I bought this a while ago from a car boot. Initially They wanted two quid, at which I walked. A few weeks later they took 50p. However, it looked faulty. Still, came in a cute little zipped leather case!
Forgot all about it until this evening. I took it apart, bent a copper strip that pushes the selenium cell forwards, and hey ... it works! It might need some calibration though, I feel that it underexposes a wee bit, at least against the light meter in my Sony DSLR.
llford Textured Fine Art Silver Gelatine Paper
Zur exakten Ermittlung von "ISO Speed and Range" ist der Graukarten-Langweiler erforderlich. Darauf kann bei diesem Papier getrost verzichtet werden, Filterwerte und Belichtungszeiten liegen sehr nahe denen des MGWT.
Die Qualität einer Emulsion (lange Range - echte Gradation 5 oder mehr) zeigt sich bei der Tonwertdifferenzierung dünner Negative. Dieses Negativ - eine Jugendsünde, unterbelichtet und unterentwickelt - ist ohne Kopfstände "tonwertrichtig" nur zu Papier zu bringen, wenn die Emulsion mitspielt.
Die Reaktion auf Toner ist erfreulich deutlich, lediglich der Selentoner tut sich etwas schwerer, was jedoch kein Nachteil ist, wenn er lediglich zur Erhöhung der Maximalschwärzung eingesetzt werden soll. Für eine Farbveränderung aller Tonwerte (nicht nur der Schatten) wirkt natürlich auch hier eine dezente Vortonung mit Thioharnstoff.

Selenium Print
Researchers at the Pacific Northwest National Laboratory aimed to make micro- and nanostructures of selenium in a single heat-treatment. Here, a pseudo-colored scanning electron micrograph of multi-phase selenium microstructures is shown as-grown in a single experiment on a fused quartz substrate while under vacuum in a sealed glass vessel.

Found in a catch-all bag of filters and miscellaneous items purchased from a thrift store. Came with its leather case. The meter still functions and is a small wonder of construction. Thought I should document it in direct sunlight one last time. I'll keep it in its case and away from direct light; I want that selenium cell's sensitivity to last a little longer.
Wanted to try some Selenium treatment on the Bow, as I haven't played with that colour palate in a while. Originally was going to upload the B&W version, but I think this one popped a bit more.
2 Viewfinder modules for the Zeiss Ikon Tenax Automatic. This module also houses the Selenium lightcell.
Produced about 1960.

Note, I'm not trying to make a statement about the queen, the British royal family, or her position as our head of state. I simply tried to make this photo striking.

A very nice camera - shame it takes 126 film, and so seems very unlikely I'll get to use it.
It seems to be made of two polished, cast steel blocks, faced by plastic, covered with leatherette. It's very heavy and business-like. The lens collapses, to hide the shutter-speed scale, through a button in the base.
Made in Germany by Kodak AG, 1963-1966 (only available in the US for the last year). It has a coupled, Gossen-branded selenium light meter with a needle-centre display in the viewfinder - which still seems to work accurately. Compur shutter 1/30-1/500 + B, distance scale (in feet on this one) with click-stops for three distance zones - with two small pins on the rim to help grip. Schneider-Kreuznach Xenar (Tessar copy) 38mm f/2.8 lens, stopping to f/22.
Nice features such as a click-stopped stay on the film door to hold it open during loading, a short-throw (90°) advance lever set into the base at the back, worked by the right thumb, and both hot-shoe and PC flash connections.

My very first print out of a 4x5 negative, and I'm actually super happy with this one. Probably one of my favourite shots from my time at the Gettysburg battlefield as well!

Hanging about in cemeteries may not be everyone's cup of tea, but my local one has some interesting trees which justify spending some time there. The more I look at this print, the more I think the neg would have been better shot in less bright conditions. Controlling the highlights and getting the right range of tones in the print has been a bit of a struggle. Still, some selenium and gold has helped the image tremendously.
