History
How are radiographs related to photographic history?
Radiographs record X-rays on film or sensors, extending image-making beyond visible-light portraits and scenes.
The V&A describes radiography as capturing X-rays that pass through an object onto photographic film or digital sensors. The first X-ray images were made by Wilhelm Röntgen in Germany in late 1895.
Radiography uses a different part of the electromagnetic spectrum
Radiography uses a different part of the electromagnetic spectrum and answers questions about internal structure rather than surface appearance. It demonstrates that photographic recording is a family of techniques that can visualize what ordinary portrait cameras cannot.

Visible-light portraits and radiographic records
A photobooth is designed around visible-light likeness and a front-facing sitter. Radiographs are adjacent photographic history, not a booth output, but they show how the same broad idea—recording energy on a sensitive medium—supports very different purposes.

A radiograph is not a portrait in the everyday sense
A radiograph is not a portrait in the everyday sense, but it belongs to photographic history because a sensitive medium records transmitted energy. The image’s purpose is diagnostic or investigative rather than expressive likeness. Keep that distinction in view when explaining how photographic recording expanded into scientific and medical uses.
