Bought this from a gentleman around the corner who later turned out to be a good friend. I have no idea how this works, just what it states on the case. I don't work with selenium rectifiers much so it's basically a dust collector. As always, the day I get rid of it, I'll need it.
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).
A discarded boot that washed up on a Lake Erie beach, rendered as a selenium print.
My tribute to Edward Weston's Abandoned Shoes Alabama Hills.
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.

The original print of this 4x5 negative was a little disappointing. Some plugged shadows, a lot of muddy midtones and a featureless sky. It was suggested to me to treat with Selinium to richen the midtone. The side benefit is the selenium found some sky detail to tint, All in all I like this a lot. Vignette was added later in lightroom
Out of the case. The case has a hole at the end for the lanyard loop and a metal clip across the bottom which engages into two holes to hold the meter in - very effectively.

Selenium Toned, Silver Gelatin Print, 1995
Self portrait, and the first photograph that I ever sold. Sold at a small gallery in Rock Creek Park that was in a house. Each one is unique because it is so hard to print a super high contrast image like this consistently. That one was my favorite, so I had trouble letting go of it.
No manipulation of image here. This is Kodak TMax 3200 film pushed to 12800 (2 stops). Very hard to print but I printed with contrast in mind while still retaining some tonality.
This image is called "Sorrow" but I wonder if it should actually be called "Shame."
Side Note - this image is actually painting with light as I kept the shutter open for about 16 seconds and moved the light under my face and shoulders. I had to "imagine" how the light might look. This was film too, so was many hours before I knew how this came out.

A match-needle selenium device, c.1962.
(That's the end of Light Meter Week chez Awcam).
A color temperature meter with scales for color filter correction. Production started in 1957 with the white model, followed by the black and later the grey models.
It sound better in swedish where the word "utanförskap" (exclusion) have been a political term used by all parties when speaking, in a simplified way, about people who are unemployed, sick or everybody who is not working...

Remember, if your camera comes with selenium light meter like the Olympus Trip 35 (think Agfa Optima or Silette, certain Voigtlanders, Werras) they need to be kept in the dark or it will exhaust the cell.
Never buy one on display in a bright counter without a lens cap. The meter will most likely be on its last legs.
The camera won the 1968 Good Design award.
The Olympus write up on the camera goes:
The Olympus TRIP 35 is a full-sized compact EE camera based on the Pen EES. It first went on sale in 1968. The name reflects its suitability as a convenient camera to take on trips. The TRIP 35 became very popular as a camera that combined ease of use, reliability and a low price with superb photographic performance. It remained a best-seller for many years, and over the next 20 years over 10 million were produced.

A mineral is a naturally-occurring, solid, inorganic, crystalline substance having a fairly definite chemical composition and having fairly definite physical properties. At its simplest, a mineral is a naturally-occurring solid chemical. Currently, there are over 4900 named and described minerals - about 200 of them are common and about 20 of them are very common. Mineral classification is based on anion chemistry. Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.
Elements are fundamental substances of matter - matter that is composed of the same types of atoms. At present, 118 elements are known (four of them are still unnamed). Of these, 98 occur naturally on Earth (hydrogen to californium). Most of these occur in rocks & minerals, although some occur in very small, trace amounts. Only some elements occur in their native elemental state as minerals.
To find a native element in nature, it must be relatively non-reactive and there must be some concentration process. Metallic, semimetallic (metalloid), and nonmetallic elements are known in their native state.
The rock shown above is from a "roll front deposit", in which native selenium occurs along a redox front in fluvial sandstone (see Granger & Santos, 1982).
Stratigraphy & age of host rock: fluvial sandstone, Westwater Canyon Member, Morrison Formation, Upper Jurassic

My grandparents' old GM Model B Standard Exposure Meter. It's got a slide rule on the back for you to determine your f-stop/shutter speed. I learned from a friend today that this is, in fact, powered by Selenium! And it still works!
Note: Another neat fact: This is from around the 40s! And you can get one for, like, $20!
A cute little Russian oddity, complete with Cyrilic text. I believe this was released in around 1983, though my case is marked 1992. This would have been outdated technology when it was released in 1983. That's the Soviet Union for you...
As Murray Walker once said "It's raining and the track is wet" - It's raining today and the shed is wet, as would I be if I'd left the house. I have a man cold, as such, I wish to just mooch around feeling glum, for a change.
To brighten the day my father found some mid 20th century exposure meters, these are Selenium powered and as such require no batteries, hoorah. This CP Prixcolor has a flip over incident cover. Film speed from 12 up to 3200 ASA (ISO), shutter speeds from 1 to 1/1000th and was made in West Germany in 1977.
He found the instruction book later on ^_^

A selenium meter for mounting in the accessory shoe. Dimensions: 31mm diameter at the end of the hood, 39mm long (1 1/2 x 1 9/32 inches).
Shoe mount (foot?) is hidden on the other side.
Slightly unusual in having a concentric circle pattern on the cell window, rather than the conventional honeycomb .
I decided to use selenium to create a blue tone on this one to bring out the tonality of this ignition image. Thoughts welcome.

I can't find many (if any) reference images for before/after toning of various papers and I can't find a copy of Tim Rudman's book on toning, therefore I am creating tests and will try to publish them here for the rest of the darkroom users out there!
