I think that is wishful thinking. I don't think your average electrical field emits IR or UV. It is the interaction with its surroundings which causes that.
But I may yet stand corrected. I wonder if there are any physycists in our midsts?

and though a time lapse image of the Z machine releasing about 80 times the world's entire electrical power usage for a brief fraction of a second, it is an electro-magnetic field, albeit a massive one. I was wondering if their was a technique of recording the fields created through domestic power generation, though they are invisible to the naked eye.

That is not an image of the electrical field per se.
That is the plasma created by the arcing of electrical currents. Basically, indoor lightning. You'd need a lot of power to create something like that, but it'd be good fun to see.

Nope, no idea how you would do that.
But throwing iron filings into the air to be caught by the magentic fields areound them would definitely not be a good idea.
( Unless you got someone you didn't like to do it for you )

What type of electrical field?

NO!
Some people have no respect for where they are!

Hopefully the priest will allow one or two. I wouldn't dream of wandering around with the camera.
I think I'll get what I can on the day, then try again when the church is empty. The kids get to wear their Communion outfits for mass the following day. With my eldset I got to the church 1/2 hour before everyone else and took a couple of shots on the altar ( with the deacon's permission ).

Lovely shots. I like number 2 the best, but all are cracking shots.

Just a thought... have you actually asked if you can use flash? Its been my experience that some churches/priests are much more accommodating than others.

There'll be a meeting the week before, so I'll ask then.

But, I always follow Gwyn's advice above when I change lens, so maybe I've been lucky.
