Hello Forum.

Modern cameras and flash units support a feature called "High Speed Sync."

As far as I can tell, this is a matter of an electronic flash unit pulsing for longer than the time of the sync shutter speed, so that light is available to the whole frame even if only a tiny open slit is running across the film/sensor.

FP flash bulbs did this a generation or two ago.

Here is my question:

Does anyone here know of a flash which provides, or can be hacked to provide, flashed pulses for an amount of time which equals or exceeds the sync speed of a classic film camera like F2, M3 or whatever?

Electronic FP flash emulation for manual focal plane shutter equipped cameras, in other words.
