Hi,

Some of the best results I've achieved have been by using a low 
wattage bulb (100watts) illuminate the coil itself which also helps 
the camera to focus (assuming it's AF) set the camera to program 
mode, the highest ISO setting available and set the exposure 
compensation to -2. The latter tends to stop excessive shutter times. 
The subject material i.e. the streamers are very small in area 
relative to the whole scene, budget cameras tend to meter the light 
as an average for the whole scene, so if you try for neautral or + 
exposure compensation the picture will end up very grainy with lots 
of pixel noise.

Hope this helps, Ian

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.
