TL;DR:
A photograph is a made object: someone chose what to shoot, when and how.
Ask who took it, what is in and out of frame, and what was happening around it.
Pair the photograph with other evidence and check its caption and date.
A photograph feels like proof: the camera was there, so this is what happened. But a photographer chooses where to stand, when to press the shutter and what to keep, and an editor chooses how to caption and use it. A photograph is strong evidence once you ask how it was made. This article shows the questions on a well-known example.
Where to find usable photographs
The Library of Congress holds a very large online collection of historical photographs, including many taken for the United States government in the 1930s and 1940s. Each record lists the photographer, the date, the caption and a rights statement. Read the rights statement on the record before you reuse an image, since not every item is free of restrictions.
Worked example: a Depression-era photograph
One well-known photograph held by the Library of Congress is "Migrant Mother", taken by Dorothea Lange in 1936 in California. Lange was working for a federal agency that documented rural poverty during the Great Depression. Walk through the questions.
Question | What to look for | Notes for this photograph |
|---|---|---|
Who took it and why? | Photographer, employer, purpose. | A government photographer documenting hardship. The photo was meant to show conditions and build support for aid. |
What is in the frame? | People, objects, expressions, setting. | A woman with children close beside her, looking away from the camera, in a worn setting. |
What is out of frame? | What the photographer did not show. | The wider camp, other families, the people nearby, and what happened before and after the shot. |
When and where? | Date, place, event. | 1936, California, during the Depression and agricultural hardship. |
How was it used? | Caption, publication, audience. | Widely published, which shaped how many people pictured the Depression. |
Now think about what the photograph can tell us. It can show how the photographer and the agency wanted the public to see rural poverty, and the image has been used by many people since. It cannot tell us, by itself, the full story of the people shown or how typical they were. Those questions need other sources, such as records, interviews or later accounts.
A sentence of analysis might read: The tight framing and the children's turned faces focus attention on the strain on the family, which fits the photographer's purpose of documenting hardship for the public, but the image alone cannot show how representative this family was.
Three levels of looking
Describe: List what you can see, without interpretation: people, clothing, objects, setting, light.
Interpret: Say what you think it shows and why, using details as evidence. Offer more than one reading if the image allows it.
Question: Say what you do not know and what other sources would help: the caption, the photographer's notes, newspapers of the time.
Captions and cropping
Read the caption as a separate source. It was written by someone, perhaps the photographer and perhaps an editor, and it guides how you see the image. Cropping can also change the meaning: removing a part of the frame removes some of the context. If you can, find the full frame or other photographs from the same session.
Note: Staged and posed photographs are not necessarily false. Many early photographs were posed because the cameras required it. Ask whether the pose tells you something about the subject or the photographer.
Comparing it with a second image
One photograph rarely settles a question, so find a second one and compare. A different photographer in the same period, from a different agency or a different region, may show other parts of the same story. Place them side by side and ask what each emphasises, what is missing from both, and where they agree.
If you can find several frames from one photographer's session, compare those too. The choice of which frame became famous is itself part of the history: someone decided that one image would stand for the whole situation.
Questions to take to your essay
What does this image let me say that a text cannot?
What does it make me assume without evidence?
Which written source would test my reading of it?
Common mistakes
Treating a photograph as a neutral window.
Describing only what is visible and leaving out analysis.
Forgetting to check the date and caption.
Using one photograph to describe a whole group.
Writing the analysis paragraph
Put a claim first, such as "The photograph presents hardship as a family matter." Follow with a detail you can point to, such as the way the children lean in. Explain what the detail suggests, and then add the limit: what the image cannot tell us. Three sentences like these are enough to show real analysis rather than description.
Keep the language careful. Say "suggests" and "appears to", not "proves". A photograph is evidence that needs interpreting.
Your plan for this week
Choose a photograph from a public collection, read its record, and fill in the table above. Write two sentences of analysis and one question you cannot answer with the photograph alone. DuckyHelper can look at an image on your screen and talk it over with you, and you can ask it what a photographer might have left out of the frame.
Frequently asked questions
Can I use photographs from the Library of Congress in my project?
Often yes, but read the rights statement on each record, and credit the source as your teacher requires.
Is a photograph better evidence than a written source?
It is different evidence. It captures what was visible, but not everything, so combine it with written sources.
