Forte Pan 200

B&W negative ISO 200 Discontinued cubic-grain · hungarian · mid-century-look

Fortepan 200 sat in the middle of the Forte B&W lineup, between the 100 and the 400, coated in Vac through the late 1990s and into the early 2000s. After Forte filed for bankruptcy in 2004 a handful of distributors kept rebadging it for a few more years. Production stopped for good in January 2007. What you see on the secondhand market now is exclusively freezer stock and expired rolls, most dating from 1995 onward.

The emulsion is traditional cubic-grain silver halide, not tabular. At box speed the grain is more pronounced than HP5+, with a tonal curve that runs slightly contrastier through the midtones. Reviewers who tested fresh Fortepan 200 in HC-110 dilution B reported clean negatives at around 7 to 8 minutes of development; expired stock typically wants exposure compensation of one to two stops down toward EI 100 or EI 50, depending on storage history.

Compared with HP5+, Fortepan 200 sits a stop slower nominally but pushes less gracefully, and the highlight roll-off is sharper. Foma 200 is the closest current peer; Forte tends to come back a touch cleaner with less base fog, though the difference narrows on heavily aged stock. The film curls badly after years in storage, sometimes severely enough to launch itself out of a developing reel during loading. Bring patience.

Where it earned its reputation is in the look. Tonal rendering on a well-exposed Fortepan 200 negative has a creamy midtone signature with structured grain that reads as genuinely mid-century European rather than a digital simulation of one.

Formats during the working years included 35mm and 120, with sheet sizes appearing intermittently. Today the 35mm cassettes are the only practical find.

Reciprocity exponent is 1.31. Zone Light Meter applies the correction past one second. A metered 30-second exposure becomes about 90 seconds at the negative. Available-light interiors at f/11 and ISO 200 fall into that range constantly, which is one reason the 200 speed was popular with photographers who could still get fresh stock in 2005.

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 1.31.
  • Expired film: if you load an old roll, set the expiry year and storage in the app and the ISO scales for you. B&W negative decay rates are baked in.
