This time around the 1830’s
is really when photography comes together.
Daguerre is in France making images with silver iodide on metal plates
and Talbot is working in England making images with silver chloride on paper.
Working simultaneously in two different countries
not quite knowing about the other.
But that changes when you start to have articles in the press.
Now it’s public
and so a rivalry begins.
William Henry Fox Talbot is a gentleman scholar in England
living in an old Abbey in the village of Lacock.
He was a member of the House of Lords.
He was a wealthy individual who had many many interests.
Talbot is on his honeymoon in Lake Como in Italy
and he’s trying to make drawings with a camera lucida.
He’s trying to do pencil sketches
and realizes he has no skill whatsoever in drawing.
He wants to make pictures within a camera obscura.
All he has to do is find the material that he can put in the back of the camera
to record the image.
Finally when he returns home to Lacock Abbey
he starts doing experiments
and he is able to produce a photographic image.
Talbot is making images by using silver chloride
in the production of making what he called photogenic drawings.
Which are essentially just coating paper with salt
coating paper with silver nitrate
and place a fern or object on top of the paper
put a piece of glass on top of that
and lay it in the sunlight, it will darken.
Up to that point it’s not so much different than what Wedgwood did.
But Niepce and Wedgwood could not figure out a way to keep the drawings.
What Talbot discovers is that if he takes that image
and puts it into a stronger solution of salt water
all the areas that were not exposed to light
all the areas that didn’t turn to metallic silver
become less sensitive.
They are not removed completely.
But he can show them to people in the house.
You can see them by candle light.
This is the type of camera Talbot used
in his earliest experiments with photogenic drawing.
Many of them are still around and you can see them
as long as you don’t bring them out into too much light.
Usually when you see them they’re under a piece of velvet
so it feels like this intimate experience
of looking at a photograph in its first days.
Now photography is so ubiquitous that we probably
don’t think about how special, and magical that experience was.
Talbot is the first person to make a salted paper print.
He actually invents something that’s permanent.
It’s basically his photogenic drawing process
that has been fixed with hypo.
Sodium thiosulfate is the modern term.
Its potential for removing silver halide
is discovered by Sir John Herschel.
Salted paper prints, because of the way they are made
where the image material sinks into the paper
tend to have a less crisp look to them.
There was this sort of dichotomy between the crisp, clean
almost three dimensional quality of the daguerreotype
and the softer, almost more granulated sensibility of the salted paper print.
So that sort of got reduced to information versus artistry
in the early years of photography’s history.
Talbot improves the photogenic drawing process
by switching from silver chloride to silver iodide.
The same silver halide that Daguerre uses in his process.
The latent image Calotype process that he invents in 1840
allows him to make a little bit of an exposure
and then he develops out the invisible image to a visible image
using gallic acid.
And so now he can put this into a camera and
actually do pictures of living human beings.
He can then make negatives and after those negatives are fixed with hypo
he can then place those on top of a second sheet of sensitive paper
expose that to light and now he makes a positive proof.
So he has negative and positive.
He essentially introduces the negative / positive potential for photography
that becomes the standard of photography
until the invention of digital photography.
The rivalry between Daguerre and Talbot continues today.
There are champions of Talbot and champions of Daguerre.
Both camps feel that their man invented photography.
In fact, it’s all photography just a different type.
After Talbot figured out this negative / positive process
he wanted to show what photography could do.
So his way to do that was to produce a series of publications
called the Pencil Of Nature.
The Pencil Of Nature contains text explaining Talbot’s process.
It contains salted paper prints
mostly showing Talbot’s home at Lacock Abbey
and each of the photographs is meant to display
one of the various uses of photography.
Talbot’s showing the reproducibility of the photograph
which really became one of the most important aspects of the medium.
