After all of the discussion about my cheap, misguided effort to determine film speed, I checked E-Bay as I do every lunch hour. Lo and behold, there was a Beseler PM2M "analog densitometer" being offered with a minimum bid of $60 and no bidders yet. Loer and beholder, two hours later, it was mine!
Now, the question remains: Can it do what I want it to do? Can it tell me if I've got a density of 0.11 over film base and fog?
Rob, who has a whole bunch of stuff waiting to be put out on E-Bay. Anybody want a Rodenstock Rodagon 135-mm f5.6 lens? New style, immaculate glass, very slight dent in the filter ring.
