4 sec. at F2.8 works great with ASA 100 color film.
If possible, hang a vertical ground wire near the coil and use a
discharge point off the coil. The spark will strike the ground wire
and "climb" upwards with the hot air currents. Excellent photographs.
I will email you some off-list so you can see what I mean.

Greetings all,
I am having trouble getting good pictures of my Tesla coil in
operation. It seems the cameras I have available, do not have a
very adjustable exposure time (and I don't have any clue how to
take a double exposure, without using conventional film, which is
useless to me as I don't have a scanner, so I cannot put my
pictures on the computer). I can get "decent" videos, but still
shots captured from them generally only show the arcs, and not the
coil (which gives no perspective of actual size), plus the DPI is
too low for my taste anyway. Any suggestions would be appreciated
(even referrals to the archives would be great, if you could give
me a general place to look, they are vast, and I am pressed for
time!) Thanks a heap.
Scott Bogard.
