Rare 10 packs of AGFA 100 RS film 04/1990 y.o. - original packaging, foil from the factory. Stored at 13C. The primary challenge when working with expired photographic material is chemical instability and unpredictable results. Because this lot consists of multiple rolls of the exact same emulsion stock, it allows the photographer to perform a test exposure on the first roll. By analyzing the base fog density and emulsion speed of the test roll, the exposure indexes EI can be accurately calibrated for the remaining rolls.Excellent Aesthetic Condition: The original paper boxes are mechanically undamaged, clean, and show no visual signs of degradation caused by humidity. This makes the lot highly suitable for immediate display in private collections or as an authentic historical accessory for vintage cameras.Authentic Analog Character: The emulsion of this specific stock delivers distinct grain structure, micro-contrast, and tonal rendering that cannot be exactly replicated by digital post-processing. Perfect for photographic work emphasizing the material aesthetics of the classic chemical process. Technical Condition and Terms of Sale:Important Note for Bidders:This photographic material is well past its official expiration date. Due to the natural chemical degradation of the light-sensitive layer (loss of sensitivity, increase in base fog, and color shifts depending on historical storage conditions), the film is sold strictly "as-is".The boxes are sealed and visually intact. No guarantee is provided for the final chemical results after development (Process E-6). Complaints or returns based on emulsion performance or failure are strictly excluded.
