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).
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 Æ’ 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 Æ’ 1, as only one lens (the Canon 50mm Æ’ 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...)

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.

Again, clearly somebody repaired/tampered before and obviously loved to use generous amounts of glue.

A plastic bag contained this sparepart selenium cell for the famous Olympus Pen EE camera. So must be from around 1962.

The American, selenium-cell Norwood Director was the pioneer of swivel-head exposure meters, designed to measure incident light only.
Selenium meter, with the "Color Finder" gadget on the side. Shown with the "rolltop" partly closed - this rolls round to be an incident-light diffuser if you stop at the red marks, or when fully extended, to cover the scale and close the meter.
A better-focused, wider shot of This one; in the original, I just could not persuade the auto-focus to lock on to cell. Here I can focus manually.

Rayleigh's Owl (like Rayleigh's Fish ) is made from glass containing a metal vapour that results in a 'perfect' Rayleigh scatterer. When illuminated in different ways, it can mimic the entire range of twilight colours seen in the sky. The two spectra shown here represent the transmission of light through the whole height of the owl (red line) and the scattered blue light looking sideways close to where the light beam enters the glass (blue line). These represent the setting sun and the blue sky respectively. The spectra also show absorption features due to selenium used to remove the green (iron) tint from high quality glasses.
Note that the rise in the scattering curve shoreward of ~400nm is due to uncorrected straylight in the spectrometer. At the time I made this observation, I did not know how to correct for it. Now I do (April 2015). See the comment from me below.

i was having a clear out and thought i'd try this in b&w. used my new toy (Silver Efex Pro) to add some structure and a selenium tone (with a bit of gold in the highlights). would be interesting to see if i could get the same detail straight out of the camera.

Kentmere Fineprint VC Warmtone Semi-Matt paper, developed in Ilford Multigrade 1 + 9 for 90 seconds.
The print was first toned in Harman Selenium 1+3 for 45 seconds, then fully washed, bleached to completion in Potassium Ferricyanide and toned to completion in Fotospeed Sepia.
The intended result of this split-toning was cool dark selenium lower tones with warm brown sepia highlights. What actually happened was that the selenium was too strong and toned all parts of the print which prevented the bleach from having any noticeable effect. I carried on with the sepia anyway, and after drying realised that there had been an effect after all - the print tone had lost the selenium aubergine and taken on a cold blue-black hue. Very nice, even though it does jar slightly with the cream paper base colour. I don't understand what happened, but I like it!

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).

Selenium oxidizes readily when heated on steel loop and the vapor burns in contact with aerated butane flame with a bright blue flame, turning brighter and more purplish with stronger heating, forming acidic fumes of selenium dioxide. Selenium does not continue to burn when the gas flame is removed.
