Cinestill actually say more about their film than anybody over to you team:
35mm format color negative film, factory spooled and boxed. Great rated ISO 200-2000! Can be pushed over 3000! CineStill 800Tungsten (2nd. Generation) is a unique film for still photographers. This 800 speed tungsten balanced color negative film is prepared from the same gold standard motion picture technology used by top cinematographers around the world. This film is designed for difficult low light tungsten situations and may be used in many different lighting situations to achieve a variety of looks.
Our new and improved manufacturing process now extends the shelf life to 2 years, 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 high speed 800 ISO film for C-41 processing and push process whenever needed up to 3200 ISO.
Recommended ISO and acceptable exposure for push processing:
ISO 800 - No push - EI 200-1600
ISO 1250 - 1 stop push - EI 800-2000
ISO 1600 - 2 stop push - EI 1250-3200
ISO 3200 - 3 stop push - EI 1600-3200 (added contrast)
- Color Balanced Tungsten color negative motion picture film stock for use as still photography film
- Factory spooled and boxed
- Remjet backing free, resulting in a slight halation effect
- Designed for difficult low light tungsten situations
- When shot in daylight, an 85 filter is recommended and/or shooting the film at 500 ISO
- Acceptable for push processing up to 3200 ISO
- Recommended to process C-41 without worrying about remjet
Expiration: The new boxed CineStill film has a 2 year 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 800T (no retail box), it should be tested for base fog before use.
Note: This emulsion was originally designed for in ECN-2 process and may still be processed using ALL of those steps, resulting in a 500 ISO pulled negative with lower gamma. Although there is no remjet adhesive layer to contaminate and exhaust the chemicals, skipping the additional accelerant pre-bath will under-process the film in ECN-2 developer. Test results show consistent in standard C-41 machine processing when compared with ECN-2 motion picture lab processing performed by professional labs. 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. We will replace any roll that shows defect. We do not accept any liability beyond replacement of original film purchased.
