Sorry, Ole, the Bergger "contact printing paper" is not a contact printing paper at all, although they sell it as that. Contact printing papers are silver chloride papers. The Bergger paper is not a silver chloride paper. It has silver iodide in it--the same thing film has. I have seen a fine print on it, once, and it may be a half decent paper. The older contact prints from Weston, Adams, others, were always on silver chloride paper. The only silver chloride paper remaining in production is Azo. I wish it were otherwise, but it is not.
