Chronophotography
Collection of chronophotographs for studying motion
Chronophotography allows you to visualize different positions of a moving object in a single image. The time interval (dt) between each position is indicated.
What is chronophotography?
Chronophotography is a photographic technique that involves capturing multiple images of a moving object at regular intervals and superimposing them on a single image. This method, invented by Étienne-Jules Marey in the 19th century, allows for detailed study of motion. Today a smartphone can produce these sequences directly, since its camera relies on the same image sensor described in our complete guide to smartphone sensors to record each frame.
How to use these images with FizziQ?
- Download the image by right-clicking on it
- Import it into FizziQ Web via the chronophotography tool
- Use the indicated time interval (dt) to calibrate your analysis
- Point the successive positions of the object
- Analyze the trajectory, velocity, and acceleration
