You are probably right, jrong. I had seen the name Agfa Scala in photo magazine mail order ads, but I never paid any attention until I saw the slides at the architectural lecture. When I heard that special mail- in processing is required I lost interest. I can't think of any reason to use Scala in LF unless I wanted to publish b&w photos. There are excellent negative films available that we can process ourselves + or - to our personal requirements.
