36 exp. 135 rolls. Great rated ISO 200-2000! Can be pushed to 3000! CineStill 800Tungsten is a unique film for still photographers. This 800 speed tungsten balanced color negative film is prepared from the same motion picture film stock 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.<br><br>Our proprietary "Premoval" process makes motion picture film safe to process in standard C-41 photo lab chemicals or at home. This emulsion is optimized for a hybrid workflow ideal for scanning, and when processed in C-41 chemistry it can be optically printed on RA-4 paper. Treat this film as a high speed 800 ISO film when processing in C-41 and push process whenever needed up to 3200 ISO.<br><br><strong>Recommended ISO and acceptable exposure for push processing:</strong><br>ISO 800 - No push - EI 200-1600<br>ISO 1250 - 1 stop push - EI 800-2000<br>ISO 1600 - 2 stop push - EI 1250-3200<br>ISO 3200 - 3 stop push - EI 1600-3200 (added contrast)<br><br><em>Expiration: Unexposed CineStill film 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 one year from manufacture date on the packaging. If your film does not have an expiration date it is from early production and is likely age fogged.<br><br>Note: This film was designed to be processed in ECN-2 Chemicals and may still be processed in it's native chemistry, resulting in a 500 ISO pulled negative with lower gamma. 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 4 years. Expectations for archival longevity should be somewhere between Kodachrome and most C-41 films but there are no guarantees. We will replace any roll that shows any defect. We do not accept any liability beyond replacement of original film purchased.</em>
