      If the green is dark enough, you can expose it to regular
      orthochromatic film. However if it is lighter, you will need to
      use panchromatic film and expose through a red filter.

      Pagan, Pagan, what are you finding?
      Yours is the road that winds lonely and far,
      Strange are the shadows that round you come creeping,
      Still through the clouds is the glint of a star!
