High-speed photography

Definition

High-speed photography is a technique that captures fast-moving subjects using very short exposure times, allowing the freezing of motion in images. This method enables scientists and artists to study and illustrate rapid events that would otherwise be invisible to the naked eye, providing insights into phenomena like the flight of a hummingbird or the impact of a bullet. The advancements in high-speed photography have significantly influenced the techniques used in scientific illustration, leading to new materials and methods for accurately representing dynamic processes.
