Re: [TCML] top load and photography (tripod grounding)

Actually Peter, the tingle was probably due to "you" at a high potential 
and not the camera. I understand keeping the body at the same potential 
as the camera. This is perfectly acceptable and understood. But, the 
grounding of either you or the camera is simply something I personally 
would not do. I also won't run a coil bare foot for similar reasons. As 
you say, if a camera strike occurred to the camera or tripod itself, 
yes, most likely you would be protected. However, if you are touching 
the camera "you" become grounded. The strike might hit you instead of 
the camera. Well, the strike will travel through you to get to tripod. 
Think about it.

The main thing is to stay out of harms way and that you are doing.

Take care,
Bart
