Agfa · ISO 200 Color negative
Agfa Optima 200
Optima 200 replaced Agfa's older XRS 200 line in 1996 and ran until production stopped in 2005, which made it one of the last consumer color negatives the original Agfa-Gevaert plant in Leverkusen ever coated. The pitch was a finer-grain ISO 200 stock for everyday work: landscape, architecture, macro, and food photography sat in the Agfa marketing copy of the period, which gives you a fair sense of where the curve was tuned.
The technology underneath is Eye Vision, Agfa's name for a color-coupler scheme that pulled blue and green into better separation without flattening the rest of the spectrum. The silver halide crystals carry the SXM label, Surface eXtended Multistructured, which Agfa claimed improved efficiency by roughly half over the previous emulsion family. In practice the grain at ISO 200 is finer than Vista 200 of the same period and noticeably tighter than Fujicolor 200, while still falling short of Portra 160 if you scan large.
The color signature is the Agfa one. Warm reds without the orange shift of Kodak Gold, restrained yellows, slightly cooler blues than Fuji Superia 200. Skin tones come back balanced rather than flushed, which is why the film worked for editorial and amateur portrait work alike. Greens stay honest. Push past a stop and the shadows go green; pull half a stop and the negatives scan cleaner.
Latitude is solid for a consumer stock. Two stops of overexposure are forgiven; underexposure past one stop blocks faster than Portra or Reala would. C-41 is standard, no quirks.
Available historically in 35mm and 120. Production stopped in 2005 with Agfa-Gevaert's consumer film exit. Only freezer-stock and expired rolls turn up on the secondary market now, with 120 holding up better in cold storage than the smaller 135 cassettes.
Reciprocity exponent is 1.20. Zone Light Meter applies the correction past one second, so a metered 30-second exposure becomes about 60 seconds at the negative. For tripod work past the threshold on expired stock, add another half stop on top of the math.
How the app handles this stock
- Box speed: ISO 200. 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.
