Kodak Ektachrome VNF 400T 7250

VNF 7250 was the film that pulled local TV news out of the black and white era. Kodak introduced it in 1977 as the high-speed companion to the slower 7240 in the Video News Film line. ISO 400, tungsten balanced at 3200K, optimized for telecine rather than projection. The contrast ran lower than ECO or Kodachrome cinema reversal because the picture had to survive a transfer to broadcast video, not stand up on a theater screen.

Processing was VNF-1, not E-6 and not ECN-2. The acronym confused photographers who came to it from still work. VNF stood for Video News Film, and the chemistry pushed hot through machine processing in roughly 30 minutes so a stringer could shoot a fire at six and the station could cut the package by eleven. Kodak also ran a faster variant called RVNP for stations needing even quicker turnaround, though the picture quality suffered.

7250 was 16mm only. No 35mm cousin, no 8mm cut, no still-photography release. News crews shot ENG-style on 16mm Auricons and Arris before video tape eclipsed everything around 1989, and the stock was tuned for that ecosystem.

Compared with the daylight VNF 7239 in the same family, 7250 ran roughly a stop and a third faster on the published exposure index, with coarser grain and a warmer cast under mixed light. Compared with Kodachrome 40 used by hobbyist Super-8 shooters in the same era, VNF was a different animal: faster, less saturated, designed for one-pass machine processing rather than the long mailaway turnaround Kodachrome required.

Kodak discontinued the VNF line in 2004 once digital broadcast cameras had taken over. Surviving stock is freezer-only and rare. The chemistry to develop it correctly is essentially gone.

Reciprocity exponent is 1.10. Zone Light Meter applies the correction past one second. A metered six-second exposure becomes about seven and a half seconds at the negative, though in original use this film almost never saw a shutter open longer than 1/60th. If you find a sealed can at a defunct affiliate, locate a lab that can still run VNF-1 before you load it.
