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.

That was me. I do it because I was sometimes getting a little tingle

If you are trying to avoid "unseen leaders" then you are expecting the
camera to be floating at many thousands of volts. Not safe at all.
Secondly, if there was a camera strike while I was holding the camera
(I don't get that close), then I would be protected and not the path
I stand by my decision to earth the tripod.

.. Regarding this thread, I
think I read someone grounding the tripod? That's probably the last
thing I would do for the same reasons for not grounding my body. I'm
not sure I understood that post correctly as I wasn't paying close
attention, but I certainly would not ground the camera or what it's
sitting on (or anything near it). We don't want to issue unseen
leaders shortening the physical distance between coil and camera. IMHO.
