shadowgraphy

Shadowgraphy is a technique used to create images based on shadows cast by objects. This method involves placing an object in front of a light source, which generates a silhouette. The resulting shadow can reveal details about the object's shape and structure, making it useful in various fields such as art, education, and science. In scientific contexts, shadowgraphy helps visualize the flow of fluids or the movement of particles by capturing their shadows on a surface. This technique provides valuable insights without needing to touch or alter the objects being examined.
