These are test shots from ORWO UN54 100ASA from Filmotech, Wolfen. I bought this film in a roll 400feet. That was the smallest dimension I could buy. Recently, they are also selling 100feet rolls. I had kept this in a freezer at home for a suitable day when I could re-roll the film in cassettes in the dark. However, my refrigerator had a short circuit and the freezer was full of vinyl chloride vapors and soot, when I opened it last fortnight. Either the chloride vapors or the heat baked the plastic cassettes and the inner plastic lining of the freezer out of shape and warped them all. All my films in retail packs were de-sensitized. Luckily, the ORWO metal-can seems to have protected the big roll. Last night I re-rolled about a 100feet into my loader and then on to a cassette. Loaded the cassette in my Praktica Nova IB with Oreston and took a few test shots this morning. This film is made on a base [Mylar, possibly, or equivalent] thicker than all the retail B&W cassettes I have seen. Loads firmly in the scanner. The emulsion seems to have more depth; those are the first impressions. May find something more. Here are some samples.
