Densitometers are as useful as light meters. Once youj get the hang of
them, they offer irreplaceable understanding that can make your DR work go
very quickly.
I first take the reading of the negative of the base + fog, subtract that
from the D-Min, subtract that from the D-Max and get the minimum Range for
the contrast range or grade of paper of most optimum.
After all this, the first time; I got to understand which negative required
which paper grade and it all clicked. It ran over into the Pt/Pd work I was
doing so that I could 'nail' the times every print I made.
I did small production, and it ran like a 1000 print a day one hour pro lab.
No too useless in my opinion.

I dare not speak it's name lest it bringeth bad luck on all of ye.
However, just for a laugh, I bought an RD 100R at a swap meet on the
weekend. It looks like it's in good condition, although I think I might
just place it on a shelf as a curio in the darkroom. (Do I dare switch it
on?)
Does anyone know what these things cost when they were new? And when
exactly that was?
