s Hole by 1030 and could walk easier round the point.

I had set off with the hope of a sunrise through the arch – I don’t believe this is possible at any time of the year but have seen one which is perhaps 30 minutes after sunrise and in July – I think it must be one arches of the two further south [note 14-01-2013: checked it is the further south one … so it is not possible]? But none the less pleased with the 100 shots I took and the few I selected, it was fun to explore – a great morning 😉

Why did I go the forecast said it was –1C and rain! Anyhow I did go and there was a glow on the horizon from around 0730 – a couple of vaguely decent shot were to be found before it started sleeting and I couldn’t keep the lens free of water.

St Mary’s Lighthouse was built on St Mary’s Island in 1898 on the site of an old monastery which used to have a light to guide ships – a history of the island can be found on the friends site.. The current lighthouse is 38m (120ft) high and has a tidal causeway joining the island to the mainland. It was decommissioned in 1984 but acts as a museum.

I thought I might be able to get a sunrise from behind the lighthouse where there are some large pools which should be clear at mid tide. The tide today was 0944 so was going out whilst I was there. It isn’t possible to get pre-sunrise shots on the island and include the lighthouse so I focussed on the rangefinder which is behind the lighthouse. Looking at Flickr it would seem the car park further North near the mast (Old Hartley) it the best spot to be – though I might try again someday with the pools behind.

Personal Learning Notes:

  • I need to get a waterproof cover for camera and lens! [Note 14 Jan 2013:  Got a Storm Jacket SLR PRO Medium from Wex]
  • Check out Old Hartley [Note 2 Feb 2013: I did see post!]

So yesterday Simon Owens recommended Chemical Beach in Seaham and I was intrigued by the sea stack, the posts, the wheels (but these would be under water due to tide) and the arch. Plus looking at few other photos was encouraging. The weather forecast was good and so it was a go – the plan was see what there was but also try to get the sun through the arch. Great metaphor for drawing you into a new day – loved it since the “The Bridge” in Namibia!

Sunrise at The Bridge at Spitzkoppe in Namibia

Sunrise at The Bridge at Spitzkoppe in Namibia

Simon gave great directions (see map below) and I parked in the dark in the first parking bay, hopped over the barrier and headed left. Really glad of the new wellies it was steep and muddy – the path curves back on itself as it goes down and you have to hop over the large granite boulders – not easy in the dark! On reaching the beach it’s a shale one and there was a feint gold glow on the horizon.

The beach got its name from Seaham Chemical Works which occupied a nearby site in the 1860s. By the 1890s, both it, and Seaham Iron Works, former occupier of the Dawdon Colliery site at Nose’s Point, were ‘disused’. The wooden piles on the beach were supports for a rail track used by wagons for tipping mine waste from Dawdon Pit into the sea. In the middle of the beach is a magnesian limestone stack (Liddle Stack) and the far end is Nose Point where the arch is through to Blast Beach.

It was 0730 by the time I got to Nose Point at the far end and it was clear the tide was too high (high tide 0944 neaps) to get round the first part of the nose you clearly need low water (and probably not a neaps one) Dave Brightwell has a great photo of the arch on Flickr (see right) – even this is too high a tide to see through but I am sure it can done. So I got down to looking at the stack and the posts.

Thanks Simon, some of the photo’s below (click for lightbox) and perhaps some others in my North East Gallery.

Personal Learning Notes:

  • Visit Chemical Beach at low tide to check out the arches
  • The D800 auto colour balance gave different results today compared with yesterday and so did Lightroom? Back to explore colour balance with ND filters!

Well having spent what remained of December editing Namibia photos and then cooking for the rest I thought it was about time I got out! Inspired by a couple of photo’s in one of my Christmas Presents Joe Cornish’s book First Light, having checked a) the weather (good … possibly a little fog), b) sunrise (0832) c) angles in the The Photographers Ephemeris and d) tide tables (high tide – neaps @ 0751) it all looked perfect! I got up at 0545 for a 50 minute drive (top down) and set off for Embleton – pitch black when I got there so thankful for the head torch I set off on memory of the path … took a detour along the beach 😉

I had in my mind silhouetted menacing castle high above me with matching menacing cloud pointing towards the doom in the castle! I wanted to pull in some of the round (cannonball) basalt boulders (random link to Namibia) to add to the metaphor and was hoping for a golden glint on the rocks that Joe had found. Sunrise at Dunstanburgh Castle, NorthumberlandAs an aside my wife loves these blurred sea scenes so I set out to add them as much as possible – as it stands she is my only critic! … and the kids will tell you … criticism is one of her specialities (she’ll never read this) …

To being with it was very dark stuck with 30 sec and f/8.0 and shifted ISO up. Unfortunately I had forgotten my glasses so I couldn’t trust my assessment of the liveview on close focus so broke a rule and shifted to f/11.0 and guessed focus (using my Zeiss 21mm). The feelings I had hoped for where present … did I capture them? As the light arrived I stuck a ND8 filter on to keep the shutter slow. Simon Owens arrived he’d been South first and decided the North was a better option, its great to meet people on dark beaches 😉 He gave me a great idea for tomorrow … you can wait!

- 20130105 - 075459 - Prof Ian PurvesSo having processed the images I think I got there … except the golden light (it was red). Biggest problem in post processing was the white balance. Especially the ND8 effect it was a real challenge deciding how to pitch it … go with the Lightroom dropper (Temp: 20,000 and Tint +50) or stay darker and more blue/green … I did the later. Interestingly so did Simon.

Also the filters created a slight vignette … I have known for awhile I needed to change my Cokin set … what to do Lee or Hitech Pro?

There are more photo’s in the Northumberland gallery and one image I took a different white balance approach is below.

So for the first blog of 2013 lets go back to October 2012 – we were off to Namibia it was booked. I anticipated lots of great landscape photographs (boy did we find them) and whilst I had two D7000’s following the Botswana trip I was not really happy with my 16-85mm f/3.5-5.6G ED VR AF-S DX NIKKOR plus I felt it was time to make a leap to full frame. The Nikon D800 was getting great reviews and holding the camera it felt great plus it didn’t have the D7000 left hand mode dial which I find is always changing when knocked (silly issue I know).

What to get with a D800?

Well I took a few test shots and then did some timings on the laptop for both load and Lightroom processing … and I bought a new Macbook Pro 15” Retina Display 2.6GHz with SSD and 16Gb RAM … on this machine one image takes 23 seconds into Lightroom through Ingestamatic onto the SSD and backed up to USB 3.0 external drive (this is the fastest procedure by x3!) … on the old machine (well specified Samsung 9 series) forget it. Also you don’t have wait a whole year to zoom in on an image in Lightroom to check on sharpness. Since I got back LR4.3 came out with Retina support.

The next was which wide angle lens so the choice seemed to be the AF-S NIKKOR 16-35mm f/4G ED VR (see Ken Rockwell) I was put off the 14-24mm f/2.8G ED AF-S NIKKOR due to it’s lack of ability to put on filters (at least not without an expensive approach) and the weight. However at the time there was no stock in the UK and so I kept reading. I came across Lloyd Chambers site and walked into the Zeiss world. His reviews sold me on the Zeiss Distagon T* 2.8/21 ZF.2 – a description from the Zeiss site …

The Distagon T* 2,8/21 is a super wide-angle lens and is the leader in its range. Thanks to its aperture of 2.8 and its non-reflecting and virtually distortion-free characteristics, it will help you create spectacular compositions full of variety, dramatic contrast and deep, vivid colours.

… it’s all true. Also I found Robert White their usual helpful self and got both the Zeiss and D800 from them in a few days.

Within a couple of days I was up early and off to Lindisfarne and Bamburgh Castle then onto Hexham fireworks and then up early again for sunrise at Bamburgh Castle (see more images in the Northumberland Gallery).

Focal plane a touch back from infinity @ f/8.0

Focal plane a touch back from infinity @ f/8.0

I was amazed. I also could not see any diffraction issues that Lloyd Chambers talks about (in more depth here), however I mostly used f/5.6 and occasionally used f/8.0 and f/11.0 – jumping ahead of myself – with more experience I have in general rarely stopped down more than f/8.0 and use f/5.6 especially if focus is 5m or more. Actually whilst discussing this I mostly focus on infinity and nudge it back so the edge of the ∞ is inside the Infrared mark at f/5.6 everything from just under 3m to infinity is in focus (plus at f/2.8 infinity is in focus – so always a safe spot). If I am looking for foreground focus I get my composition right and use liveview to focus then decide if I want infinity in focus – at 2m at f/11 it is – so it’s only under 2m there is any issue and to be honest it’s nice to have the background out of focus.

Focal plane 40cm @ f/2.8

Focal plane 40cm @ f/2.8

The manual focus felt a real backward step – it is not – it such a great feeling to be back in charge of focus and to think again. In addition I had forgotten what it felt like as these auto-focus lens have such small “throws” the Zeiss is so perfectly balanced you can easily focus down to 22cm (which is only about 3cm in front of the lens hood).

So back to the timeline, I took over 1,200 landscape images with the Zeiss 21 and D800 in Namibia the percentage wastage was staggering small at 5% compared to 50% on wildlife using AF.

What are the highlights of the Zeiss Distagon 21mm and D800 combination?

  • It is a very easy combination to use in the field you can “feel” where you are with focus even if your eyesight is declining (though I need liveview for foreground focus)
  • The micro-contrast and colours are amazing
  • The lens is so sharp
  • The moustache distortion is visible, but rarely meaningful in a distracting way, and it can be removed easily in Lightroom but I don’t remove it! I used to with the Nikon 16-85 but the image doesn’t feel as good to me – I think the micro-contrast is disturbed by the algorithm?
Uncorrected distortion (Image A)

Uncorrected distortion (Image A)

Corrected distortion (Image B)

Corrected distortion (Image B)

I would be surprised if you can see much distortion (until you flick between them on the lightbox) it was the worse image I could find and needs a human artefact – however you can how see the effect of Lightroom’s correction if you look closely at the foreground plus the nice vignette goes
  • I really like the natural vignette at f/2.8 plus also the colour seems somehow a little richer
  • I have mostly stopped using graduated ND filters – what? – yup 14 stops of contrast in the D800 (i.e. local contrast/tonal differentiation) means that you can pull and push with minimal noise. Of course it’s nice to Expose to the Right (ETTR) to ensure you can pull without noise – of interest the “blinkie’s” on the D800 do exaggerate a little and can be pushed – but don’t rely on it and blame me 😉

Adjustment to RAW: Graduated filter (with Highlight -60) then global Curves; Highlight -60; Shadows +60; Sharpening +60; Contrast +8; Clarity +12 – very slight noise can seen in the sky which can corrected with Luminance smoothing +24


What are the lowlights of the Zeiss Distagon 21mm and D800 combination?

  • 21mm is a big field of view and in Namibia I felt I occasionally needed something between my AF-S NIKKOR 50mm f/1.4G and the 21mm (Oooo that’ll be the Distagon T* 2/35 … the f/1.4 is massive) but overall with 36Megapixels you can also crop!
  • The price was double the AF-S NIKKOR 16-35mm f/4G ED VR

I was not expecting how awe-inspiring Namibia can be. We arranged a three week trip driving around Namibia in a Landrover with a tent on top (supplied a brilliant company Safari Drive) and I researched the photographic possibilities. The red dunes at Sossusvlei and Deadvlei are high on the list, as is Spitzkoppe, these are very impressive but the unexpected was the landscape in general in the North West of Namibia (see my gallery) and the people. I found a book on my last day that I wish I had read before going Landshapes – The Geomorphology of Namibia it has no pictures but lots of drawings and gives you an insight on what you might see and the geology behind it (unfortunately it is not easy to get in the UK). I was also slightly handicapped by the distances –Marrienfluss Valley, Namibia we covered 3,600km off-road in 17 days – and the pressure to get places meant I didn’t take the time I wanted both to wait for light or explore the angles away from the track. My next trip to Namibia I hope to find a more leisurely pace so that I can try to capture the landscape.


Briefly – the geomorphology of Namibia stems from the Huab era (900-2,600 million years ago), given the Earth was formed 4,600 million years, or so, ago some of the rock in the Northern part of Namibia is the oldest on the planet! From around 300 million years ago Gondwana was covered by glaciers (it was over the South Pole) and many glacial valleys can be seen in the Namibia landscape. Finally a lot of the geomorphology was formed from the separation of Gondwana into Africa and South America (132 million years ago). In fact many formations in the Etendeka Highlands have matching formations in Paraná in Brazil.

Etendeka Tablelands in Namibia

After the breakup of Gondwana the dominant effect has been erosion. Around 70-60 million years ago Africa was lifted about 1km and there was initial a surface covering of sedimentary rock. This sedimentary rock has in general been eroded, especially as Namibia has been arid for millions of years and has minimal vegetation. Subsequent deep basins are filled up with sand (from the eroded sedimentary rock) and this has flattened the topography. However there remain many isolated igneous intrusions which poke through due to ancient tectonic upheaval. These igneous intrusions along with visible plate tectonics, eroded basalt features are now the dominant features in the landscape.

Rivers and Geomorphology

An interesting feature of Namibia is that water impact on the geomorphology is different than most landscapes. Back of Epupa Falls on Kunene River on the border of Angola andThe only perennial rivers in Namibia are shared with its neighbours; they are the Orange, Kunene, Okavango, Zambezi and Chobe. Each of these functions as a national frontier with limited irrigation potential. Most rivers are ephemeral in that they are mostly dry but run only for short periods following rainfall in distant mountains. Often the start of river flow is out of the blue and can come with a flood. Ephemeral River in NamibiaThe river will then run for 1-2 days. Although the ephemeral rivers of Namibia have dry sandy or rocky river beds for most of the year, they are conduits for subsurface flow and contain a number of wetlands defined as ‘shallow, swampy or marshy areas with little or no water flow’ or ‘waterlogged solid dominated by emergent vegetation’. These dry river beds are habitat for much of the plant and animal life in the desert regions.

Namib Desert

The Namib Desert is a major feature of Namibia, stretching 2,000 km along its Atlantic coast. The Namib’s aridity is caused by the descent of dry air of the Hadley Cell, cooled by the cold Benguela current along the coast. From the Atlantic coast eastward, the Namib gradually ascends in elevation, reaching up to 200 kilometres inland to the foot of the Great Escarpment. Annual precipitation ranges from 2 millimetres in the most arid regions to 200 millimetres at the escarpment, making the Namib the only true desert in southern Africa. Having endured arid or semi-arid conditions for roughly 55-80 million years, the Namib is also the oldest desert in the world.

Dunes in Sossusvlei Namibia

The desert geology consists of sand seas near the coast, while gravel plains and scattered mountain outcrops occur further inland. The sand dunes, some of which are 300 metres high and span 32 kilometres long, are the second largest in the world after the Badain Jaran Desert dunes in China.

So overall Namibia has large desert plains with amazing rocks surrounding the plains and large rock sticking through very Tolkienest! There is always a WOW around the corner or over the ridge.


Panorama of The Bridge at Spitzkoppe in Namibia

On the photography front I found the scale of the landscapes a challenge. Using a 21mm lens the large mountains in the background disappear. The foreground is limited to some amazing treesQuiver Tree Namibia, wind-rippled sand, dirt tracks and the occasional animal. I have just been given Joe Cornish book First Light for Christmas and wish I had read the section “On the rocks” the is a lot to rock formations and wish I had taken more telephoto views. Lightning at Twilight in Etendeka Tablelands NamibiaWe went in late Nov/Dec 2012, this is beginning of the rainy season and the thunder storms where fantastic – I’m going to take a lightening trigger on my next trip – although I managed a few amazing shots after sunset on repetitive shots at slow shutter. Finally, if you get a chance go in a balloon in Sossusvlei.
