Knowra Chronophotography Chronophotography Chronophotography records successive phases of movement as a sequence of photographs, often using a fixed camera and regular time intervals. It made motion available for visual analysis.
Sequential photography : Photography that records a subject in a succession of images, usually to show change over time. Chronophotography is an early, analytical form of photographing successive moments.
Eadweard Muybridge : A British photographer known for sequential images of animals and people in motion. His 1870s horse photographs made chronophotographic motion studies widely known.
Animal locomotion : The ways animals move from place to place, including walking, running, and flying. Chronophotographs exposed the phases and timing of gaits that ordinary vision could not resolve.
The Horse in Motion : A series of photographs by Eadweard Muybridge depicting a horse at successive moments in a gallop. The sequence showed that a galloping horse briefly lifts all four hooves from the ground.
Shutter : A camera mechanism that controls how long light reaches the photosensitive surface. Shutter duration determines how much movement each chronophotographic image records.
Étienne-Jules Marey : A French physiologist who developed instruments for recording movement, including photographic methods. He systematized chronophotography as a tool for studying bodily movement.
Human locomotion : The patterns and mechanics of human movement, especially walking and running. Researchers used sequential images to compare bodily movement across successive phases.
Fusil photographique : Étienne-Jules Marey's portable camera, shaped like a rifle, that captured successive images on a rotating plate. Marey's instrument brought chronophotographic recording into a compact, mobile device.
Frame rate : The number of images captured or displayed per second. The interval between exposures sets the temporal detail in a motion sequence.
Leland Stanford : An American industrialist and politician who funded Muybridge's horse-motion photography. His wager and patronage helped initiate Muybridge's celebrated galloping-horse study.
