Agfa · ISO 400 Color negative
Agfa Optima 400
Optima 400 belongs to a family Agfa marketed in two waves. The earlier rolls carried the plain Optima name; the later professional version sold as Optima Prestige II 400 after Agfa folded their Eye Vision color technology into the line around 2002. Eye Vision had debuted in Vista and Futura II in 2000, and the Prestige tier pulled it upward, with finer grain and tighter color separation than the consumer Vista 400 ever managed.
The palette is what people remember. Agfa color stocks have always rendered reds with a particular warmth, less orange than Kodak Gold and less pink than Fuji Superia. Optima 400 leaned into that. Skin tones came back with a flushed quality that flattered cool northern light, which is part of why German wedding shooters bought it through the late 1990s when Portra was still finding its identity. Compared with Fuji NPH 400, Optima 400 trades a small amount of resolution for warmer mid-tones and slightly louder yellows.
Latitude is decent but not Portra-grade. A stop of overexposure prints fine. Two stops under and the shadows go muddy with a green tinge that scanners struggle to neutralize. Rate it at 320 if your rolls are within a few years of their date code. For seriously aged stock, drop another half stop and scan flat.
Production ended in 2005 when AgfaPhoto entered insolvency in Leverkusen. The film was sold in 35mm, 120, and 220, with 120 being the format most worth chasing on eBay today since it survives cold storage better than the smaller cassettes. Process is C-41, no quirks.
Reciprocity exponent is 1.20. Zone Light Meter folds the correction in past one second on the standard curve, so a 30-second meter reading climbs to about 60 seconds at the negative. On expired stock the curve drifts further, and you may want to add another half stop on top of the math for indoor work past about ten seconds.
How the app handles this stock
- Box speed: ISO 400. 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.
