Do I understand this correctly with the only difference being the type of developer used (film/paper)? When I buy paper & film, they are not the same emulsions on both surfaces, are they? If it is the case that the same liquid emulsions can produce negative and positive images, how is this possible? I need to understand which emulsion(s?) I need for the following: 1. producing negatives on glass plates exposed with a camera. 2. producing positive prints with an enlarger on glass plates. 3. for tintype images, will any of these emulsions work provided they are put on a black plate and developed with Rockland’s tintype developer?
Thank you and I am looking forward to the education & better understanding before I jump in.
