Polypan F50 is a film sourced from Polish industry, respooled and sold to film photographers. Its very high contrast sets it apart from classic B&W films — it demands mastery of development to avoid losing highlight detail. Stand development (Rodinal 1+100, 1hr) is particularly recommended to tame its contrast.
