The Collodion Process is a photographic technique that uses glass plates coated with a thin layer of collodion to capture images. This process was popular in the 1850s-60s, significantly improving the quality and detail of photographs compared to earlier methods. It is done through 6 steps. 

1. Pour collodion onto a glass plate

2. Insert the plate into camera while wet

3. Expose the image

4. Photo must be developed immediately after exposure

5. Fix the image

6. Wash and dry the photo to perfect it

The Collodion Wet Plate Process was invented by Frederick Scott Archer, an English sculptor and photographer, in 1851. Archer was searching for a method that could produce clearer, more detailed images than the daguerreotype or calotype processes, and his wet plate process was a huge success. This new process created sharper and detailed images, faster exposure times, and influenced many future photography methods.
