shadowgraph
Shadow reveals flow
A shadowgraph is an image formed by casting shadows onto a surface.
The simplest form is hand shadows projected on a wall to create animal shapes.
In scientific and medical contexts, shadowgraph refers to images made by passing radiation through an object—an X-ray is technically a shadowgraph.
The word also describes a type of silhouette portrait popular in the 18th and 19th centuries.
