Electric spark photography anyone? I have an article on it (for
precisely that and even shorter durations, with all the calculations
et cetera) in my old Focal Press photography encyclopaedia.
Unfortunately, it's a 20-volume set so it's stuffed right in the
cellar and not even under my flat...
Try to search for it on the web though. It's the method for creating
the usually extremely boring images of bullets speeding trough red
apples and similar.
Good light!
