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

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.
