Not movies, but still shots can be taken by timing the flash and holding the
shutter open in a dark area. Dick Smith (maybe it was Jaycar?) sells a Light
and Sound Trigger kit that will allow you to take (adjustable) slightly
delayed shots after being triggered by either another flash, or a sound like
a balloon bursting.
I made one many years ago and also added a contact make and contact break
trigger so I could do other scenes, Lets you use the speed of the flash to
freeze motion to about 1/10000 second if the flash output is restricted and
kept low. This trick can require a fast lens.
I've made mine to play with my film camera, haven't tried it with my Nikon
Coolpix 900S, 'cause it's flash has died and it won't even drive the
external flash socket. Of couse, being that old, it's not worth repairing,
but one of these days I'll get the fancy new model and still have the extra
lenses to go with it.
As you are posting to aus.electronics I assume you have some idea about
electronics. You could use a slow speed camera that is cheaply available as
long as you can hook it up to a triggered flash systen that can recycle at a
suitable speed to match the frame rate. If you wanted to capture 1 second of
film at 25 frames a second, then you might want to trigger 25 seperate flash
units one after the other with a softbox to difuse the light.
Or, if it's a bouncing ball from the side of the pub pool table that you
want to capture, you might like to do it as several flashes in a row during
one shutter opening. The Nikon SB24 and later version flash units all had a
multiple flash setting for doing this.
Hope this helps,
Peter
