Estuary

Tuesday, May 16th, 2023

Ten years ago on Thursday 16th May 2013 I was pleased to attend the opening of the exhibition Estuary, held to mark the 10th anniversary of the Museum of London Docklands at West India Quay, a short walk from Canary Wharf. I was delighted to be one of the dozen artists in various media to be included, with ten of my panoramic images from my work on the north and south banks of the Thames.

Estuary opening

I’d begun photographing the lower reaches of the Thames back in the 1980s, then working largely in black and white and my work concentrated on the then fast disappearing industrial sites along the river. At first I worked on the Kent bank on the south of the river, having a particular interest in the cement industry that occupied and had radically changed much of area between Dartford and Gravesend. Later I also worked along the north bank.

Estuary is a term that has various definitions, and both its upstream and downstream limits have, as Wikipedia states, “been defined differently at different times and for different purposes.” For my own purposes it has been rather elastic, usually beginning at the Thames Barrier and going east as far as it was convenient to travel by public transport, on foot or by bicycle from convenient stations. In earlier years I went further along the Kent bank by car in some outings with friends including Terry King as far as Sheppey.

The exhibition had come as a surprise. The ten picture in it were from around a hundred images the Museum of London had bought from various of my projects for its collection a few years earlier and I think the first I knew about it was when I received the invitation to the opening, or perhaps by an email a couple of weeks before that.

These pictures all dated from the early years of this century, those from Kent in 2000 and from Essex in 2004 and all were in panoramic format. In 2000 I was working with two swing lens cameras, a Japanese Widelux F8 and a much cheaper Russian Horizon 202. Both work with rotating lens and a curved film plane, invented by give Friedrich von Martens in his Megaskop-Kamera in 1844, but instead of the daguerrotype plates he worked with use standard 35mm film, producing negatives around 56x24mm.

The two cameras have a similar field of view horizontally around 130 degrees and have a cylindrical perspective which renders lines parallel to the film edges straight but gives an increasing curvature to horizontal lines away from the centre of the image. The image quality of the two is very similar but the cheaper camera has a rather more useful viewfinder.

By 2004 I had two further pieces of equipment which extended my panoramic photography. One was a new camera, the Hassleblad X-Pan, which had generally received rave reviews. I found it rather disappointing at first and it was only after I added the 30mm wideangle lens that it became useful for me. The X-Pan is a standard rectilinear camera design but gives negatives 65x24mm rather than the normal full-frame 36x24mm. The horizontal angle of view it produces with the 30mm is at the limits of rectilinear perspective, before stretching at the edges becomes too apparent, and is considerably less than the swing lens cameras at 94 degrees. The lens comes with a separate viewfinder that fits on the top of the camera, but does make operation a little less convenient.

The second, and very important for working along the north bank was a Brompton folding bicycle, which enabled me to travel the greater distances needed there. Of course I also used this and the X-Pan for later pictures elsewhere.

You can see more of these pictures in two sections of the Urban Landscapes web site, which also includes work by other photgraphers, both British and overseas. Some of the pictures I’ve chosen for today’s post were in the Estuary show, but others were not – I have a rather larger body of work to select from than the Museum, some of which appears in my book Thamesgate Panoramas.

Northfleet, 2000

The site has separate sections on the Thames Gateway in Essex and Kent, as well as from my Greenwich Meridian project in 1994-6 and a wider selection of panoramic work from around London from 1996-2005, though there is much more that I still have to put on-line. Some is also now on Flickr.


Swanscombe

Swanscombe, Kent. Sat 6 Jun 2015

I first visited Swanscombe back in 1985, when I was photographing along the south bank of the River Thames and Lower Thameside. Until the 1840s this area of North Kent had been relatively remove and rural, with riverside marshes largely untouched and valuable agricultural land on the higher areas growing food for the capital.

Portland Cement was patented by by Joseph Aspdin in 1824 and the later developed by his sone William, but the modern version of it was developed at Swanscombe by Isaac Charles Johnson, then manager of John Bazeley White’s cement plant. Johnson soon after left J B Whites to set up his own cement plants, including those nearby at Geenhithe and Cliffe, and Frindsbury on the Medway. In 1911 C Johnson & Co became a part of the Blue Circle Group.

The building of London’s sewers led both to a large demand for cement and also led the Metropolitan Board of Works to provide a specification for their needs which became the standard for Portland Cement. Portland Cement is the cement used in almost all concrete, mortar, stucco and grouting.

From around 1900 virtually all cement has been made in large rotary kilns, with flames heating limestone or chalk with clay-containing minerals at around 1500-1600 degrees Celsius. Water and carbon dioxide are driven off as the minerals combine to give silicates (mainly (tricalcium silicate, dicalcium silicate, tricalcium aluminate and tetracalcium aluminoferrite). Around 10% of world CO2 production which fuels climate change is due to cement manufacture, and smaller amounts of other polluting materials are also released in the process – hence the high chimneys of cement works. The small lumps of ‘cement clinker’ that emerge at the lower end of the kiln are then ground to a fine powder, often with added gypsum (calcium sulphate) or limestone to give cement.

Cement can cause burns and it readily absorbs water, hardening to form solid hydrated material and firmly embedding the sand or aggregate it is mixed with for most uses. Over many thousands of years the River Thames in this area had cut its course up to the chalk of the North Downs, and since the 1840s much of that chalk has been quarried, leaving deep pits with often fairly narrow strips left for roads through the area and housing. One of those deep pits now holds the Bluewater shopping centre at Greenhithe and others are filled with various industrial properties or housing. The industry over around 150 years completely transformed the landscape. But by the time I first came to photograph it, this post-industrial landscape was rapidly being reclaimed by nature.

Down the centre of the Swanscombe peninsula is the footpath, Pilgrims Road, leading down towards where a ferry once brought pilgrims on their way to Canterbury from a ferry across the River Thames from close by St Clement’s Church, still there beside the detergent works at South Stifford. Later clay was brought across the river from Essex to wharves for making cement, as well as coal, probably coming by coaster from the north-east to fuel the kilns. Ropeways or conveyor belts will have linked the wharves to the cement plant.

In 2012 I heard of the plans to transform part at least of the area yet again, into the Paramount London theme park, a leisure attraction along the lines of Thorpe Park, which would destroy the area as I knew it. Although I decided to come and photograph the area again before that happened it took me three years to return and do it, cycling around the area on a Brompton, (though occasionally I had to leave it a explore on foot.) Five years on, the plans are still plans and I hope to go back again next month.

With a few exceptions, the pictures here are wide-angle panoramics, with a horizontal angle of view of around 145 degrees and a vertical angle of view of roughly 90 degrees which results in a ‘normal’ aspect ratio of 1.5 : 1 – I usually took these intending to crop to a 1.9:1 ration but have left them uncropped. A few are taken with more normal wide-angle lenses.

On My London Diary you can see more of these pictures, and also read more about the area and my day there in 2015. The images display a little larger on that site.

South of the River 1985

In 1984, I more or less came to an end of my work on the River Lea (though I returned to it later) and the major focus of my photography shifted to London’s Docklands, and I’d photographed the West India and Millwall Docks as well as the Royal Docks, pictures from which I’m currently posting daily on Facebook. And later in that year I also went to the Surrey Docks, where work by the London Docklands Development Corporation was well advanced.

I was very aware of the political dimensions of the redevelopment, with the LDDC taking over from the elected local authorities and imposing its own largely business-led priorities which although accelerating the development distorted it away from the needs of the local area, and particularly away from the still pressing need for more social housing and for better employment opportunities for local people.

In those years I read every book in my local library on the history and geography of London, and began to build up my own collection of older works bought from secondhand bookshops and by post. Before the days of on-line listings I used to receive a monthly duplicated list of books on offer from a dealer I think in Brighton, and found many topographic and photographic items of interest, often very cheaply, and would look forward to receiving heavy parcels wrapped in several layers of newspaper. Yes, there was mail order before Amazon, and it was rather more exciting.

It was reading one of the books, Donald Maxwells ‘A pilgrimage of The Thames’, published in 1932 with his imaginative text and evocative drawings (some originally printed in the Church Times) that prompted me to walk in 1985 as he did from Gravesend west through Northfleet and Greenhithe exploring what he christened ‘the Switzerland of England’. As a rather more down-to-earth guide I also had the more academic ‘Lower Thameside’ picked up for pennies in a secondhand bookshop, which included a chapter on its 1971 cement industry by geographers Roy Millward and Adrian Robinson.

My series of walks traversed what was an incredible industrial and post-industrial landscape, altered on a huge scale by quarrying and industry, continuing past Gravesend along the riverside path past Erith and Woolwich to Greenwich and Deptford (areas also covered in my 1985 London Pictures), as well as walking further east to Cliffe and Cooling.

It was a project that I returned to for several years – and I went back to the area more recently when the Channel Tunnel Rail Link was being built as will as the occasional walk or bike ride over the years.
