Scapolite (Meionite): Fl. lilac,
bluish, and violet, SW
This page once had an overexposed, low-res
photo of a [presumably] Pb2+-activated fluorescent scapolite
from Sterling Hill. Finally, here's a
better photo; although it's a different specimen, it's from the same
galena-bearing scapolite occurrence at this locality.
Specimen size is roughly 2 1/2 inches. This
specimen came from the recent Super Digg at
Aside from the galena and cerussite in this specimen, it is visually indistinguishable from the other chalky-white, weathered scapolites that came from the Noble Pit.
used to take mineral photos with a 35 mm camera. The color
response was really good for some minerals, unpredictable for others.
It was still better than the digital cameras of the day, though. In some ways, it is still better than
today's digital cameras, but there are definitely trade-offs.
Digital cameras have an intolerably bad dynamic highlight range and
can't cope with more than 1 or 2 stops of overexposure without blowing
out the highlights. However, for fluorescent mineral photography
they're not bad. Most of my fluorescent mineral photography is
digital today, although I have a box of slides I did recently of some
fluorescent specimens. I think it was Elite Chrome Extra Color,
but offhand I can't remember.
The newer digital cameras still don't
capture fluorescent colors perfectly, but this photo shows the subtle
hues much better than did the old one. Digital camera technology
has certainly improved
in the past few years.
(I still prefer film for most everything else.)
