Collodion reduced the exposure time necessary for making an image. This method became known as the 'wet-plate collodion' or 'wet collodion' method. Collodion was relatively grainless and colorless, and allowed for one of the first high-quality duplication processes, also known as negatives.
What is the difference between wet and dry collodion?
IF the collodionized plate, after sensitization in the silver bath, is exposed whilst still moist, the process by which the image is obtained, is called the Wet Collodion process; whereas if the sensitized plates are dried, and used afterward at any indefinite time, the process of the operation is denominated the Dry Collodion process.

What is collodion process?
Collodion process, mostly synonymous with the "collodion wet plate process", requires the photographic material to be coated, sensitized, exposed and developed within the span of about fifteen minutes, necessitating a portable darkroom for use in the field.
Who invented the wet collodion process?
Written By: Wet-collodion process, also called collodion process, early photographic technique invented by Englishman Frederick Scott Archer in 1851. The process involved adding a soluble iodide to a solution of collodion (cellulose nitrate) and coating a glass plate with the mixture.
How does wet plate collodion work?
It involves coating a piece of glass or metal with a collodion emulsion, sensitising it in silver nitrate and then making the picture immediately so that it can be developed before the emulsion dries (i.e. whilst it is still wet, hence the name wet plate).
What is a wet glass collodion?
The wet collodion process used a prepared piece of glass which, in the darkroom, would be coated with collodion and then made light-sensitive with further chemicals. Before the plate could dry, it would be placed in the camera and exposed.

What were the advantages of the collodion wet plate process?
The collodion process had several advantages: Being more sensitive to light than the calotype process, it reduced the exposure times drastically – to as little as two or three seconds. Because a glass base was used, the images were sharper than with a calotype.
What is collodion and where it is used?
Collodion is widely used to glue electrodes to the head for electro-encephalography. Non-flexible collodion is used in theatrical makeup for various effects. When applied to the skin, it shrinks as the solvent (usually ether or alcohol) evaporates, causing wrinkles and is used to simulate old age, or scars.
What is collodion made of?
First of all, plain USP (U.S. Pharmacopeia) Collodion is a mixture of ether, alcohol, and nitrocellulose (also known as nitrated or guncotton). It is the nitrocellulose that acts as a binder and carrier for photo-sensitive salts of silver while making wet collodion images.

Video transcript. - [voiceover] In 1851 the Englishman Frederick Scott Archer invented the wet collodion process of making negatives. This process allowed photographers to produce finely detailed images on paper and to print an unlimited number of copies. These key features were improvements over the previous two photograph processes, ...
What is the collodion in a darkroom?
The collodion enables the silver nitrate to adhere to the plate, so it is crucial that the collodion covers the entire surface. Inside the darkroom the photographer dips the plate into a bath containing silver nitrate, the chemical that will make the plate sensitive to light.

The collodion side is placed face down so that it can receive the path of light once inside the camera. Any excess silver nitrate is removed from the back.
How long does it take for a collodion to dry?
This is because collodion, the main chemical used, will dry up and lose its sensitivity after about 10 minutes. Photographers used portable darkrooms, so the plate could be developed immediately after it was shot. The wet collodion process can be broken down into a number of equally critical steps.

History
Gustave Le Gray first theorized about the collodion process, publishing a method in 1850 that was "theoretical at best", but Frederick Scott Archer was credited with the invention of the process, which he created in 1848 and published in 1851. During the subsequent decades, many photographers and experimenters refined or varied the process. By the end of the 1860s, it had almost entirely re…

Advantages
The collodion process produced a negative image on a transparent support (glass). This was an improvement over the calotype process, discovered by Henry Fox Talbot, which relied on paper negatives, and the daguerreotype, which produced a one-of-a-kind positive image and could not be replicated. The collodion process, thus combined desirable qualities of the calotype process (e…
Disadvantages
The wet collodion process had a major disadvantage. The entire process, from coating to developing, had to be done before the plate dried. This gave the photographer no more than about 10-15 minutes to complete everything. This made it inconvenient for field use, as it required a portable darkroom. The plate dripped silver nitrate solution, causing stains and potentially explosive build-up of nitrate residue in the camera and plate holders.
Search for a dry collodion process
The extreme inconvenience of exposing wet collodion in the field led to many attempts to develop a dry collodion process, which could be exposed and developed some time after coating. A large number of methods were tried, though none was ever found to be truly practical and consistent in operation. Well-known scientists such as Joseph Sidebotham, Richard Kennett, Major Russell and Frederick Charles Luther Wratten attempted, but never met with good results.
Collodion emulsion
In 1864 W. B. Bolton and B. J. Sayce published an idea for a process that would revolutionize photography. They suggested that sensitive silver salts be formed in a liquid collodion, rather than being precipitated, in-situ, on the surface of a plate. A light-sensitive plate could then be prepared by simply flowing this emulsion across the surface of a glass plate; no silver nitrate bath was required.
