[TCML] top load and photography (tripod grounding)

[bartb]

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,
Bart
