It is always recomended that you bring a xerox of your passport in case it is lost or stolen. I just photograph it with my digital camera and E-mail it to myself and leave it in my inbox. That way it is in cyberspace, I just need an internet connection in case I lose my original. I do it with my NAUI certification too. Just another backup system. Never had to use it.

That's a great idea, never thought about that one. I always carry a xerox copy of mine.
It’s a really good idea.
Just few technical details: what F number is recommended for the shootings? Strobes position? How do I get deep blue background?
I did something similar where I scanned the passport and sent it to email, and kept a copy on my memory stick.
