Using stroboscopes in photoshoots and video recording
Can I use a strobe as an external flash for a digital camera?
You can use the x-contact output from the stroboscope to synchronize a stroboscope with a camera shutter to capture high-quality images of high-speed phenomena for use in technical or specialized applications. X-contact output options are available for many single-lens reflex digital cameras. Check the operating manual provided with your camera.
Can I synchronize stroboscope flashes with a video camera?
Ordinary video cameras record images at a rate of 30 frames per second. You can synchronize strobe flashes by setting the strobe frequency to 30 Hz.
You can achieve more accurate synchronization by using a video separator (VS-2 video separator) that separates the synchronization signal from the video vertical signal. Using this device ensures recording of flicker-free strobe images in precise synchronization with the vertical signal.
How can I capture the image of a bullet fired from a gun?
A bullet fired from a gun oscillates very slightly in all directions. You can use a planar sensor (product name: Photo Screen) to detect a bullet or any other flying object that does not follow a straight trajectory and to activate the strobe to flash at the right time. For more information, go to the page describing the "Photo Screen."
Is it possible to capture an image of the cavitation generated by a screw propeller?
Capturing an image of cavitation caused by a screw propeller requires a high-power strobe of 60 W or more capable of providing a short flash duration (5 μsec or less). You must also take into consideration propeller diameter, the dimensions of the water cistern, and other conditions. A pulse generator is useful for adjusting the propeller blade’s position and photo timing. For reference information, see the page, "Video recording of cavitation generated by a screw propeller."
