The traditional 19th century art of the wet plate collodion photographic process has interested me since I learned of it several years ago.

As the name implies, it was a wet chemical process, invented in 1851. It originally had to be done in its entirety – from preparing the chemicals and loading the camera to developing the final image after taking it - within about 10 minutes, making it incredibly impractical if you wanted to be mobile because you had to haul the entire darkroom with you.
