I am using 2 flashes to get a double exposed image and want the light
to be uniform in each exposure. The problem is that I am using 2
physically seperate strobes for the flashes, because the 2 flashes
come from different locations I expect the double exposed image appear
to have motion.

Im looking for a device to make the difference in the 2 different
flash origins irrelevant. Does anyone have any specific
recommendations on equipment?

Some more information on this application:
The 2 flashes are different colors one red the other green, which is
why they have to be 2 seperate devices.
This is being used for taking pictures of particles in a flow under
a microscope so the area that needs to be illuminated is less than 2mm
X 2mm (1/10th inch).
The xenon flash tubes are removed from the housing and setup close
to eachother ~12mm (1/2 inch) from eachother.

I know this is a little different from the normal material for this
group but as I don't have any experience with advanced photography and
no local camera shop (except best buy) any advice would be greatly
appreciated.

Thank You,

Kurt
