At 18,600 Feet With a Camera: How Samuel Bourne Photographed the Himalayas in 1866

Samuel Bourne was a young Englishman from Nottingham who arrived in India in 1863 with a camera and chemicals. He hoped photography would provide a living. In Simla, he joined Charles Shepherd in a studio that became Bourne and Shepherd, selling views to officials, officers and travellers. His work mattered because few people had seen the Himalayas in photographs.

Between 1863 and 1866, Bourne made three expeditions from Simla. He travelled through Kinnaur, Kashmir and Spiti on foot and horseback. In 1866, near the Manirang Pass in Spiti, he photographed at roughly 18,600 feet. He carried cameras, glass plates, chemicals and a portable darkroom tent with help from many porters.

That achievement showed how far early photography could be taken. The fragile plates had to be prepared, exposed and developed quickly, even in thin air and fading light. Bourne printed the negatives as albumen prints, and his images survived as an early visual record of Himalayan ridges, valleys, rivers and snow.

The wet collodion process was an early photographic method using a glass plate coated with collodion. Bourne sensitised that coating in silver nitrate, placed the plate in his camera, exposed it, and then developed it. The process produced a negative that could later be printed. It allowed detailed photographs, but it demanded careful timing and preparation in the field.

The plate had to remain wet through the exposure and development stages. The article states that Bourne completed the sequence within ten minutes before the coating dried. Therefore, he could not simply prepare a large supply of plates at home and develop them much later. Every photograph required a working darkroom close to the camera.

This constraint shaped the expeditions. Bourne carried a portable darkroom tent, glass plates, silver nitrate and other chemicals across steep Himalayan routes. The process made each image a timed field operation. It also explains why local porters and guides were essential to keeping the fragile equipment moving.

The Manirang Pass location stood at roughly 18,600 feet in the Spiti region. Bourne photographed there during his 1866 expedition, the third of three Himalayan journeys made from Simla between 1863 and 1866. The figure gives a sense of the extreme height involved, even though the work was done with nineteenth-century equipment.

The altitude was remarkable because it is believed to have been among the highest places anyone had then taken a camera. Bourne was not carrying a light modern device. His kit included cameras, glass plates, chemicals and a portable darkroom tent. The plates could measure up to 12 by 10 inches, adding weight and fragility.

The achievement also depended on a large support team. Dozens of porters hauled supplies over passes and rivers, while local guides helped the caravan move along steep tracks. At high altitude, Bourne worked with thin air, fading light and a wet process that demanded rapid development. His photographs therefore recorded both a landscape and a difficult technical expedition.

Bourne’s expeditions needed a complete temporary photographic workshop, not just a camera. He carried cameras, glass plates up to 12 by 10 inches, chemicals and a portable darkroom tent. The equipment mattered because wet collodion plates had to be coated, sensitised, exposed and developed in the field.

The supplies were heavy and delicate. The plates were made of glass, so they could break on steep tracks or during river crossings. The chemicals were also essential, especially silver nitrate for sensitising the collodion coating. Dozens of porters hauled the entire load over Himalayan passes and rivers while Bourne travelled on foot and horseback.

This arrangement allowed Bourne to make photographs far from a permanent studio. It also shows that the expedition was a group effort. The tent provided the working space needed to process each plate within about ten minutes. Without the equipment, supplies and people moving them, Bourne could not have built his collection of mountain views.

The limitations of 1860s plates changed what viewers saw in Bourne’s Himalayan photographs. The plates responded mostly to blue and violet light rather than recording all visible colors equally. As a result, the tonal information in the sky was weak or missing when the negative was printed.

The article states that skies often appeared as blank white areas and clouds vanished. This meant Bourne’s views could not rely on dramatic cloud formations or richly detailed skies. Instead, many compositions directed attention toward solid landscape forms: ridges, valleys, rivers and snow. The missing sky became part of the images’ visual character.

This limitation also shows that photographs are shaped by their tools. Bourne’s pictures were not simple, complete copies of what he saw. The wet collodion process, the plates’ light sensitivity and the printing method all affected the final appearance. Even so, the images gave buyers in India and Britain views of Himalayan terrain years before mass travel made those places widely familiar.

The local porters and guides came from hill villages near the routes Bourne travelled. They were part of the working caravan that made the expeditions possible. Porters carried cameras, chemicals, glass plates and the portable darkroom, while guides helped keep the group moving through difficult mountain terrain.

Their importance is clear from the wet collodion process. Plates had to be prepared, exposed and developed quickly, so Bourne needed his supplies close at hand. The equipment was heavy and fragile. The article describes porters hauling it over steep tracks, passes and rivers. Guides supported movement through regions including Kinnaur, Kashmir and Spiti.

Few of these workers’ names survive, but their contribution is built into every exposure. Bourne could not have photographed near the Manirang Pass or assembled his Himalayan collection alone. Their labour connected the technical act of making a photograph with the practical work of reaching remote landscapes. The surviving images therefore preserve an achievement shared by Bourne and the people who supported him.

A photographic plate creates an image by allowing light from a scene to act on a light-sensitive coating. Bright and dark parts affect the coating differently during exposure. Development then reveals those differences as a photographic negative, which can be printed. In Bourne’s wet collodion process, the glass plate was coated with collodion and sensitised in silver nitrate before entering the camera.

The plate’s sensitivity determines which parts of the scene leave strong information. Bourne’s plates responded mostly to blue and violet light. Blue skies therefore affected the plate strongly and could become pale or blank when printed. Clouds often differed too little from the surrounding sky in the recorded light, so they disappeared. The final image emphasized landforms instead.

That is why Bourne’s photographs often focus on ridges, valleys, rivers and snow rather than sky. The result was not simply a choice of scenery. It reflected the interaction between Himalayan light and the chemical limits of the plates. Those images still survive after 163 years, preserving views shaped by that early technology.
