Film: Kodak Royal Gold 100 or slower ISO film
5.0 neutral density filters on lens (Wratten ND 4.00 plus ND 1.00 or Wratten ND 2.00 plus ND 3.00). This is adds up to 15 stops.
Starting point: 1/125 at f/8 and bracket the hell out of it
* In 1979, I was fairly successful using 2 polarizing filters and a 4.00 ND on a very stable tripod with a 600mm lens and a 2X extender.
AVOID LOOKING INTO THE VIEWFINDER AS THIS CAN CAUSE PERMANENT RETINA DAMAGE RESULTING IN BLINDNESS. USE A RANGEFINDER OR MIRROR. AN OVEREXPOSED (BULLET PROOF) NEGATIVE OVER THE EYEPIECE WILL HELP REDUCE THE INTENSITY IF USING A MIRROR.
Any one else, with a "bright idea" on this subject, feel free to add to these suggestions or relate past experiences.
