[Leica] day-for-night photography

[pklein at 2alpha.net (Peter Klein)]

I'll bet they used a monochromatic DFN filter in many scenes from one of my 
guilty pleasures:  the original Perry Mason TV series.  No not the specials 
from the 1980s where Raymond Burr was fat and had a beard.  I'm talking 
about the episodes from 1950s and early 1960s that were shot on B&W film.

Every other episode had this stock scene where Burr would be summoned to a 
client's aid late at night, only to discover a dead body.  It would look 
almost like night, but not quite right if you paid close attention.  And 
then he would pick up a phone with a handkerchief, and say, "Della, listen 
very carefully.  I want you to wait 15 minutes, then call Lt. Tragg.  Tell 
him to meet me up at the old Collins place..."
