What challenges did photographers face when using the wet collodion process for outdoor photography?
-Photographers using the wet collodion process for outdoor photography had to carry a portable darkroom and all necessary chemicals, and they had to take the picture and develop it while the plate was still wet, which was a logistical challenge.
What is a characteristic feature of the wet collodion process visible on the glass negatives?
-A characteristic feature of the wet collodion process visible on the glass negatives is the pour marks, which are visible as waves on the negative.
How did the wet collodion process influence the democratization of photography?
-The wet collodion process, particularly through tintypes, made photography more accessible to the masses, as evidenced by the widespread use of tintypes by soldiers during the American Civil War to send images home.
How did photography change the way people remember and record history according to the script?
-Photography changed the way people remember and record history by shifting the focus from remembering through stories and poems to remembering through visual likenesses captured in photographs.
Outlines
📸 The Evolution of Portrait Photography
This paragraph delves into the historical significance of photography, particularly its impact on how people captured and remembered the likenesses of their ancestors. Initially, only the wealthy could afford painted portraits. Photography, introduced as a means to document loved ones, primarily focused on portraits. The paragraph discusses various early photographic processes including the daguerreotype, calotype, and the wet collodion process invented by Frederick Scott Archer in 1851. The wet collodion process was revolutionary as it allowed for both direct positive plates like ambrotypes and tintypes, and the creation of negatives for paper prints, thus combining the reproducibility of the positive/negative process with the detail of the daguerreotype. The wet plate process eventually replaced the daguerreotype due to its economic viability, despite the logistical challenges it posed, such as the need for a portable darkroom. The paragraph concludes by highlighting how photography has democratized portraiture and shaped cultural memory, moving away from oral traditions to visual records.
🌐 The Cultural Impact of Photography
This paragraph, although brief, emphasizes the profound cultural shift that photography has brought about. It suggests that the way we remember events and people has been transformed by the advent of photography. The paragraph implies that photography has become a primary means through which we document and recall history, moving beyond traditional narrative forms like ballads, poems, and stories to the more immediate and tangible medium of visual imagery.

Highlights
Photography initially served as a tool for the wealthy to capture their likenesses through portraits.
The daguerreotype was a popular and commercially successful early form of photography.
The calotype process introduced the concept of a negative that could be used to produce multiple prints.
The desire for a photographic process that combined the reproducibility of the calotype with the detail of the daguerreotype led to the invention of the wet collodion process.
Frederick Scott Archer's wet collodion process was a significant advancement, allowing for both negatives and direct positive plates.
The wet plate process enabled the creation of glass negatives, which could be used to produce thousands of prints.
The wet collodion process eventually replaced the daguerreotype due to its economic viability.
Photographers using the wet plate process had to carry a portable darkroom and work quickly before the plate dried.
Landscape photographers faced the challenge of carrying a wagon with all necessary chemicals for the wet plate process.
The wet collodion process left characteristic pour marks on the glass negatives, visible as wave-like patterns.
The camera used for wet collodion photography had to be large to accommodate the size of the glass negatives.
Collodion negatives could be backed with black paper or cloth to produce ambrotypes, a positive image.
Tintypes, a direct positive image on a metal plate, were one of the earliest forms of democratic photography.
During the American Civil War, tintypes became popular as soldiers had their portraits taken to send home.
The H.B. Lewis wet plate camera was typical for Civil War portrait photography, used for creating tintypes.
Photography has significantly shaped cultural memory, shifting from oral traditions to visual records.
Transcripts
Up until photography only the very wealthy
who could afford to have portraits painted
had any notion of what their ancestors looked like.
Photography was used primarily for portraits
because people is what we are primarily interested in.
We see it as a very popular way to do what we’ve always wanted to do
which is to record the features of people we love.
I’m going to show you a collodion negative on glass
very carefully.
This process was invented in 1851 by Frederick Scott Archer.
In the 1850’s you have the daguerreotype,
you had the calotype paper negative.
The daguerreotype was a commercial success.
The plate that they hand the customer is the same
plate that was in the camera.
There’s no negative.
What you got with the calotype was a negative
and it was a negative that could be reproduced very easily.
You could print dozens even hundreds
of positive prints from that negative.
But it made a very soft photograph.
It was much less sensitive than the daguerreotype.
You couldn’t do portraits easily with that process.
The desire was to have the reproducibility of a positive / negative process
with the precision and detail of the daguerreotype.
In 1851 Frederick Scott Archer invented
the process called the wet collodion process.
The wet plate process can give you a negative
to make paper prints.
It can give you a direct positive plate called an ambrotype
and another direct positive plate called a tintype.
When you do the wet plate process
you make a glass negative
and that glass negative can then be contact printed
onto various printing processes and make 1000’s and 1000’s of prints.
By the time you get to the late 1850’s it really replaces the daguerreotype.
The positive / negative process won out
in part because it was more economically viable.
It does require some advance planning when you’re taking it on the road.
You have to have a portable darkroom.
You pour the collodion on the plate, you dip it in the silver bath
and while it’s dripping wet with silver nitrate
you take the picture
you come back and develop it and
you have to do all of that before the plate dries.
And so the people who made landscape images
they had to carry a wagon with all their chemicals.
It was a challenge.
So you can see on this negative the pour marks
which are characteristic of the wet collodion process.
See this kind of wave up here that’s a pour mark
from when the photographer poured the developer onto the glass.
The camera that took this photograph would have
had to have been quite large to accommodate a negative of this size.
You could do a lot of things with collodion besides make a negative
You could back it with black paper, or black cloth
and you ended up with a positive.
These kinds of photographs, they were called ambrotypes
were generally cased and presented in the same way that daguerreotypes were.
You could expose a positive onto a metal plate
and for funny reasons these were called tintypes
even though they weren’t made on tin.
Tintypes were one of the earliest truly democratic kinds of photography.
During the American Civil War we see hundreds, thousands
of tintype images made by soldiers to send a picture home.
This is a H.B. Lewis wet plate camera
your typical civil war portrait camera.
It’s the camera that the tintypes of the soldiers would have been made from.
Photography shaped the way we remember things.
It’s a really important cultural change.
No longer through ballads and poems and stories
but through looking at a likeness is the way we remember
what happened and who was.
