How do you guy's take pictures of DRSSTCs? I can't get anything to look better than a "cloud" or just really dark. My arcs look exactly like Steve Ward's on his site, but I can't get them to take. I've had no problem with my SGTC. I wanted to show you guys my new coil, but I can't get any good pics. NOTHING of the banjo effect, and they look about 1/2 as long as they really are.

I usually use about a .5 to 1 second exposure length at 200 or 400 ISO and the lowest fstop my camera will allow (usually around 2.8 or 3.5). You cant let the exposure go too long, or you will just get a bunch of hazy sparks. Also, try to keep ambient light as minimal as possible.

I generally shoot with a shutter speed of about 1 second and ISO of 100-200 at f/2.8. I keep a small amount of illumination in the room. The key is to experiment with various settings until you get something you like.

you get very interesting spark effects on a picture if you set your camera on a tripod , exposure time up to 15 seconds (of course, the room have to be dark just a dimmed light) and play around with the interrupter , higher and lower the on and off time.
i usually take my pics with 4 seconds exposure and an on time of around 200yS, off time around 5ms, that would give the spark i like , but you have to play around with settings,lighting,distance,exposure time,shutter speed ,or Av as its known here in germany (usually variable between 2,8 and 7 or more) iso between 50 and 500, for darkish rooms usually between 100 and 200.
if your drsstc picture is too dark you can take a exposure time of around 4 seconds , run your drsstc and switch the light on for a short time (nothing more than a moment, switch on, switch off)with the right cam settings you´ll have a nice background light with this technique you´ll get pics like this one

On the same note, how do you guys take digital pictures of tesla coils? My SGTC is driving my camera crazy even from like 6 feet away! Do you always use film cameras?

I think it might be camera dependant, my Canon G5 has no problems whatsoever with my SSTC's. I'm sure SGTC's (the spark gap to be more precise) will give off other frequencies that might be detrimental to the operation of your camera.
