In the basement of the Silvermaster and Ullman home, Ullman maintained a photographic darkroom for copying and processing stolen documents purloined within the Silvermaster group, and reduced it to microfilm. The volume of information became so overwhelming eventually that only negatives were completed because Ullman couldn't process the stolen documents fast enough. The information was then passed on through [[Elizabeth Bentley]]. | In the basement of the Silvermaster and Ullman home, Ullman maintained a photographic darkroom for copying and processing stolen documents purloined within the Silvermaster group, and reduced it to microfilm.
