What the Victorians did for us

Thursday, 29 September, 2016

The Victorian era was the age of invention, although the discovery of photography just pre-dates this with Niépce’s famous View from the Window at Le Gras in 1826. His early collaboration with Louis Daguerre led to the announcement of the daguerreotype in 1839 and its subsequent commercialization, alongside Talbot’s calotype. These early photos now appear very rudimentary alongside their modern film and digital counterparts, however it never ceases to amaze me with the ability of these early pioneers to push the limits of possibility. I wanted to highlight how two of these continue to have had profound impact.

Our recent fascination with 3D will most likely have come from the movies through the use of polarised glasses, although some of us may well remember using filtered red/blue glasses to view a dinosaur or shark in a kid’s magazine. However an understanding of binocular vision and exploiting this to view images in 3D (stereoscopy) goes back to Sir Charles Wheatstone in 1833 with his invention of the stereoscope.

Whilst Wheatstone used pencil drawings for his stereoscope, photography was the obvious companion for it and was immensely popular with a Victorian society eager to consume new technologies. Photographers experimented with stereo through the 1840s, however it was the Great Exhibition in 1851 that was the catalyst for its exposure to an international audience. Brian May’s (yes, that Brian May!) sumptuously illustrated photobook is a prime example (May, B. and Vidal, E. (2009) A Village Lost and Found, Frances Lincoln), showcasing T.R. Williams’ wonderful stereophotos of an undisclosed village. The book identifies the village as Hinton Waldrist in Oxfordshire, rephotographs the same scenes and includes a stereoscope (designed by Brian May). Viewing examples such as this demonstrates that there is something magical about stereo vision - it’s a window on ‘a world that was’ and we view it as if we were actually there.

The second, and at the time, unrelated technology was aerial photography. Whilst we might think of this being inextricably linked with the invention of the aircraft and its rapid development in the First World War, there had been a range of creative methods for lofting a camera off the ground. The very first aerial photo was taken by Nadar in 1858 and whilst this hasn’t survived, James Black’s 1860 photo of Boston does. It may look a little passé now, however pause for a moment to consider what was involved. The 1850s saw the dominance of the collodion wet-plate process that produced a high quality negative on a glass plate. This had to be prepared on the spot as it was light sensitive only as long as it was wet and then needed to be developed straight after exposure. That meant Black had a full darkroom in his tethered balloon that was likely swaying 365m above the Boston streets. I don’t imagine there was a detailed risk assessment completed before the trip!

Probably the most successful alternative to balloons has been kites, with the first successful photo by Batut over Labruguiere, France, in 1888. However it is George Lawrence’s photos of San Francisco in the aftermath of the 1906 earthquake and fire that are astonishing (see below). He used up to 17 large kites to lift an enormous 22kg panoramic camera (my Nikon D700 with 70-200mm lens “only” weights 2.5kg!) with a 19” focal length and 20x48” plate. This was serious kite flying!

These Victorian inventions may seem distant now that stereoscopy is a key component in movie production, something movie-goers have become very familiar with. Aerial photography is equally important in map making and, when combined with stereoscopy, allow us to extract 3D features from the landscape. Kite photography is the direct ancestor of drones, a rapidly burgeoning area. Everything that was learnt about near-Earth imaging is now being re-learnt for a new generation.
