RETAIL PACKAGED 50D 120 FROM OUR NEW AND IMPROVED PRODUCTION AT CINESTILL EAST. Thanks to the support and feedback of our Film Makers, the world's finest grain color negative is coming to Medium Format! 120 format color negative, boasted to be the world’s finest grain film! CineStill 50D is an ISO 50/18° speed daylight balanced (5500K) motion picture emulsion. Technology borrowed from from Hollywood's wunderkind, Kodak 50D, prepped and rolled for safe C-41 standard development as an ISO 50 film. Our new and improved manufacturing process now extends the shelf life, with less noticeable artifacts after expiration! The same advanced motion picture emulsion, safe to process in standard C-41 photo lab machines or at home! This emulsion is optimized for a hybrid workflow, ideal for scanning, and produces a complimentary contrast curve for optical printing on RA-4 paper when processed in C-41 chemistry. Treat this film as a 50 ISO film when processing in C-41 and push process whenever needed.
