Pruebas de cámara de alta velocidad en 5000 marcos por segundo con sugerencias prácticas y consideraciones de iluminación
Tiene 13 años. Es posible que el equipo y los precios hayan cambiado desde entonces.
Lo que encontró el hilo
- Una cámara de alta velocidad de 5000 fps requiere iluminación significativamente más potente que el disparo convencional, con iluminación LED lo suficientemente brillante como para requerir protección de los ojos durante la operación.
- Las imágenes de alta velocidad revelan detalles finos en eventos rápidos como el comportamiento de la condensación de agua volando fuera de una lata depresurizada rápidamente, el desgarro de vidrio y los patrones de salpicadura líquido.
- Lighting for high-speed shots in confined spaces like a hotel room can be achieved with a full LED kit providing adequate illumination across approximately five feet by five feet.
- CRT screen and old television displays may show visible scanning patterns when filmed at 5000fps.
- Subject matter suitable for high-speed cinematography in limited spaces includes breaking glass, liquid splashing, object impacts, structural deformation under force, and combustion events like matches or lighters.
Depende de
- Setup was conducted in a hotel room environment with limited space and equipment availability.
- The operator had less time for experimentation than initially planned.
- Testing was limited to materials and subjects readily available during the shoot.
- Some suggested subjects like Never Wet coating were unavailable in the region where filming took place.
- Results were promised but not confirmed to have been completed and published.
