Fuji Neopan 400, dev Rodinal, split grade printed on Forte FB, cold tone print dev, selenium toned, scanned Print. MamiyaRB67, 80mm.
An overview of the different silver painted faces of the Metrophot and Metraphot exposure meters that were produced by Metrawatt around 1933. The model in the middle of the bottom row, the Metraphot 16, has a larger body than the other ones because a stronger(=larger) magnet had been used. Side view.
The IIIc's built-in selenium cells lightmeter under the metal flap works well in either closed position shown here with light entering through the center hole in bright conditions or with the flap open for low light metering. But the flash-shoe mounted Kodalux L lightmeter that works on the same principle is a neat little accessory with a built-in incident light diffusor that rolls in front of the cells like a blind. Neither lightmeter needs batteries and nor does the camera which is the best part of it all.
Taken with Canon S95 in automatic focus-bracketing mode and pieced together with the Helicon Focus stacking software.
Koden Lightmeter.
Selenium lightmeter produced in Japan. My guess somewhere in the 1950's or 1960's.

Koden Lightmeter.
Selenium lightmeter produced in Japan. My guess somewhere in the 1950's or 1960's.
Inside view.
Basic selenium meter from, I guess, the 1970s. Still works well.
It's a slightly odd design choice to write 1/1000 & 1/2000 as 1M and 2M, which could be misinterpreted as minutes.
Made in Japan.
Rangefinder Kiev 4 (KNEB subtype 2a) (sn# 5922914)
with Jupiter-12 35mm f/2.8 (sn #6207012)
and KMZ Universal Finder 28-135mm ("turret finder") in symmetrically reversed design for Kiev cameras (sn #001374).
Manufactured in 1959-1962 by the Arsenal factory in Kiev (Ukraine)
The selenium light meter still works and is quite accurate!
Also, only small numbers of the symmetrically reversed design of the turret finder were produced.

3/4-front view of selenium* rectifier lamphouse power supply for the RCA Arc 400 carbon-arc 16mm movie projector, showing the current control. A fan located at the base of the power supply forces air upward to cool the transformer and rectifier stack.
This nearly-60 lb. (27 kg.) chunk of mostly iron and steel outputs 30 amperes at 28 volts, or about 840 watts, when carbons are properly aligned and the current control is adjusted to achieve the specified current.
*The specification plate on the back says "selenium" but it looks like it was retrofitted with a pair of high-current silicon diodes mounted in heat sinks along with a large electrolytic capacitor to smooth the DC output.
Selenium light-cell lens detail. Field of view about 1 inch wide. Reminds me of a honeycomb.
