Fuji Neopan 400, dev Rodinal, split grade printed on Forte FB, cold tone print dev, selenium toned, scanned Print. MamiyaRB67, 80mm.
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.
Mamiya Elca with built-in selenium meter. The first Japanese camera with a match needle exposuremeter. On top of the camera provisions to connect a booster cell, originally made by Sekonic for their Sekonic L8 exposure meter. Lens Sekor 2.8/50mm. 1958

A selenium meter coupled directly to the lens aperture ring is an interesting, if ungainly-looking, solution. The Schneider version seems to be a twin of the one offered on Isco lenses (a sister company).
The "Stop-O-Matic" series are specific to Exakta SLRs, as can be seen by the shutter release to the left of the focus & aperture index. Internal stopdown coupling is clearly the way forward and Schneider is now also offering "automatic diaphragm" lenses with that feature.
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.

Koden Lightmeter.
Selenium lightmeter produced in Japan. My guess somewhere in the 1950's or 1960's.

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.

A (metal) cigarbox full of selenium cells for light meters. One has a date stamp on it from 1938 !
Guess i have now enough of these cells for the next decade :-)
One of my first series of photos that I shot solely for the purpose of making a print series. They were originally shot on a rather nice early Saturday morning drive in August of 2014 through the Cleveland Flats and Industry Valley sections of the city.
The title comes from a specific bend in the Cuyahoga River in the Cleveland Flats that was notorious for a lot of collisions between ships navigating the river through the former industrial hotbed of the city.

Selenium match-needle light meter, c.1961. Bakelite-type plastic case with metal discs on the calculator. Marked in GOST (ГОСТ), with a conversion table for ASA and DIN on the back.
Slightly unusually, the scale has bright on the left and dim on the right (as though it was designed to be held the other way up).

The 'Edmund Gardner', berthed in Canning Graving Dock, Liverpool, England. Original image digitally selenium toned prior to being printed on high-quality glossy paper. Then manually overpainted with acrylic paint. The image depicts the former Liverpool pilot ship pictured in its original livery in 2013. The following year the vessel was chosen to be painted as a 'Dazzle' ship - in homage to the camouflage of ships in the First World War.
