Agfa · ISO 100 Color negative
Agfa Vista 100
Agfa Vista 100 has one of the messier provenance stories in 35mm color film. The original was a true Agfa-Gevaert stock coated in Leverkusen until the parent company exited consumer film in 2005. After that, the Vista name lived on as a license held by Lupus Imaging, and the rolls in circulation were sourced first from Ferrania in Italy and then, after Ferrania shuttered in 2009, from Fujifilm. So a roll labeled Vista 100 from 2003 and one from 2014 are not the same film, and you should expect different behavior depending on what you find in a fridge.
The original Agfa emulsion leaned toward natural color rather than saturation. Greens stayed leafy rather than emerald, skies came back closer to what your eye saw than to the cyan-shift you get from Fuji consumer stocks. Compared with Kodak Gold 100 the palette was cooler and a touch flatter, which made it useful for shaded street work and overcast landscape where Gold tends to push everything warm.
Grain was tight for a budget ISO 100 film, fine enough that 8x10 enlargements held up well. It was never positioned against Ektar or Reala. Think of it as the everyday counterpart to those professional stocks: cheaper, less aggressive, with enough latitude to forgive a meter that drifts.
It is fully discontinued now and only available as freezer stock or expired rolls on the secondary market. Storage matters enormously with a film this old. A roll kept frozen since the 2000s will still look close to fresh; a roll left in a glovebox in summer will shift toward magenta and lose a stop or more of sensitivity.
Reciprocity exponent is 1.20. Zone Light Meter applies the correction past one second, so a 30-second meter reading climbs to about 60 seconds at the negative. For most Vista 100 use cases (daylight, available light interiors, the occasional tripod shot) the correction is small and predictable. Color shifts in long exposures, on the other hand, are not predictable on expired stock and bracketing is the only honest answer.
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 1.20.
- Expired film: if you load an old roll, set the expiry year and storage in the app and the ISO scales for you. Color negative decay rates are baked in.
