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
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 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).

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 ^_^

Slightly unusual in having a concentric circle pattern on the cell window, rather than the conventional honeycomb .
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!

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!

All prints developed in rather used Ilford warmtone developer and 2 bath fixed to eliminate toning stains.
Tmax 400 film, shot at iso 800, developed in Tmax dev.
I decided to use selenium to create a blue tone on this one to bring out the tonality of this ignition image. Thoughts welcome.

Here's a photo from 18 June 2014, when Collings Foundation brought their B-17, B-24 and P-51 to Skagit Regional Airport. My photoset is here.
Metrovick selenium light meter, made in Manchester by Metropolitan Vickers - a company better known for heavier engineering, such as railway rolling stock, guns and aircraft. They made these (apparently) from 1938 until at least 1947. The dial reads shutter speeds for an aperture of f8 and 23° Scheiner film (it says so in the corners of the dial). It's small - the face is about 49x45mm (less than 2 inches). The calculator for other film speeds and apertures is heavy brass, and slots into the cover of the leather case (or, in mine, falls out of the case as the stitching is worn).
3/4-rear view of “selenium*” rectifier lamphouse power supply for the RCA Arc 400 carbon-arc 16mm movie projector, showing the AC input, pilot light, and DC output.
*That's what the specification plate says; a peek through the grille with a flashlight reveals this unit 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.

Sekonic Auto-Lumi L162 selenium cell light meter, used by the photographer to set exposure on 6 of his cameras (which either don't have LM's or don't have working LM's) and to check the light meters on the cameras that have them! This model was the first light meter used by me, but a different sample than his first one. (...which was lost, stolen, or died; I don't remember which!) Yellow tape measure is in inches. Taken in Albany, CA by a Nikon D40x with a Nikon 18-55mm non-VR kit lens. (at 55) Camera's on-board flash fired.
The meter has three modes: bright light (as seen), reduced light (what the dial is set for... the little lid on the front opens up) and dim light. (which has the reduced light lid up, and a booster pops down from the bottom of the meter... which doesn't work on this sample, as the booster doesn't release.)
Meter is set for the film speed most used by me, particularly in medium-format cameras with lenses in the ƒ 3.5 range! (ASA is the same as ISO, for newer photographers out there...)
The red dial is for use with a movie camera, and is the reverse of the black still camera dial - in the still camera's area, the shutter speeds move with the match needle; on the movie camera the f-stop moves...
I'm not sure why this light meter goes all the way to ƒ 1, as only one lens (the Canon 50mm ƒ 0.95, only available for the Canon 7 rangefinder...) had even come close to that figure, at the time this meter was in production! (1969-72...)
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...

This picture is a reminder that not everybody has somewhere warm to go home to each night, and not everybody who's cold and alone is merely an inconvenience to the rest of us.
Blind Willie Johnson was a singer and guitar player early in the 20th century. He died penniless and alone of pneumonia in the burned out ruins of his house covered in wet newspaper, but his music was chosen to go on the Golden Disc attached to the Voyager spacecraft.
His music is has traveled further than any other man-made object, and lives on.

Next print in the series. The original print colour was much the same as for 'theme', so I split-toned this in selenium and finished it in gold toner.
