The value of analog photography

Learning goal

You will be able to explain in what ways film photography differs from digital and why it is still chosen today. You will describe how in analog photography the image forms on a light-sensitive film, first as an invisible latent image, and appears only after development. You will discuss how the frame limit on a roll and not being able to see the result right away slow down the way you shoot, and how film grain and exposure latitude give a film its character. You will also weigh honestly the cost, effort and chemicals of film, and see film not as superior or inferior to digital, but as another way of working. You will remember how film historically showed dark skin poorly, and learn how you can think about exposure today to keep shadow detail in dark-skinned faces when shooting on film.

The question

After the exhibition breaks up, the older member takes an old camera with a metal body out of a cloth bag and hands it to your friend. Inside is a roll of film with thirty-six frames. "Shoot only with this for a month," they say. Your friend turns the camera over and over: there is no screen on the back, no menu, only a shutter speed dial, an aperture ring and a frame counter.

On the first day they shoot only four frames. Each time, before pressing the shutter, they think for a long time, then out of habit look at the back of the camera and remember there is nothing there. Why is film still alive? With cameras that show hundreds of frames within seconds, why do people choose a method whose number of frames is limited and whose result is seen days later?

Context

While telling the short history of photography you saw the road from light-sensitive surfaces to the negative (Lesson 1.2). In the ISO lesson, too, you learned that ISO numbers come from the film era and that the word grain comes from the grains in film (Lesson 8.6). While following the movements in photography, we discussed which face labs looked at to set colors, and whose face this left poorly shown (Lesson 26.1).

This module carries that history inside a camera. Although digital cameras have taken over most everyday photography, film hasn't disappeared; many photographers, students and artists keep choosing it knowingly. This lesson tries to understand what film does differently; the following lessons will take up film types, using an analog camera, development and scanning step by step.

Simple explanation

How does film record the image?

Analog photography is a photographic method in which the image, instead of turning into numbers on a sensor, is recorded as a chemical change on a light-sensitive film or paper. On the surface of the film there are very small light-sensitive crystals of silver compounds. When the shutter is pressed, light changes some of these crystals; but this change can't be seen with the eye.

A latent image is the trace light leaves on film that isn't yet visible, and it turns into a visible image only after it is developed. This is why there is no screen to look at on the back of your friend's camera: the frame exists inside the film the moment it is taken, but no one can see it. If the film is exposed to light before being developed, the latent image is erased; that is why the roll is rewound so it stays in the dark before being taken out of the camera. This waiting is the most noticeable difference of working with film: the photographer sees the frame they took hours, days, sometimes weeks later. The negative that comes out of development is also an object held in the hand: held up to the light, the frames can be seen with the naked eye, it can be kept for years in an envelope or sleeve, and it stays readable even when a file format becomes obsolete.

Why can limitation and slowness be valuable?

The frame limit is the fixed number of frames a roll of film can carry; on common thirty-five-millimeter rolls it is usually twenty-four or thirty-six, and on medium format rolls fewer frames depending on the format. Every frame costs money, time and development effort. This limit pushes many photographers to stop before pressing the shutter and think more carefully about the framing, the light and the moment. Instead of shooting dozens of frames of the same scene and choosing later, deciding on a single frame calls for another kind of attention.

Not being able to see the result right away also changes the way you shoot. On a digital camera, looking at the screen after every frame pulls the photographer out of the scene for a moment; with a film camera the eye stays in the scene. Your friend looking at the back of the camera out of habit shows how settled this break has become. Slowness also has a price, and it needs to be weighed honestly. Film and development are much more expensive per frame than digital shooting; sending the roll to a lab takes time and money, and developing at home means working with chemicals, storing them safely and disposing of used solutions according to local rules, without pouring them down the sink. Mistakes are more expensive too: a wrongly loaded roll or a back that leaks light can erase frames shot over weeks in one go. A result that arrives days later also lets you look at the frame from a different distance: the excitement of the moment of shooting has passed and the frame is read more coolly. This slowness doesn't suit everyone; shooting fast-moving news or a wedding only on film can be an unnecessary risk for most photographers. The value of limitation comes from the photographer choosing it as a tool; many photographers use film only in their personal projects, and digital in their work.

Where does film's character come from?

Film grain is the irregular, fine texture that clusters of silver or dye in developed film form in the image. In films with high sensitivity the grain is usually more noticeable. Although grain resembles digital noise, it shows a different distribution, and many photographers see it not as a flaw but as the texture of the image. The same scene looks different in color, contrast and grain on different films; when a photographer chooses a roll, they are actually choosing a look too. In digital this look can be changed after the shoot with an editing preset; with film the decision is made the moment the roll goes into the camera and doesn't change for thirty-six frames. The soft light of morning and the hard sun of noon are recorded with the same film's colors and grain; the photographer learns to choose the light according to the film or to predict the film's response in advance.

Exposure latitude is the range within which a film can still carry usable detail when you move away from correct exposure. Color and black-and-white negative films are usually quite forgiving of overexposure, but when they are underexposed the detail in the shadows is lost quickly. That is why many photographers working with negative film prefer to overexpose the film slightly, especially in a frame where the shadows matter.

This knowledge also matters for skin. Because labs' color settings were made for decades according to a light-skinned face, the shadows of dark-skinned faces in old prints often stayed without detail. Today, when shooting portraits on film, pointing the light meter not only at the surroundings but also at the face, and keeping the exposure a little generous so the shadows in a dark-skinned face carry enough density in the negative, is one of the ways to keep the texture of the skin.

Visual evidence

Your friend sets aside one of the first frames of the roll for a portrait of their neighbor sitting by the window. The neighbor's skin is dark and the room is dim. On their digital camera they would look at the screen and correct it; here they have one chance. They bring the light meter close to the face and meter, and remembering negative film's tolerance for overexposure, they give one stop more light.

It takes them three weeks to finish the roll at thirty-six frames. In the negatives that come back from development some frames are blurred, two frames are completely blank, and one has been accidentally exposed twice. But in the neighbor's portrait the shadows on the cheeks are detailed; the texture of the skin sits within a fine grain, together with the soft light coming from the window.

Your friend puts this frame side by side with a frame they shot the same day with their digital camera. Both are good; but the digital frame is sharper and cleaner, the film frame softer and more textured. They can't decide which is better and realize that this isn't the right question to ask.

Common mistakes

Summary

In analog photography the image is recorded on a light-sensitive film as a latent image that becomes visible after development; a limited number of frames on a roll and not being able to see the result right away slow down shooting and keep the photographer's attention in the scene. Film grain and exposure latitude give each film its own character, but film isn't superior to digital, it is another way of working; when shooting dark-skinned faces on negative film, metering the light from the face and keeping the exposure a little generous preserves the shadow detail that was often lost in history.

Mini assignment

In this assignment you will shoot for a week on film or by imitating film's limits.

1. If you have a film camera, load a roll; if not, turn off the screen on your digital camera or tape over it, and set yourself a limit of thirty-six frames for a week.
2. Before shooting each frame, write in your notebook in one line why you are shooting it; don't look at the screen or the frames you have shot until the week is over.
3. Shoot at least one portrait; meter the light from the person's face and, if it is a dark-skinned face, keep the exposure a little generous to preserve the shadows.
4. At the end of the week open the frames for the first time; write a short note comparing, with a week you shot out of digital habit, the number of frames, the hit rate and how it made you feel.

Answers

1. B — The trace light leaves on film is invisible; development turns it into a visible image.
2. C — Negative film carries extra light well, but loses the detail in the shadows quickly when underexposed.
3. A — Because every frame is limited, the photographer tends to choose the framing and the moment more carefully.
4. D — Metering from the face and giving a little more light keeps the shadows of dark skin at enough density in the negative.

Summary card

• Film records the image latently; development makes it visible.
• The frame limit and the waiting keep attention in the scene.
• Grain and color give each film its own character.
• Negative film forgives too much light, not too little.
• On a dark-skinned face, meter the light from the face and expose generously.

Bridge to the next lesson

When the roll is finished, your friend goes to the photo shop to buy a second film and pauses in front of the shelves. There are color films, black-and-white films, and boxes that say slide. Some are in small boxes, some in thicker rolls wrapped in paper. The seller asks which camera they use and what they want to shoot; your friend can't give a clear answer to either. Which film should I buy? The next lesson takes up the differences between color, black-and-white and slide films, and between thirty-five millimeter, medium format and large format.
