How to Read Photographs as Primary Sources: A Historian’s Guide

In the hushed reading room of The National Archives in London, a researcher holds a faded photograph from 1893. It shows twenty-seven girls and two boys standing before a coal mine, dressed in rough working clothes, caps askew, faces turned toward the camera. The handwritten caption reads: “Pit Brow Girls, just before starting their work.” The image is arresting—but what does it actually tell us? Does it reveal the conditions of Victorian women’s labor, or does it merely reflect the photographer’s staging? For the historian, a photograph is never a transparent window into the past. As the archivists at The National Archives remind us, “Seeing is not necessarily believing!” (source: [3]). This guide, built on the analytical frameworks developed by The National Archives and the Library of Congress, explains how to approach photographs as primary sources—how to observe, reflect, question, and interpret them with the rigor of a professional historian.

What Happened?

The practice of using photographs as historical evidence dates to the earliest days of the medium, but it was only in the late twentieth century that archivists and historians formalized a systematic method for analyzing them. The National Archives (UK) and the Library of Congress (US) now publish structured guides for students and researchers. Their approaches converge on a simple yet powerful idea: a photograph is a constructed artifact, not an unmediated record of reality.

The National Archives’ “What can a photograph tell us?” activity, built around the 1893 Pit Brow Girls photograph, suggests a sequence of eight questions:

• What type of source is this?
• Who produced it?
• When was it produced?
• What can we infer from this photograph?
• What values or attitudes does the photograph suggest?
• How does the photograph relate to a historical situation?
• Are there any clues about the audience of the photograph?
• How reliable is the photograph?

The Library of Congress Teacher’s Guide (source: https://www.loc.gov/static/programs/teachers/getting-started-with-primary-sources/documents/Analyzing_Photographs_and_Prints.pdf) similarly structures the process into three phases: Observe (describe what you see, note details), Reflect (generate and test hypotheses about why the image was made, its audience, and what is missing), and Question (ask who, what, when, where, why, how). These methods are not arbitrary; they are designed to force the researcher to move beyond a naive reading of the image and to treat the photograph as a deliberate human product.

How It Was Seen at the Time

At the time these guides were published—and in the broader practice of modern archival pedagogy—photographs are understood as complex documents that require the same caution as written records. The National Archives states plainly: “Just like documents they must be treated with caution. Seeing is not necessarily believing!” (source: https://www.nationalarchives.gov.uk/education/students/working-with-photographs/). The same page warns that “there are quite a lot of things you need to watch out for when using photographs as sources.” This caution reflects a broader historiographical shift that began in the 1970s and 1980s, when social historians and visual culture scholars argued that photographs were not objective records but constructed representations shaped by the photographer’s choices, the technology available, and the social context of the shoot.

This perspective is not merely theoretical; it has practical implications for research. For example, the 1893 Pit Brow photograph was taken by a professional photographer and later registered with the Copyright Office (COPY 1/412). The fact that it was a formal, staged portrait—not a candid snapshot—immediately tells us that the subjects were posed, that the photographer had a specific purpose, and that the image may have been intended to document or even romanticize the women’s work. Such knowledge does not negate the photograph’s value, but it forces us to ask: whose point of view does this image represent?

What the Sources Got Wrong

One of the most common errors in using photographs as primary sources is to treat them as transparent evidence. The National Archives warns that photographs must be “treated with caution” because they are subject to the same biases as any document (source: https://www.nationalarchives.gov.uk/education/students/working-with-photographs/). For instance, the Pit Brow photograph was likely staged for the camera; the subjects were arranged, the lighting was controlled, and the photographer chose the angle. An inexperienced researcher might conclude that this is a spontaneous snapshot of Victorian working conditions, when in fact it is a posed portrait. Similarly, the Library of Congress guide instructs researchers to ask “What’s missing from this image?”—a reminder that photographs are always partial and can omit crucial context, such as the dirt, noise, and danger of the mine (source: https://www.loc.gov/static/programs/teachers/getting-started-with-primary-sources/documents/Analyzing_Photographs_and_Prints.pdf).

Another misconception is that photographs are objective records because they are mechanically produced. The National Archives explicitly counters this by pointing out that photographs are “constructed” and that “seeing is not necessarily believing” (source: https://www.nationalarchives.gov.uk/education/students/working-with-photographs/). In the 1893 Pit Brow photograph, the fact that the girls are clean, posed, and smiling (or at least not visibly dirty) may reflect the photographer’s desire to present a respectable image, not the reality of their work. A careful historian must therefore cross-reference the photograph with other sources—census records, factory reports, or newspaper accounts—to correct these distortions.

How Historians See It Today

Modern historical scholarship has moved from a simple “illustrative” use of photographs to a critical, contextual analysis. The Library of Congress’s framework of Observe, Reflect, Question is now a standard pedagogical tool, and the National Archives’ eight-question model is widely used in classrooms. These methods encourage historians to treat photographs not as windows but as “constructed representations.” The academic framework described in the “Exploring Historic Photographs in an Academic Setting” (source: https://kstatelibraries.pressbooks.pub/primary-resources/chapter/exploring-historic-photographs-in-an-academic-setting-a-framework-2/) emphasizes an iterative process: “observe, identify, interpret, analyze.” It suggests that the researcher must “forget what you think your audience wants you to see and instead examine the photograph for what it shows.” This approach recognizes that every photograph is a cultural artifact, shaped by its producer, its intended audience, and the technology of its time.

Historiographically, this represents a significant shift from the early twentieth-century view that photographs were “automatic” records of reality. Today, historians are more likely to ask who commissioned the photograph, who was excluded from the frame, and what the photograph reveals about the power dynamics between photographer and subject. The Pit Brow girls photograph, for instance, is now seen not only as evidence of women’s industrial labor but also as a product of the photographer’s gaze—a gaze that may have been voyeuristic or sympathetic, but that certainly shaped the representation.
