World Photography Day: Documenting the build

Today is Photography Day, celebrating the photographers and the stories they capture. Here at the BPMA, we have approximately 100,000 photographs in our collections. As we ramp up to open The Postal Museum and Mail Rail, photography is playing an even more crucial role, documenting the transformation of our physical spaces.

Demolition has started at The Postal Museum site and we are eagerly waiting to get started in Mail Rail. Below are a few  photos of the building that will become our new home. The first showing it in its former glory in the early 20th century, the other’s what it looked like a couple months ago before demolition work began.

Adventures in Digital

Hello, my name’s Rose and I’m a student at University College London, where I’m studying for an MA in Digital Humanities. As part of my course I spent ten weeks completing a placement at the BPMA, working with Martin, the Head of Digital, and Rachel, the Digital Media Manager.

2014 06 01

One of the main projects I worked on involved creating 3D models of items from the museum collections using photogrammetry, which I wrote about previously. I’d already learnt a little about the techniques involved, and this project gave me some valuable practical experience putting those lessons into action. It was amazing to be given access to photographic equipment and modelling software, and to have the freedom to experiment with different techniques. I benefitted a lot from the Digital Team’s photography knowledge, and I’m very proud of the models our experiments produced! Check them out here: https://sketchfab.com/postal

Another project involved digitisation work of a different kind, scanning historical maps and documents. A highlight was handling documents related to the sinking of the Titanic, and learning about the Post Office and Mail Room which were on board. This really made me appreciate how unique a resource the BPMA’s collections are.

I also digitised the negatives of maps depicting different postal routes; it was fun to take a small piece of film and digitise it to reveal the detailed and colourful illustrations it held. Digitisation can help preserve the museum and archive collections and make them more accessible; it’s exciting to think these images could help engage people in the story of Britain’s social and communications history.

I really enjoyed my time at the BPMA as I was given the opportunity to develop so many new skills and to work on more projects than I have space to mention! I’m interested in seeing how digital technologies continue to play a part in the BPMA’s work, and especially in the new Postal Museum. My placement gave me a valuable insight into life in the museums and heritage sector, and I’m extremely grateful to everyone I met who took the time to talk to me about their role.

Photography mysteries from the Archive Stocktake

The (mostly figurative) dust has settled after our annual Archive Stock Take, when the whole archive team pulls together for a packed two weeks of communing with the collection. Sorting, listing, arranging, appraising, auditing, measuring – basically all the huge or awkward jobs we can’t fit into the rest of the year, but that are becoming ever more important as we prepare to move our collections to their new home at The Postal Museum.

Adam and Lydianne measuring boxes

As ever, we’ve been left with a few questions that we need to answer – and we’d like your help with them!

One of our tasks was sorting through boxes and boxes of photography, weeding out the prints and negatives that we already had and finding the material relevant to our collections to be preserved. Often we couldn’t find any notes at all about when or where the images came from, so the biggest challenge was to try and work out what it was we were actually seeing.

This is where you come in! Are you able to shed any light on where the following photographs were taken? If so, we’d love it if you could help us to solve our Stock Take mysteries.

  1. This interior shot appears to be the control room for a distribution centre – possibly Reading – but we can’t find any details in the photo that give its location away. With its brightly coloured light panels, I think it has a touch of the Bond villain’s lair about it, but perhaps that’s just me…

  1. These shots were found together and seem to be of the same rather quirky-looking building. We think it might be one of the first out-of-town sorting offices, purpose-built to house mechanised sorting equipment. Despite its unusual character, even our expert on Post Office architecture, volunteer Julian Osley, is stumped about where it might be.

  1. Similarly, we came upon these three photos together and they appear to be from the same site. Those fun-looking slides are in fact Safeglide Spiral Chutes, which are specially-designed to allow items added from different levels to work their way down at a controlled speed. We’ve had one suggestion as to where these photos may have been taken – the Parcel Concentration Office at Washington, County Durham (thank you, @RogerEvansAM!) – but any further wisdom would be appreciated.

So there we have it. If you can use your knowledge or detective skills to figure out where any of these were taken – or if you can tell us anything about their contents – please jump right in and comment below, email info@postalheritage.org.uk or tweet us!

Experiments in Photogrammetry

Recently we experimented with producing a set of 3D models of items from the collection using a process called photogrammetry. Rose Attu, a Digital Humanities MA Student from UCL, who’s currently on placement at the BPMA, talks us through the process.

To create a 3D model a series of overlapping photographs of a single object are taken from different positions, and then a piece of software is used to triangulate the coordinates of each image and align them, reconstructing the whole object in 3D. With each shot, the digital camera also records metadata including the focal distance between the lens and the object; this enables the software to recreate the position the camera was in when each photo was taken.

The objects we chose were the prosthetic Postman’s Hand and the Stamp Snake. An object covered in a repeating pattern, or one without any distinguishing features at all, will affect the software’s ability to rebuild the depth of an object. Both these objects have plenty of distinctive features, so the software could detect the details from photo to photo and build accurate models without distortions.

Our first object was the Postman’s Hand. Once it was in frame and in focus, and evenly lit to avoid shadows, we could begin the capture process. To capture our objects from multiple angles we used a turntable to rotate them through 360°. The turntable was also covered in a distinctive image, which gave the software more common points to identify. The turntable was edited out at a later stage, so that our final models were just of the hand and the stamp snake.

On average it took 30 photos to complete one rotation, after which the camera was raised for a second sequence capturing the object from a higher angle. For more consistent results we kept the camera settings the same until a rotation was complete, and used a tripod and remote shutter release to keep the camera static. We output the raw image data as a set of TIFFs and corrected the white balance, and then our images were ready to be transformed.

Based on the estimated camera positions and the details in the images, the software built a point cloud, which is essentially a 3D model made up of dots. It then added a more detailed polygonal mesh layer representing the object surface. The final step was to add the textures; because we photographed our objects in high resolution, even the tiniest details were visible on the final models.

We were surprised with how little effort and technology it took, and the results were fantastic!  For our set-up we used:

  • Lazy Susan turntable with a nonrepeating pattern on it
  • Digital SLR camera and tripod
  • Light box or tent
  • Studio lights or some source to help get rid of shadows
  • Photogrammetry software – we used Agisoft which was great and you get a 30 day free trial

Have a go yourself– we would love to see your models!

Stamps: Why the Portrait?

As an Art Historian (now Philatelic Assistant) I have always been fascinated by the portrait and a stamp in itself is a miniature piece of art. To understand why the Queen’s head appears as it does on GB stamps we need to first understand the significance of the portrait historically.

Some of the earliest profile portraits were produced by the Romans for their coins and medals.  Images of the Emperors illustrated their power and importance and thus the profile became synonymous with these characteristics. It was also a way of distributing the face of their leader, who many would never have seen.

We can see the influence of these artefacts in the work of Renaissance artists who tried to recreate this sense of power in their portraits of the wealthy. This is evident in the portrait of the Duke of Urbino and his wife by Piero della Francesca who are both depicted in profile facing one another. Yet this composition had to be used as the Duke had previously lost his right eye in a tournament. You can also see the significance of the medal in Sandro Botticelli’s ‘Portrait of a Man with a Medal of Cosimo De Medici’ c.1474-75.

However the initial portrait of Queen Elizabeth II used for postage was not in fact a profile. Instead it was a three quarter view of Her Majesty photographed by Dorothy Wilding in 1952. Though adequate as a Definitive stamp –  the Wilding design was found to be overly challenging for many stamp designers as it took up to one third of the stamp’s area and subsequently compromised the design of the stamp.

As a solution to this problem Tony Benn (Post Master General 1964-66) along with designer David Gentleman introduced the idea of removing the Queen’s head altogether. Initial ideas were produced, however in 1965 the Queen decided she wished to remain on the stamp. This led to the small profile silhouette on commemorative stamps being used instead, reminiscent of those produced in the 18th century of the English high society.

To produce a profile portrait of the Queen, The Royal Mail approached the British sculptor Arnold Machin. He took inspiration from the simplicity of the Penny Black portrait, which was based on a medal of Queen Victoria by William Wyon. This again acknowledges the historical importance of the profile.

The image of the Queen we see today is not only practical for producing stamps but also evokes the idea of power and importance, circulating her image to the nation. The significance of the portrait on a stamp is not merely a representation of the person but as a symbol of their significance. Commemorative stamps elevate the importance of an individual by allowing them to feature prominently on the stamp, though the Queen still remains dominant as the accompanying silhouette.

Two BPMA touring exhibitions open in Aberystwyth

Two of our touring exhibitions (Designs on Delivery and The Post Office in Pictures) are both on display at Aberystwyth Arts Centre starting tomorrow (18 January) until early March.

Designs on Delivery

Design played a crucial role in promoting social progress and technological change across Britain between 1930 and 1960. General Post Office (GPO) posters were commissioned in the context of specific channels of communication. Posters were designed for Post Office walls, pillar boxes and transport vehicles.

POST1103184

Post your letters before noon, Jan Lewitt and George Him, 1941 (POST 110/3184).

The exhibition posters offer a variety of visual language adopted to meet these different needs. GPO posters included work by those associated with both fine art and graphic design, demonstrating the blurring of the boundaries between high art and popular culture that poster design encouraged.

This exhibition showcases 25 of the best of these posters.

The Post Office in Pictures

The Post Office in Pictures is an exhibition showcasing a selection of inspiring images sourced from the BPMA’s vast collections.

Photography was one of the key tools used by the GPO PR Department (est. 1934) to reach and engage with the general public. In order to supply its fledgling Post Office Magazine with professionally-produced photographs, members of the GPO Photographic Unit began to accompany the magazine’s journalists.

The exhibition showcases 30 outstanding photographs from the 1930’s to the 1980’s. Also available to read alongside the exhibitions will be copies of the Post Office Magazines, from which many of these photographs are drawn.

The Post Office in Pictures and Designs on Delivery both open on Saturday 18 January at Aberystwyth Arts Centre and run until Saturday 8 March. Entry is free of charge and open to all.

Please let us know if you do visit the exhibitions, on dominique.gardner@postalheritage.org.uk, 0207 354 7287, or @postalheritage. We hope you enjoy your visit!

Behind the scenes; conservation in progress

Do you ever wonder what is happening to sticky tape? The answer is usually “No” and for a good reason. We all believe that it will remain nice and sticky for eternity! Especially nowadays when we have so many choices of self-adhesive tape or pressure sensitive tape with excellent qualities too; there are transparent, matte, colour, black, white, brown, red, archival ones, linen ones and so many more. The point is that we don’t think twice when it comes to applying it because we are confident about its short term effect and result. Well, I will try to change your mind a bit and show you how a well-intended attempt to stick together broken glass plate negatives turned into a painstaking nightmare.

In the mid-19th century, photographic negatives began to use glass as a support. Glass provided a sharper negative and a more detailed positive print, and soon replaced paper negatives. Like photographic prints, glass negatives are composite objects, consisting of a glass support, a binder, and an image-forming or recording substance. At the BPMA we store approximately 2500 glass plate negatives dated from 1930s to the 1950s with a variety of topics from day to day postal operations. 89 of them are damaged, with broken and/or missing parts. A common practice of preserving a broken glass plate negatives was to sandwich it between either one or two new glass plates and apply a tape around their perimeter to secure them. The quality and type of tape used varied but one thing was certain; the intention of the ‘restorer’ could only be described as a noble attempt to save what was broken.

Unfortunately, good intentions don’t always have the result we hoped for. So when the need arose to remove the tape, I faced a big challenge. The adhesive of the tape had permeated the emulsion layer of the glass plate negative, it had cross-linked as we say in conservation (a chemical process of bonding one polymer chain to another). This new type of bonding creates irreversible damage as it discolours and fades the image but mostly because it weakens the emulsion layer and makes it prone to flaking, putting the image at risk. Any mechanical attempt to remove it went downhill so the next idea was to use an aqueous and a chemical treatments which mean the introduction of liquid either water or solvent. I used a microscope to avoid any unnecessary contact between emulsion and water –these two things do not like each other very much.
All geared up with a microscope, a portable air extraction unit, solvent and water, apron, I have started the process of slowly moistening the tape and carefully removing it with a dentist’s spatula.

To remove tape from one glass plate negative of 80 x 100cm in dimension I have estimated it took from 14 to 20 hours. On the other hand, I have timed how long it took to apply a sticky tape on one glass plate negative mock-up of the same dimension and it took between 1-2 minutes. Pretty amazing don’t you think! Consequently in a collection of 89 damaged and taped glass plate negatives it took 3 hours to apply the tape and it would take 1780 hours to remove it, which is 254 working days! Makes you wonder why conservation sometimes can take so long!

In conclusion, I would like to emphasise to all lovely collectors out there who value and protect their collections that if you think a quick fix might solve your problem, please think twice. Besides if you are unsure about a procedure please contact a conservator who will be able to advise you and guide you to a suitable solution. In the long term, it will be a less costly and time consuming operation and it will save your precious collection for future generations to enjoy.
