Correct. =  I started darkroom work in 1964, and from the beginning we
used amber safelights.  I don't think red safelights = have been used
since long before that.

When I learned film photography = in the mid 1980s the darkroom had
red lights.  Of = course it was a very old darkroom in a middle school,

Hmm.  Any idea how old the = equipment is?  I suppose you wouldn't
expect people = to replace existing, functional equipment without good
reason.
