The Wet Collodion process was invented in 1851 by an Englishman named Frederick Scott Archer. It was an answer to Talbot's paper negative, the Calotype (1839), and the Daguerreotype (1839) from Louis Daguerre (a silver coated copper plate fumed with iodine and bromine and developed over hot Mercury). The paper negative printed on Salt paper was "soft" but reproducible and the Daguerreotype was sharp and highly detailed, but it was a "one-off" and not reproducible. The Wet Collodion process produced a sharp, highly detailed negative and it was also reproducible - printed on Albumen and Salt paper.
The steps of making a Wet Collodion image:
1. Cut a piece of glass and de-burr or de-sharpen the edges
2. Clean the glass very well.
3. Flow Collodion onto the plate (this Collodion contains two salts; an iodide and bromide. It also has additional alcohol and ether.
4. Sensitize the plate in silver nitrate for 3 - 5 minutes.
5. Expose the plate in the camera.
6. Develop the plate with an iron base developer - this developer contains distilled water, alcohol, acetic acid and iron.
7. Fix the image in KCN or Sodium Thiosulfate.
8. Varnish the image with Gum Sandarac, alcohol and lavender oil.
9. Let the varnish cure and et voile! A Wet Plate Collodion image.
Post Script: The Wet Collodion process can produce both Negatives and Direct Positives. The process is basically the same.

What is the wet plate procces by frederick scott archer?
the collodion was carefully poured onto a perfectly clean glass plate. when the ether had almost evaporated, the plate was plunged into a bath of silver nitrate to sensitise it. the still wet plate was put in a plate holder and was exposed in the camera. after the exposure the plate was developed fixed and washed.

What is the exposure time for wet glass collodion?
100000 hours
What is the difference between a wet plate camera and a dry plate camera?
A plate camera exposes to focussed light a glass plate coated with a solution of silver salts. In the early days the formula for the solution was such that the coating had to be fresh - not necessarily actually wet (which would have run and made some weird effects) but absolutely new. Fox-Talbot and his emulators travelled with a darkroom tent and coated their plates on site. Once the chemical process had been refined, it became possible to coat plates at home and take them out in a light-proof box because the coating remained active for much longer - days instead of minutes. celluloid film came much later. People who need immense detail in their pictures still use glass plates, but wet plates, unless somebody wants to try the process for fun, are long gone. The statement about the wet plate process is not accurate. I am a modern wet plate artist. The process is called WET PLATE COLLODION because the Collodion HAS TO STAY WET for the proces to work,if it's not wet, it looses sensitivity and will not produce an image.

Who improved the camera?
First photo-1827 Joseph Nicephore Niépce produces the first successful picture over an eight hour exposure time. 1837 Daguerretype In 1837 Daguerre creates his first Photo on a copper plate coated with iodide of silver. 1840 Calotype Talbot sensitized paper to light with a silver salt solution. He then exposed the paper to light. In 1851, Frederick Scoff Archer,Glass Negatives & The Collodion Wet Plate. Ambrotype - 1850s a faster and less expensive photographic process. The tintype photography process was patented in 1856 by Hamilton Smith. 1879- wet plate photography,Frederick scott archer. 1861 -The first color photograph taken by photographer Thomas Sutton. Maxwell discovered that color photographs could be formed using red, green, and blue filters. 1871- dry plate photography English Inventor RL Maddox, seeking to develop a less cumbersome process than the wet-plate collodion method, experiments successfully with silver bromide and gelatin to produce a dry plate.
What is dry film?
Dry film is what they sell now, and it's a really great invention--it more than anything opened photography to the masses.The other kind of film--well, plates back then--was wet film. How it worked was wild indeed: When you went to photograph something, you brought your darkroom with you. When you found the thing you wanted to photograph, you went into your darkroom, coated a glass plate with "collodion"-based emulsion, put the plate in your camera, took the photo and developed it all before the emulsion had a chance to dry. If the emulsion dried before you developed the picture, it wouldn't come out right. And because collodion is flammable--it's dissolved in a mixture of alcohol and ether--photography was hazardous.
A wet plate is allowed to dry on the plate rack what happens to the water that was on the plate?
Some of it will drip of and some of it will evaporate
What are the use of salicylic acid camphor and castor oil in the preparation of collodion?
they act as plasticizers, resulting in a flexible collodion after the more volatile solvents evaporate
Why should you unmould the dessert on a wet plate?
Not all desserts need to be unmolded on a wet plate. If the dessert is made with something that will stick to the plate, such as a European jelly dessert, then wetting the plate first will help keep it from sticking to the plate.
Why do you turn mousse over on a wet plate?
Because it sticks to the wet surface and detracts it from the mould
Early camera plates were covered with what material?
Collodion
How do you make a wet plate dry faster?
If you want to dry your plate faster use a clean cloth.
