Along Some Sympathetic Lines

23 February – 27 April 2013
Opening 7pm, 22 February 2013

Or Gallery, Oranienstr 37, Berlin 10999, Germany

Or Gallery is pleased to present Along Some Sympathetic Lines, an exhibition of artwork by London-based artist Martin John Callanan, and an archive project by curator Liz Bruchet. The exhibition considers the poetic possibilities of data and its documentation, and the tenuous process of making meaning.

Martin John Callanan is an artist researching an individual’s place within systems. Callanan generates and reworks photographs, letters and electronic data into evidence of exchanges – between the individual, the institution and the networks of power that intertwine them. The exhibition presents four of the artist’s series: The Fundamental Units, the result of amassing millions of pixels of data, to photographs, in microscopic detail far beyond the capacity of the human eye, the lowest monetary unit of each of the 166 active currencies of world, only to enlarge and print them to vast scale; Wars During My Lifetime, an evolving newspaper listing of every war fought during the course of the artist’s life; Grounds, an ongoing photographic archive which charts ‘important places’ in the world where security restrictions limit the image to the carpeted, tiled or concrete floors; and Letters 2004-2006, Callanan’s correspondence with various heads of states and religious leaders which implicate them in conversations that question their very rationale of their authority. These acts of excavating, accumulating and visualising data draw out the sympathetic aspects within documentation and in so doing, mark and disrupt the underlying power dynamics.

A second gallery features an archive project by London-based curator Liz Bruchet. The display of ephemera from the personal archive of the curator’s grandfather, a Canadian insurance salesman and aspiring radio presenter, takes its inspiration from a found audio recording – part monologue, part autobiography, and part radio show – made in 1974. Harnessing the impulses of the collector, archivist and biographer, the curator reasserts her role as custodian and caretaker to nurture narratives and give weight to the subjective remnants of one man’s life.

This exhibition is curated by Liz Bruchet.

The exhibition is possible with the generous support of Or Gallery, the National Physical Laboratory, and UCL European Institute.

Big photos of little coins: National Physical Laboratory

National Physical Laboratory (NPL) wrote:

Martin John Callanan of the Slade School of Fine Art at University College London contacted the National Physical Laboratory (NPL) as he wanted to put together an exhibition featuring large images of the lowest denomination coins from around the world.

Petra Mildeova from NPL’s Advanced Engineered Materials Group demonstrated that full colour images could be taken using an infinite focus 3D optical microscope. Five coins were imaged (containing over 400 megapixels), allowing coins of less than 20 mm diameter to be printed as 1.2 m diameter images.

Martin John Callanan described the images as “really stunning” and is exhibiting them at the Galleria Horrach Moyà in Mallorca, Spain, in an exhibition entitled ‘The Fundamental Units‘ (referring to the smallest denomination of coins on display and not as a result of working with NPL, the home of fundamental constants in the UK). He now hopes to enhance his exhibition by imaging a further 161 coins, one from each of the other countries around the world that use them.

The images have attracted interest from the British Museum and were featured by New Scientist as their image of the day on 4 December 2012.

The mapping of large areas at very high resolution is becoming a more regular requirement. In fact, the capabilities of the microscope used to produce the images of the coins were barely stretched, as they were only in 2D. Using the Alicona Infinite Focus optical microscope NPL is able to acquire 3D datasets from large areas, which can be used to study worn surfaces on a gear, drill bit or metal punch and hence produce a detailed measurement of the volume of material lost by wear of the component. Such quantified volume measurements can then be used to determine the best material or operating practice for a given material grade.

Back-to-basics money shot shows a cent’s battle scars – New Scientist

The euro has taken a bit of a battering of late – and not just in the financial markets. As you can see for yourself above, the surface of a 1-cent coin, while smooth to the naked eye, is pitted and scarred when viewed through a powerful microscope.

To create this image, artist Martin John Callanan, a fellow at University College London based in the Slade Centre for Electronic Media in Fine Art, worked with Ken Mingard, Petra Mildeova and Eric Bennett at the UK’s National Physical Laboratory in London. The team used an optical microscope to create images of the lowest-denomination coins used in Australia, Burma, Swaziland and Chile, as well as the transnational euro. They took standard coins that had been in circulation and left the microscope to make 4000 tiny exposures overnight. It then took three days of processing to stitch these images together to create each final, 400-million-pixel version. The zoomable picture above is a low-resolution version.

The coin images are part of an ongoing series called The Fundamental Units in which Callanan explores “the atoms that shape the global economy”. Ultimately, the series will encompass all 166 of the world’s active currencies that use coins. The first five are on display as 1.2-by-1.2-metre prints, along with more of Callanan’s works, at the Galleria Horrach Moyà in Mallorca, Spain, until 17 January 2013.

Rhizome Editorial: The Fundamental Units

How did this collaboration with National Physical Laboratory come about for your project The Fundamental Units?

For six months I was having tests run all around the UK on different types of microscopes such as scanning electron microscopes, at different institutions, universities and testing laboratories. The Curator of Modern Money at the British Museum suggested an idea which eventually lead me to the National Physical Laboratory.

I ended up at the Advanced Engineered Materials Group which is part of the National Physical Laboratory, using an Alicona infinite focus 3D optical microscope.

They were really into experimenting and pushing the equipment. It took about a month of tests to get the results we see. The process involved Petra the scientist in charge of the machine writing programs to capture the data as a whole, as the machine is designed for looking in detail at one tiny part of an object. We crashed it several times working out the right solution. Each coin, which are generally around 18-20mm in diameter, take a whole night to capture. Then computers run for three days assembling the data into extremely high resolution photographic images. We are talking files too big for normal image editing software such as Adobe Photoshop. Each photographic print is from files with around 400 million pixels.

What did some of the earlier tests look like?

Many microscopes are not optical, they don’t use light, and therefore produce results that are removed from what we generally expect to see. A scanning electron microscope, for example (attached), produces images in greyscale and the electric charge greatly emphasises dust and dirt. Clean images could be obtained though sonic cleaning and plating the coins in gold, but this started to become very removed from examining these low value tokens of exchange.

Could you explain the choice to scan these particular coins? How did you get a hold of them?

There are currently 166 active currencies using coins. Using online market places and by contacting national banks I have found the lowest donimation coin for each of these currencies. At the moment, at the beginning, we have imaged one from each continent. All 166 will be imaged.

What are you working on currently?

Well, the UCL European Institute have just (five minuets ago) awarded the research project funding to image the currencies of: Bulgaria, Croatia, Denmark, Hungary, Latvia, Lithuania, Poland, Romania Sweden, and the UK.

As well as this I’m working on several larger works including archive the hugh photograph archive for Grounds grounds.greyisgood.eu
