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.
Expiration: The new boxed CineStill film has an extended shelf life, and should be stored in the fridge and shot within 6 months of purchase to achieve optimal results. Exposed film should be processed promptly in C-41 chemicals to preserve latent image latitude and color fidelity. All current productions of CineStill have expiration dates for two years from manufacture date on the box. If you have earlier productions of 50D (no retail box), it should be tested for base fog before use.
Note: This emulsion was originally required processing in ECN-2 motion picture processing and may still be processed using ALL of those steps, resulting in a pulled negative with lower gamma not suitable for darkroom printing. Although there is no remjet adhesive layer to contaminate and exhaust the chemicals, skipping the additional accelerant pre-bath will under-develop the film when just using the ECN-2 developer. Tests show favorable results in standard C-41 processing compared to ECN-2 motion picture lab processing performed by professional labs. C-41 processing produces greater density and gamma which is more favorable for still photography workflows. Long term archival stability has not been tested past 5 years. Expectations for archival longevity should be somewhere between Kodachrome and most C-41 films.
