Thank's for the complements. I use a tripod mounted 35mm Minolta SLR
set to bulb and use a remote shutter release cable. The photos you
commented on are all ~5 second exposures. I set the lens at F5.6 and
use Kodak Gold 400 ASA film. I pre-set the camera lens focus on the
Tesla coil topload. Don't use artificial illumination. In my case there
is plenty of light coming off the streamers and rotary gap to illuminate
the entire scene adequately. In this series of pictures I also set my
lens zoom to provide a generous view of the area around the coil to
insure that I'd catch _all_ of the streamer activity. I then cropped
the pictures digitally after scanning the original photographs.
BTW, I think these most recent photographs are my very best so far!
