There's a refrigerator in our studio that doesn't hold lunch.

Inside the fridge, stacked between cold walls, sit rolls of film — some discontinued decades ago, others pulled from motion picture lots that never made it to a cinema projector. Kodak Vision 2, tungsten-balanced and waiting for its ECN-2 bath. Technical Pan, a scientific emulsion so fine-grained it was once used to photograph the surface of the sun. Agfachrome slide film with a March 1985 expiry and a color palette that Fuji and Kodak never quite replicated.

We call it Film Fridge because that's what it is — a working cold-storage unit kept between 35 and 45 degrees Fahrenheit, the range that slows the chemical aging of silver halide emulsions to a crawl. Every roll we sell has been stored this way from the moment it came into our hands. Some arrived from estate sales, others from old camera shop back stock, a few from fellow collectors who decided it was time to let something go. We inspect, organize, and catalog each one before it goes into the fridge.

Not all of it is precious. Some of it is fun — consumer-era color stocks from Konica and Photoworks that deliver the kind of warm, imperfect frames people now associate with the look of the early 2000s. Some of it is genuinely rare, the kind of emulsion that hasn't been manufactured in twenty years and won't be again. We price accordingly. A roll of Photoworks 400 costs less than a coffee. A roll of Technical Pan costs what it's worth to someone who knows what it can do.

To us, expired film is useful film. It is film with a history, and every roll carries a set of variables — storage conditions, emulsion batch, age — that make the results unpredictable in a way that digital capture cannot replicate. Grain shifts. Contrast bends. Color drifts in directions no preset can simulate because the chemistry is doing something no algorithm anticipated. Shooting expired film is an act of trust in a process you can't fully control, and the frames that come back are yours in a way that a perfectly exposed digital file never quite is.

That said, we believe in giving photographers every advantage. Which brings us to the datasheets.

The Datasheets

When Kodak manufactured Technical Pan, they published a technical data sheet — a dense, precise document detailing the emulsion's spectral sensitivity curve, its resolving power at various contrast ratios, recommended developers and dilutions, reciprocity failure characteristics, and the specific agitation sequences that would yield continuous-tone pictorial results versus high-contrast copy work. The same was true for every professional and specialty stock they made, and for many of the films produced by Ilford, Fuji, Agfa, Foma, and Rollei.

These documents were never meant for casual reading. They were written for lab technicians, cinematographers, and industrial photographers who needed to know exactly what a piece of film would do under controlled conditions. But for anyone shooting expired or discontinued stock today, they are invaluable — often the only surviving record of how an emulsion was designed to behave.

We've been collecting these datasheets for years. Original PDFs sourced from manufacturer archives, scanned documents from technical libraries and film stocks we receive, specification sheets that accompanied bulk orders. Our collection covers motion picture stocks like Vision 3 and Double-X, classic black-and-white emulsions from Kodak and Ilford, color negatives from Fuji and Konica, reversal films, duplicating stocks, and even infrared aerochrome. Where a film is available in our store, we link directly to its datasheet from the product listing so you can read the manufacturer's own guidance before you load the cassette.

The datasheets are freely available to anyone — you don't need to buy film from us to access them. We maintain them because we think the technical heritage of photographic film is worth preserving, and because the information in a fifty-year-old Kodak data sheet is still the best guide to getting the most out of a fifty-year-old roll of Kodak film.

Shoot with Confidence

Every roll in Film Fridge has been cold-stored, cataloged, and matched to its original manufacturer documentation when available. Stock levels update in real time — what you see is what we have. We ship within the United States via USPS or UPS, and San Francisco locals can arrange pickup in the Inner Sunset.

If you're new to expired film, start with something forgiving — a roll of Tri-X or Konica VX100 — and bracket your exposures. If you already know what you're looking for, you might find something in the fridge that you haven't seen in a long time.
