Good point, and thanks for the warning.

I wasn't thinking so much of fiddling with the flash itself, but with the wiring leading to it, to see if there was a way to bypass the shutter release mechanism in order to trigger the flash. But on sober reflection (not that I was drunk when I made the previous post <img src="/images/graemlins/laugh.gif" alt="" /> ) I probably wouldn't have the tools to do this in a survival situation anyway.
