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 else can I help you with?
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
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
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.
How do you make a wet plate dry faster?
If you want to dry your plate faster use a clean cloth.
What happens when silver plate gets wet?
It oxidizes. And turns green.
Is daguerreotype photography and wet-plate the same thing?
No, daguerreotype photography and wet-plate photography are not the same. The daguerreotype, invented in 1839 by Louis Daguerre, involves a silver-coated copper plate that is exposed to light and then developed with mercury vapor, producing a unique, highly detailed image. Wet-plate photography, developed in the 1850s, uses a glass plate coated with a light-sensitive emulsion that must remain wet during the exposure and development process. While both are early photographic processes, they differ significantly in materials and techniques.
A wet plate is allowed to dry o the plate rack .what happens to the water that was on the plate?
Some of the water drains to the bottom of the rack, and the rest evaporates.
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.

What will happen if one streaks a wet surface of an agar plate?
Streaking a wet surface of an agar plate can introduce excess moisture, affecting bacterial growth and potentially causing the colonies to merge or become difficult to isolate. It can also lead to the spread of contaminants and compromise experimental results.
How are volcanoes formed by convergent plate boundaries?
Where one convergent plate is subducted under another, the sinking slab (which is full of wet sediments and organic remains) is heated and some of it melts to form magmas which migrate upwards to form volcanoes on the edge of the overlying plate.
What was used as film during the Civil War to make photographs?
Glass, chemically treated (wet-plate negative) and then exposed to light was used.
