        This may be because the prints were stacked, all scanned together,
and the scan not adjusted in any way so as not to complicate matters.
I'm hoping that the contrast can be evened out, or I may try something
else. The core of the situation is that the electric supply here is hard on
tungsten bulbs. It used to be a continual chore to replace lamps in the
exit signs until a source of 135 volt lamps that would fit most of them
turned up. But those are just 15 watt or so. Interesting to learn of cold
light filter sets, never have seen them in catalogs.
