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. 

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.
