A First-Timer’s Foray Into Wet-Plate Photography
And why tintypes are the opposite
The 19th-century technique of wet-plate collodion photography, and the tintype process in item, is undergoing something of a renaissance at the moment as digital photography prompts people to explore older analogue methods. Check out Joni Sternback’s tintypes images of surfers, for case, or Victoria Will’s tintype portraits of movie stars, taken at the Sundance Festival.
I’thou interested in Victorian applied science, so I wanted to give it a try. And then did my wife Kirstin, for a rather different reason: she has been shooting a lot of film lately, and enjoys the fashion its physical limitations forcefulness her to put much more thought into each paradigm.
So the chance to spend two days doing photography using 150-twelvemonth-quondam techniques appealed to united states of america both, because it’s pretty much the oldest and near fiddly kind of photography there is. In an historic period when photography has never been easier or quicker, we wanted to see what information technology was similar when it was hard and boring.
Fortunately, there are people out there who volition show y’all how to do it, even if yous’ve never been near a darkroom before. Our tutor for the weekend was John Brewer, who holds regular workshops in Manchester and London. The grade was hosted past the Double Negative Darkroom, based in E London, not far from where we live.
The 7 people on the course (including the 2 of us) all had dissimilar reasons for wanting to explore this old technique: for personal projects, to teach it to others, to try something new or to experience photography in its original, primitive form.
John began by telling u.s.a. the history of the moisture-plate collodion process, which was the dominant process from the 1850s to the 1880s. Along the way, John repeatedly emphasised only how dangerous information technology was to mix the chemicals yourself. It turns out that yous can quite easily create explosives by blow, and deadly poisonous cyanide gas. Fortunately John had mixed everything for us in advance, which greatly reduced the risk and complexity. (We wanted information technology to be difficult, but not
hard.) He also explained how to operate the old cameras and lenses we were using, many of which were themselves antiques. And then he did a glass-plate test shot (of Kirstin and me, as information technology happens) to show united states of america how the process worked in practice.
The wet-plate collodion process involves a huge number of manual steps: cutting the glass or metal plate; wiping egg-white along its edges; coating it evenly with a syrupy substance chosen collodion; making it light-sensitive by dunking it in argent nitrate for a few minutes; loading the wet plate carefully into a “nighttime slide” which is inserted into the camera; taking the picture; then developing it, which is rather similar processing a black-and-white print.
You lot take most 15 minutes to betrayal and process the wet plate earlier it dries out. This is why photographers in the 19th century had to take chemistry labs with them everywhere, in blackness tents. There are a lot of steps, in short, and a lot of things to go wrong. And information technology was even harder and more than unsafe without modern chemicals. We speedily came to appreciate just how amazing information technology was that people managed to photo anything at all.
For each prototype, we set up upward the shot nosotros wanted first, so we wouldn’t waste product valuable time composing and focusing. And then nosotros went into the darkroom to make the wet plate.
On the first twenty-four hours we all made images on drinking glass, and on the second mean solar day we used aluminium (images on metal plates are called tintypes, though nobody actually uses tin can). Next nosotros went exterior to expose the plate. This procedure has an effective ISO/ASA of less than i, so information technology requires long exposures, typically of between four and 11 seconds. You can’t employ a light meter, because moisture plates are sensitive to a different range of the visible spectrum. And so John had to guess the initial exposures for the states as a starting point, and we all adjusted as nosotros went along. The exposures are so long that cameras of the period exercise non need shutters. Instead, we could just put a bowler hat over the end of the lens, remove it for the exposure, so put information technology dorsum again.
So we rushed back inside to develop the paradigm under a red light in the darkroom. This involves pouring a tiny loving cup of developer over the plate and so that it is entirely covered, which is more hard than you might think. Once the image has appeared in negative, water is used to cease the process, and the plate is then dropped into a set bath, which causes it to turn, magically, into a positive prototype. It’south the fix bath that can produce cyanide fumes if you go things wrong.
Finally, the paradigm goes into a h2o bath to be washed. When the plate is dry out, there’due south another opportunity to mess things up: coating the prototype with lavender oil, which again must be poured by manus to make an fifty-fifty glaze, and only when the plate has been heated up just the right amount, from below, with a hair dryer. Information technology smells lovely, though.
Each of usa made several images. A few of the plates came out perfectly, but nigh of them went wrong in i way or another, and we were all able to learn from each other’due south mistakes. It didn’t thing that things went wrong, and some of the mistakes looked really arty, like my commencement glass-plate image of Kirstin. Y’all tin can tell that I didn’t fully glaze the plate with collodion, which is why in that location’s a bare area at the bottom right. Balancing the plate on your fingertips, pouring liquid over it and tilting it advisedly to ensure an fifty-fifty glaze is a skill that takes much longer than a weekend to master.
We all came abroad from the course impressed by but how difficult photography used to be. At the aforementioned time, back then information technology must have seemed like magic, so you can see why people were prepared to make all that try. And when you run into a picture that has been taken outdoors, it’s astonishing to think how much equipment had to be carried around.
Given the immediacy of the process, nosotros were tempted to liken information technology to a kind of Victorian Instagram. Just we had the darkroom nearby and everything mixed and prepare to go, which fabricated it relatively quick and easy. For practitioners at the time, moisture-plate photography, with its inconvenience and lack of portability, would have been far more laborious. There is however some other analogy between the wet-plate era and modern photography — 1 that holds a lesson for us today.
The Google Drinking glass of the 1870s
Wet-plate collodion was displaced almost overnight past the advent of dry-plate photography in the late 1870s. Of a sudden there was no demand to carry chemicals effectually: companies sprang upward to make dry plates, which were much more convenient to handle and far more than sensitive than wet plates, allowing for faster exposures. For the outset time information technology was possible to take a photographic camera anywhere and snap an image without a tripod, and without asking permission. The combination of dry plates and affordable cameras from Kodak and other manufacturers democratised photography, an activity which was rapidly embraced by an ground forces of enthusiastic amateurs.
The snapshot craze caused an immediate backlash as people objected to existence “Kodaked” by “camera fiends.” They were worried that photography constituted an invasion of personal privacy, and that it might exist used to capture images of people in compromising situations without their permission (for case, when wearing swimwear).
In 1884, under the headline “The Camera Epidemic”, the
New York Times
likened the spread of cameras to an outbreak of cholera. “Photography affords a very prissy pastime to certain people, but the multiplication of instantaneous cameras has become a perfect nuisance to the general public,” ane homo complained to his local newspaper. (This episode is brilliantly described by Bill Jay, a historian of photography, in his 1986 essay “The Photographic camera Fiend”.)
The parallel with modern worries virtually smartphones and habiliment cameras like Google Glass, which allow photographs to exist taken anywhere, fifty-fifty surreptitiously, is striking. Efforts to ban snapshot cameras failed, except in Germany, which introduced a constabulary banning photography without permission in 1907. Instead, new social norms arose to govern the use of snapshot cameras.
Today nosotros are nonetheless in the process of negotiating the finer points of the etiquette of smartphone photography — is it acceptable for the president of the United states of america to shoot a selfie at a memorial service? — but it is now generally accepted. Arguments over the apply of wearable cameras are at an earlier stage. But the history of dry-plate photography suggests that initial outrage will requite way to eventual acceptance, provided the broader benefits (and not merely the drawbacks) of the new technology become apparent.
Going through the laborious procedure of wet-plate photography provides an obvious contrast with digital photography, but it likewise offers some sense of the convulsion that the advent of dry-plate photography must have caused. We’re used to thinking of photography as being divided into analogue and digital eras, but the transition from long exposures with giant cameras to snapshots with pocket cameras was arguably just every bit meaning. That’s why the alchemical procedure of wet-plate photography is equally far from digital photography as it is possible to get: in both respects, moisture-plate photography is the opposite of Instagram. And that contrast explains why it is attracting so much renewed interest today.
