Rod,

One advantage of placing the filter over the flash would be to disguise the
fact that you are taking a photo, or to avoid disturbing someone/thing with
a burst of flash light.

If you have no need to hide the flash light then simply use the filter on
the lens.

If the scenario is night photography with no ambient light then you could
use a filter on the flash and none on the lens, however you would not be
able to see to focus anyway :-)


You would not need a filter over both flash and lens if there is little
ambient light - ie at night and away from visible and IR light sources.


I will add a little more to the flash section in the Infrared FAQ (URL in
sig. file) to cover these different scenarios.



All the best,
