Andrea Quinn · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1979
Eastman Ektachrome Video News Film High Speed 7250 Tungsten (VNX) is superior color film for use in 16mm high-speed motion picture photography. VNX 7250 film features an exposure index (E.I.) of 400. This film re-quires the VNF-1 or the RVNP process and it may be forced or push-processed to an E.I. of 6400 (4 camera stops) under certain conditions. It is available for high-speed camera use in Spec. 430 (100-ft. spools) or Spec. 434 (400-ft. spools). A 16mm silent, high-speed movie film has been prepared to demonstrate the results of forced processing of underexposed high-speed camera footage featuring mechanical motion too fast to be observed by the unaided eye.
