Why Photographers Are Seeking Out Expired Film

Expired film photography is a simple way to get results that are harder to predict than you would with a fresh roll. Colours can shift, contrast can drop, grain can become more noticeable, and some negatives may come out with a hazy or uneven look.

If you already use film, there isn't much new to learn. You load the roll, meter it, press the shutter, and have it developed as usual. What changes is the film itself.

You also don't need to start with a roll that's 30 years old. A film that's a few years past its expiry date can be enough to show some changes, particularly if it hasn't been stored well. A refrigerated roll may look surprisingly normal, while another roll of the same film and the same age may be heavily affected by heat. That makes the expiry date useful, but not particularly informative on its own. How the film was stored matters just as much.

What Actually Happens to Film as It Ages

Film contains light-sensitive materials that are designed to remain stable until they're exposed and developed. They don't stop changing just because the film is sealed in its box.

Over time, heat, humidity, background radiation, and chemical changes in the emulsion can affect the film. Colour film is more complicated because it has several layers, each sensitive to different parts of the visible spectrum. Those layers don't necessarily age at the same rate, which can lead to colour shifts.

Film can also develop fogging. In simple terms, fog is unwanted exposure across the film. Instead of only recording the light coming through the lens, the film develops a general veil over the negative. Mild fogging can make a photograph look flatter or hazier. More severe fogging can hide detail.

The film can also lose some of its sensitivity. A roll that was rated at ISO 400 when it was new may no longer behave like ISO 400 after years of storage. Worth thinking about before you load an expired roll: exposure

The Effects You Can Expect

There isn't one predictable “expired film look.” You might get obvious changes, or you might get a roll that looks almost completely normal.

Common effects include:

• Colour shifts: Colour-negative film can become warmer, with more red or yellow, or shift towards blue, green, or magenta. Colour reversal, or slide, film can show particularly strong colour changes.
• Fogging and haze: A layer of fog across the negative can lower contrast and make the photograph look washed out or hazy.
• More visible grain: Grain may become more noticeable, especially with faster films such as ISO 400 and ISO 800 stocks.
• Lower contrast and saturation: Blacks may not look as deep, while colours can lose some of their strength.
• Uneven density or streaking: Poorly stored film can sometimes develop uneven areas or marks. Instant film can have its own problems as its chemistry ages.

Black-and-white film is generally a little easier to deal with because it doesn't have multiple colour-sensitive layers. It can still lose sensitivity, gain fog and become grainier, but there are fewer colour variables to contend with.

None of these effects are guaranteed. An expired roll can produce something interesting, something ordinary or, in the case of badly deteriorated film, very little worth keeping.

Storage Matters as Much as Age

Two rolls can have the same expiry date and behave completely differently.

Film stored somewhere cool and dry has a much better chance of retaining its original characteristics than film that's spent years in a hot attic, garage or car. Heat speeds up the chemical changes taking place in the film.

A seller telling you that a roll “expired in 2010” doesn't tell you everything you need to know. If it was refrigerated for most of that time, that's useful information. If nobody knows where it has been for the past 15 years, the result is much harder to predict.

When buying expired film, ask about storage if the seller knows. Look at the packaging, too. Avoid rolls with obvious water damage, crushed packaging or other signs that they've been poorly handled.

For instant film, storage is especially important. Polaroid recommends keeping unused film sealed, cool and dry. Refrigerated film should be brought back to room temperature before use.

How to Capture It – The One Rule Worth Knowing

The rule of thumb when it comes to using expired film is to add about one stop of exposure for every 10 years past the expiry date. A stop is simply a way of describing the amount of light reaching the film. One extra stop means twice as much light. So, if you have ISO 400 film that's 10 years expired, you could rate it at ISO 200. For film that's 20 years expired, you could try ISO 100.

On a camera with a manual ISO setting, you can make the adjustment yourself. If the film says ISO 400 and you want to give it one extra stop, set the camera to ISO 200. The camera will then meter for the slower film speed and give the film more light. If you're using a handheld meter, set the meter to the ISO you're rating the film at and meter normally.

The one-stop-per-decade guideline is just that: a starting point. It doesn't account for storage, film type or the actual condition of the roll. A well-stored roll of Kodak Gold 200 may need less compensation than a badly stored roll of the same age. Slide film, or colour-positive film, is another case where you need to be more careful. It has less exposure latitude than colour-negative film, so getting the exposure wrong can be much harder to recover from.

If this is your first time using expired film, there's little reason to start with the oldest roll you can find. Try moderately expired colour-negative film first. Write down the expiry date, the ISO you used, and anything you know about how the film was stored. You'll have something to compare when you try another roll.

Where to Find Expired Film

Expired film turns up in more places than you might expect. Independent camera shops, online marketplaces, estate sales, garage sales, and inherited camera collections are all possibilities.

You may come across familiar films such as Kodak Ultramax, older professional stocks like Fujifilm Pro 400, or rolls that have simply been sitting in someone's camera bag for years.

Check the expiry date, but don't stop there. Look for damaged packaging and ask about storage. If the seller knows the film was kept refrigerated, that's worth knowing. If they have no idea where it has been, factor that into what you're willing to pay.

There's also no good reason to spend a lot on an expired roll when you're experimenting. A cheap roll with a known history is often a better place to start than an expensive roll that's been sitting in unknown conditions for decades.

What to Do Once You've Captured a Roll

Expired film doesn't normally need a special development process just because it's expired. Colour-negative film is still processed using C-41 chemistry, while traditional black-and-white film is processed using black-and-white chemistry.

When you drop off an expired roll, tell the lab that it's expired. If you know the age and storage history, pass that along, too. It gives them some context for what they're working with.

At Annex Photo, 35mm and 120 colour and black-and-white negative film can be processed and scanned. Scanning is a good way to see what you've got before deciding whether anything is worth printing.

With an expired roll, you may see colour shifts, fogging, extra grain, or uneven density in the scans. You may also find that the film looks much more normal than expected.

Keep the negatives after they're processed. They're the original version of the image, and you can always revisit them later with a different scan or printing process.

Give Expired Film a Try

Expired film isn't a trick for making better photographs. It’s one more thing you don’t fully control — and that’s kind of the point. Start with a roll that's moderately expired, find out how it was stored if you can, and give yourself a little extra exposure as a starting point. Then see what happens.

You might get warm colours, heavy grain, or a hazy negative. You might get almost none of those things. That's part of using old film: you don't know exactly how it's going to behave until you develop it. If you've got an expired roll sitting in a drawer, bring it to Annex Photo. We can process and scan 35mm and 120 colour and black-and-white film and see what's left on the roll.
