Metrawatt Leica-METER MC.
Ok, now let's see if we can reach the Selenium Cell.
Start by removing this screw (see red arrow).
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.
The palace on Peacock Island, near Berlin, built by Friedrich Wilhelm II at the end of the 18th century.

Selenium light meter with incident-light "invercone" attachment. Has two ranges, the low one selected by opening a mask on the back which allows more light onto the cell, and shifts the scale to a 0-10 range.
Unfortunately the measurement switch does not work on this one, but I think the selenium cell is OK, so it may be fixable.

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.

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.

More often than not, when I find a Petri camera, it's broken. Amazingly, I found this one in working condition, including the selenium cell meter. There are many examples of the 7 S available in thrift stores and online as Petri made this particular model for over a decade. A pleasant, clean industrial design worthy of a spot on my shelves.

One of the prom photos I did for my god-daughter. Selenium tone was done in Adobe Lightroom, added Vette logo tattoo in Photoshop.
I received an email from a gentleman who was disposing of his late father's estate. He didn't want his dad's Ricoh rangefinder to end up at a thrift store or auctioned online. He offered it to me as long as I would take care good of it. I agreed and said I would be proud to display it.
What arrived was a whole kit: camera, Konica meter, Ricoh bulb flash, filters, lens hood, leather camera case and all instructions. The camera itself is in very fine condition. The focusing ring is very stiff, stuck actually. No doubt the result of the original lubricant decaying to glue over the many decades. I will certainly attend to that and return the camera to its full glory.
Taken with the Ilford Obscura Pinhole camera, with delta 100 developed in HC-110b, and then contact printed on Ilford Multigrade IV matte paper and selenium toned.
Complete with dust! Bloody dust, I can't seem to get rid of it!
Zeiss Ikon Vintage Test Lightmeters.
An retired repairman told me that these selenium cell powered lightmeters were used to check other "normal" lightmeters. That's all i know.
These meters clearly use the housing of the "normal" Ikophot model which was produced in the middle of the nineteen-fifthies.
Only adoptions seem to be the removal of the Dials and the use of another Scale.
The readings of both meters are about the same which is not bad for selenium lightmeters more then fifty years old
Why one is numbered 33 and the other 34 i don't know. Maybe serial numbers ?

Stanleya is a genus of six species of plants in the mustard family known commonly as prince's plumes. These are herbs or erect shrubs which bear dense, plumelike inflorescences of white to bright yellow flowers with long stamens. Stanleya species are native to the western United States. These plants are toxic because they concentrate selenium from the soil in their tissues.
Selenium cell was broken!..
