Founded in London by Royal Charter in 1631, the Clockmakers’ Company began assembling its collection of clocks, watches, and extraordinary objects in 1814. The Clockmakers’ Museum includes works by many of the greatest names in horology from John Harrison to George Daniels. Since 2015, The Clockmakers’ Museum has been on display at the Science Museum.
The Clockmakers’ Museum at the Science Museum.
With many delicate timepieces in The Clockmakers’ Museum, the photography team worked with its Curator, Anna Rolls, and agreed that photography would take place on the gallery for pieces too large to be easily removed from display, and in our photography studio for pieces that required customised lighting setups and handling. We also agreed to photograph everything to a white background to match the existing images of timepieces in the Clockmakers’ Museum.
The project kicked off with the longcase clocks already on display in the gallery. The team had to find inventive solutions to a few challenges this posed: the gallery’s layout meant some clocks were close to each other, which made manoeuvring and setting-up equipment a challenge. Also there were many reflections from nearby objects – clocks and watches are often made up of highly reflective materials such as glass or metals – a challenge to be overcome. While post-processing (editing photographs after they have been taken) can solve many undesirable reflection issues, the team tried to compensate for these issues at the time while ensuring accurate images were still captured efficiently.
Most issues were resolved by combining several images into one final photograph. We used specialist camera lenses to bypass the challenged of other showcases nearby, and unwanted reflections and shadows were corrected with the use of white cards and translucent panels, as you can see below in the process of capturing the astronomical longcase clock by Roland Jarvis.
Roland Jarvis was an artist based in Hastings, England, who also had an interest in engineering, and took up clockmaking when he was in his forties. This complicated clock has a modern design whilst still retaining the proportions and elegance of a traditional clock. It also has a whole host of complications – features beyond basic time telling – like the time of sunrise and sunset, the position of the sun and moon relative to the zodiac, and even features a planetarium.
Finally, all images were carefully separated from the original setting in the post-production and placed on pure white background (see images below).
For the photography in our studio, we used the focus stacking technique, which means capturing multiple images with varying depths of field and combining them in a ‘stack’ for perfect front-to-back focus. As the team carried out this photography, we noticed a link between the object’s size and the number of images in a focus stack: the smaller the object was, the more photographs needed to be taken to achieve the perfect image – as many as 120 per watch!
Our final way of working consisted of several stages. The base lighting had to be a soft and even, particularly for highly reflective timepieces. The team used light tents and translucent panels (which you can see all around the photographer in the image below) to avoid reflections of the studio and equipment in use.
While soft lights were better for minimising shadows and reflections on the object, harder and more focused lights were introduced for accentuating details. We controlled flare and light spread to reach the level of light intensity needed for each photograph.
The shape and texture of the timepieces varied greatly. By adding an additional light directly from the side, we were able to emphasize the texture, especially on watches with engravings and fine relief. You can see this in the images below of this 17th century French watch: the first two (left and centre) show the difference between soft and side light with the final and the third image (right) showing the final result, when the two images were combined in post-production.
Watch in an octagonal silver case by Robert Grebauval.
Once the setup was fully customised, a sequence of images was taken in quick succession as seen in the image below. We then use specialist software to group all images of the same object (seen on the left screen) and process the images to achieve perfect focus throughout the image to bring out all the delicate details of this pocket watch.
The early 1600s saw a rise in the number of watches produced in Europe, like the one pictured above. As they were not the best timekeepers, so their design concentrated on form and decoration. This type of watch was hung from a cord, around the neck or tied to the waist, and could be octagonal or oval in shape. The technique of engraving was often used to decorate the dial and case. This involved the use of a sharp tool to cut grooves into the surface metal. These lines and grooves would catch the light differently to the top surface, allowing an image to appear. This makes it a beautiful object to look at in person – but particularly tricky to capture all the engraved surfaces on camera.
Once the final image was created, the background was carefully cut out and corrected to pure white, with about 40% of the original shadow recovered to visually ground each subject.
Working on this project has helped us change the procedures we use to capture photographs. We now have several thoroughly tested lighting setups for objects made from reflective materials, which lead to consistent high quality results. We also now use focus stacking as our standard practice when working with small objects.
You can see more of the new images we have captured on our website.
Visitors to the Clockmakers Museum can now try four new interactive clockwork mechanisms which show some of the many ways clockwork mechanisms can also create sound and make things move, using gears, cams and levers.
One of the world’s most valuable watches is also currently on display in Versailles: Science and Splendour. Named ‘Marie Antoinette’ after the queen who was meant to wear it, the No.160 watch by Abraham-Louis Breguet is made of exquisite precious materials and represents the pinnacle of artistic ingenuity and intricate engineering. This stunning watch is on display until Monday 21 April. Book tickets here.

“I mean, photography is alright if you don’t mind looking at the world from the point of view of a paralysed Cyclops – for a split second. But that’s not what it’s like to live in the world.”
– David Hockney
You’d be forgiven for thinking that David Hockney doesn’t like photography very much. Bradford’s most famous visual artist has had some choice things to say about photography’s limitations over the years, and yet he has dedicated many, many hours to creating stunning works of photographic art.
Hockney’s photo-collages, or ‘joiners’, are some of his most recognisable artworks – huge scenes made up of dozens of overlapping photographs, like this portrait of his mother, Laura, perched on a tombstone at Bolton Abbey.
Hockney developed his joiner method in direct response to what he saw as photography’s biggest failing: its inability to reflect the complexity of how we really see the world around us. As he explained in a 1983 episode of The South Bank Show, he became frustrated with only being able to capture “frozen moments” with a camera – split seconds of action, leached of life.
“I’d become very, very aware of this frozen moment that was very unreal to me. The photographs didn’t really have life in the way a drawing or painting did, and I realised it couldn’t because of what it is. Compared to Rembrandt looking at himself for hours and hours and scrutinising his face and putting all these hours into the picture that you’re going to look at – naturally there’s many more hours there than even you can give it. A photograph is the other way round. It’s a fraction of a second, frozen, so the moment you’ve looked at it for even four seconds, you’re looking at it for far more than the camera did. And it dawned on me that this was visible, and the more you become aware of it the more this is a terrible weakness. Drawings and paintings do not have this.”
Hockney’s joiners were his antidote to the frozen moment, a way of imbuing his photography with action and a sense of time passing. An excellent example is one of the gems of our collection, currently on display in our temporary exhibition David Hockney: Pieced Together.
‘Bradford, Yorkshire, July 18th, 19th, 20th 1985’ by David Hockney, on display in David Hockney: Pieced Together, National Science and Media Museum, 2025
In the summer of 1985, Hockney made Bradford, Yorkshire, July 18th, 19th, 20th 1985, a joiner of this very museum, then called the National Museum of Photography, Film and Television. He took dozens of photographs from the top of a platform lift, attracting the attention of museum staff, passers-by and people working on the roof of the Alhambra theatre behind him. He then sent the film to a local photo shop to be printed, before stretching out on the floor of a museum office to put the joiner together.
Hockney took the joiner photographs in horizontal lines from left to right, moving the camera a little bit between shots. You can tell the direction he moved in because the same woman wearing a beige jacket appears several times as she walks past the museum, something that Hockney could only have caught by following her path with his camera.
A detail from Hockney’s joiner of the museum. Science Museum Group.
In his 1983 interview for The South Bank Show, Hockney explains that the sense of time passing in his joiners “is not an illusion. It is real and accounted for in the number of pictures. You know it took time to take them, wait for them [to be printed], put them down and so on.” The woman in a beige jacket is a clear example of this phenomenon at work. Because we see the same person repeatedly, we know that it took Hockney as long to take those photos as it did for her to walk by. Similarly, faster-moving vehicles are fractured across several photographs as Hockney tried to snap them before they sped past. In short, we can see the time Hockney spent taking the photographs in the photographs themselves.
A detail from Hockney’s joiner of the museum. Science Museum Group.
While true for all his joiners, Hockney’s notion of being able to see the time it took “to take them, wait for them, [and] put them down” is even more relevant to the photographs in this particular joiner.
Unlike today’s digital cameras, film cameras had no preview screen or way of scrolling through the images already taken – Hockney had to rely on his memory of what he had already photographed when lining up his next shot. It was only once the photographs were printed and the joiner assembled that the overlaps and relationship between the images became clear. When assembling the museum joiner, Hockney discovered a problem – he didn’t have enough photographs to complete the scene. He went up the platform lift again the next day, took some extra photographs, and sent the film to Clear Colour Processing, a shop in the Kirkgate Shopping Centre which offered one-hour printing. The original processing envelope has ‘URGENT’ scrawled at the top, along with a note of the 35 extra photos he took.
Clear Colour Processing envelope on display in David Hockney: Pieced Together, National Science and Media Museum, 2025
Hockney then incorporated the extra prints into the joiner alongside the ones he had already taken. This is why there are three dates in the joiner’s full title – the first set of photographs were taken on the 18th of July, he began assembling the joiner on the 19th, and the last batch of images was taken and the joiner completed on the 20th.
When you look closely at the joiner, there are clues that the photographs were taken on two separate days. The sky is overcast on the left while the sun is shining on the right, and in some pictures the pavement is wet, but dry on the rest.
A detail from Hockney’s joiner of the museum. Science Museum Group.
One set of photographs is also more matt in appearance because the two different printing shops Hockney visited used different paper (you can see in the image below that the photo with the section of blue sky is much shinier).
A detail from Hockney’s joiner of the museum. Science Museum Group.
As well as revealing the passing of time through the obvious work and attention that went into creating them, joiners manipulate time in the way they encourage us to look at them.
When we look at the real world, we move our eyes and bodies to scan our surroundings and focus on the things that interest us. It takes time and events change in front of our eyes. It is this real-life experience of viewing a scene that Hockney tries to replicate when we look at his joiners, using different arrangements of images to capture our attention for different amounts of time.
For example, in the museum joiner, we’ve already seen how Hockney catches half a car as it moves quickly past the camera. In contrast, he includes multiple photographs of the same bystanders to show how their positions and facial expressions change over the course of a conversation. Not only do we know that the two events would have happened over different lengths of time (fast car, long chats), but we are likely to spend more time looking at the photographs of the people than the car, if only because there are more individual images to scan and make sense of.

Looking at a Hockney joiner is a lot like sitting on a bench and watching the world go by. You can sit back and let the busyness of the whole scene wash over you, or you can lean in and get lost in all the details. Either way, it’s time well spent.
