Re: Tesla Coil Photography



to: Terry, Alex

I agree strongly with Bill on this technique.  I always use Fuji Velvia
color slide film.  It has a tremendous response to blue/purple spectral
colors and produces excellent color saturation in this portion of the
spectrum.  Wide open F1.2-1.4 and let 'em burn for 3-6 seconds.  I usually
use 4 sec exposures for large coils and 6 sec for smaller setups (2-3 ft.
sparks).

After development have a local Kokak center scan your negs to CD-ROM and
then you can pull them up for inclusion in your favorite word processors or
color printers.  BTW, if you want an incredible 6 color printer for under
$250 then pick up the Epson Stylus Photo printer -- it is so good you won't
be able to tell the difference between real photos and photos printed on
this printer.

Regards,

Dr.Resonance
