Um :hmmmm:....NO! :nonono:...I would NOT!
No one is perfect 100% of the time...he could hit that shot 999 times out of 1000 and it would only take that 1 missed hit to put you in a permanent coma or maybe even a coffin :-S
There's just no way to get 'out of the way' in time if it goes wrong :what:
There are some things that ARE definitely worth risking your life or your functionality for...but getting a good photograph?...NOT one of those things! :nonono:
Benefit vs. risk is just not in balance in my opinion!
