Yes, I have a piece of Tech Pan that the density was measured. These days
I use the light meter in my OM-3 camera body which is calibrated in 0.1
steps. I tested the meter by holding a known neutral density filter in front
of the 50mm lens and reading the decrease on the meter. It was a 0.6 filter
and the meter went down 6 steps. I also tried the piece of TP which was
measured at 0.4. The meter went down 4 steps. It's sort of crude but when
you don't have anything else it gets you close.
