Abstract: The vibration characteristics of photography tripod are studied based on its mathematical partial differential equation. The displacement of tripod vibration caused by the impact due to camera shutter release is analyzed. Applications in engineering are described and examples are given. The results are useful for both tripod users and manufacturers.

Key words: photography tripod, longitude vibration, partial differential equation, maximum magnitude of vibration
