As a user of collodion there seems to be some confusion of just what
collodion is. Collodion is nitrocellulose, ethyl ether and ethyl alcohol
mixture. One then "salts" it so that Silver Bromide and silver Iodide are
formed when immersed into a solution of silver nitrate. I have chatted with
a few folks who use the 'Collodion" name to mean a gelatin photosensitive
layer that they apply themselves, a la liquid light. It seems they can
generate artifacts similar to the wet plate process so they take on the name
"collodion".
Why and how anyone would want to do collodion paper is strange especially ,
in wet plate, the paper would be immersed into a silver nitrate solution and
the paper, itself, will just turn dark brown or black once exposed to light.
Perhaps they are talking of DRY PLATE Collodion on paper. The dry plate
collodion process was very insensitive. It might be good for long exposures
in the sun, but I think it is still a develop out process.
Could it be these are POP prints made with collodion negatives?
I am scratching my head looking forward to more info.
