Fujifilm Velvia 100F
Velvia 100F existed for roughly one product cycle, bridging the gap between the tripod-dependent Velvia 50 and the later Velvia 100 that replaced it. The F stood for Fast, Fujifilm's shorthand for the one-stop advantage over the original. It was the Velvia that working assignment photographers could actually use without a tripod bolted to a tripod head.
The saturation is lower than Velvia 50. Not dramatically lower, but enough that a direct comparison on a light table shows the 50 as louder. The 100F sits between Provia 100F and Velvia 50 in the saturation hierarchy. For travel and editorial work where the editors wanted some Velvia character but the shooting conditions did not permit a tripod, the 100F was the practical option. Handheld at f/4 in open shade at 1/125 is a very different situation than a locked-down tripod frame on a calm morning.
Contrast is high, latitude is narrow, same general story as the other Velvia variants. Place the highlight with care, expose accurately, bracket when you can. The film does not reward sloppy metering.
The reciprocity exponent is 1.10, steeper than Velvia 100 which replaced it. For long exposures, Zone Light Meter adds the correction past one second, and at 1.10 the additions are meaningful: a metered eight seconds extends to about nine and a half at the negative. The 100F also shows the shadow-to-magenta color crossover behavior at longer exposures, consistent with the Velvia family generally.
Fujifilm introduced Velvia 100 in 2005 as a successor to the briefly discontinued original Velvia, and the two slower stocks ran alongside each other for years. Velvia 100F itself was discontinued in 35mm, 120, and 4x5 in 2012, with only the 8x10 sheet surviving in Japan. Among photographers who shot both, opinion was split: 100F kept the lower-saturation editorial profile while Velvia 100 leaned closer to the original Velvia look. The 100F is a historical footnote now, though rolls occasionally surface in old refrigerators and estate sales. Treat frozen old stock with caution on anything where color accuracy matters.
How the app handles this stock
- Box speed: ISO 100. Picker exposes pull/push chips so you can shoot it at any speed you want and the meter follows.
- Reciprocity: Above one second the app raises metered time to the power of 1.10.
- Expired film: if you load an old roll, set the expiry year and storage in the app and the ISO scales for you. Slide decay rates are baked in.
