RE: Photo Technique
Ted,
That is exactly what I did last year (it was cold and rainy outside so I was
running at a lower power inside). Check out

I set the camera one f-stop higher (smaller opening) and took the flash
picture first. Then cocked the shutter (without advancing the film). I then
opened the shutter in the dark and let the arks fly.
Regards,
Brian B.

Just a suggestion to those whose coils are working and who have FILM cameras
that can take a double exposure.
Yes, I know that's a lot of 'ifs' but if my coil were finished, I'd show
y'all what I'm suggesting.
1. Set the camera on a tripod
2. With room lights on, take a photo of the coil showing as much as you need
while allowing for spark distances later.
You can even use flash if need be.
3. Do not advance the film but recock the shutter. Some 35s (like older
Minoltas) let you hold the rewind button in while you recock the shutter.
4. Start the coil and this time take a time exposure of several seconds with
the lens closed down to at least F/11.
The resulting photo should give you the best of both worlds: a great shot of
the coil and the best sparks it can produce in total darkness.
I hope to demonstrate this when my TC breaks first light around April.
Ted
