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

Hi Peter,

This is what son's are for. I handle the coil. My son handles the camera. The camera and my son are electrically connected before the coil starts running. I'm free to do my thing. A second person really helps with camera's and coils (son or whoever).

Take care,

In truth I rarely push the on button these days. I use the standard or long range IR remote to avoid camera shake. If I am working alone then I am also controlling the variac and am grounded to the metal handle but this is well out of harms way. If I am using the camera manually then I will be behind the camera and tripod and there will be very little pickup of HV from my body.

There is still the danger of you acting as an antenna, so that when you
touch the grounded camera the difference in potential between it and you
could be enough to damage the camera.  Wearing a ground strap connected
through a string of a dozen or so 1 meg resistors to ground, or holding onto the tripod with one hand, would make your body potential be closer to that
of the camera, thus avoiding damaging "tingles".

That was me. I do it because I was sometimes getting a little tingle when I
touched the camera when I am standing behind it suggesting the camera is
above earth potential. I don't want that voltage sparking onto the screen or

eyepiece or plastic on button which could damage the camera.
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 to ground.
I stand by my decision to earth the tripod.
