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 ?

Fundado em 13 de Junho de 1808 por d. João, Príncipe Regente na época, mais tarde d. João VI, o Jardim Botânico em seus 137 hectares, 55 abertos à visitação pública, abriga um acervo botânico da flora brasileira e exótica e um acervo histórico-cultural.
Foi intenção de d. João VI aclimatar, na área que desapropriara para a instalação de uma fábrica de pólvora para a defesa da sua Coroa, especiarias trazidas das Índias Orientais.
De jardim de Aclimatação e Real Horto, após a coroação de d. João VI como rei do Reino Unido de Portugal e Brasil, passou a chamar-se Real Jardim Botânico. Somente no Reinado de Pedro I foi aberto à visitação pública, já com o nome de Jardim Botânico.
Em 1937, foi tombado pelo Instituto do Patrimônio Histórico e Artístico Nacional, e definido pela Unesco como Reserva da Biosfera, em 1992, e como Reserva da Biosfera da Mata Atlântica, em 1999. Tem como missão "Promover, realizar e divulgar o ensino e as pesquisas técnico-científicas sobre os recursos florísticos do Brasil, visando o conhecimento e a conservação da biodiversidade, assim como a manutenção das coleções científicas sob sua responsabilidade."

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.

Yesterday, my friends and I went on a road trip, but we got a flat and sat in the car for an hour waiting for AAA. I had my camera, and took advantage of the free time.

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!

The Russian-built SLR, made by KMZ, with a 42mm screw-thread lens mount and selenium light meter - which seems to still work. A 1973 model, with the manual-stop-down Helios-44-2 58mm/f2 lens.
This photo was taken in a south-facing window on a very dull day, so the light is mainly behind the (subject) camera, and with an LED torch pointing at the lens (hence the blue tinge to the shadows).
An overview of the different silver painted faces of the Metrophot and Metraphot exposure meters that were produced by Metrawatt around 1933. The model in the middle of the bottom row, the Metraphot 16, has a larger body than the other ones because a stronger(=larger) magnet had been used. The model bottom right is the KINO model that shows the aperture #s to be used at a certain frame speed, to be set at the back. Front view.
PMC Automatc Rapid, half format camera with Agfa's Rapid cassette system and Selenium exposure meter.
It is based on the Ricoh-EE Rapid Half. The Ricoh looks much more elegant, it hasn't the accessory shoe, the automatic/f-stop ring is directly around the lens and it hasn't this leatherette on the front.
PMC is not the company founded by Henry Reichenbach, but stands for "Premie van de Maand Club", as I learned on this helpful side. The camera was rebadged by the Dutch grocer Albert Heijn.
The camera works like its forerunners, the Ricoh Auto Half series. Fixfocus lens with 4 elements, in A-mode the shutter speed is fixed 1/125 s and the f-Stop is set automatically, a "shutter speed priority automatic" with one shutter speed, so to say. For flash photography an f-stop can be set manually, then the shutter speed is 1/30 s.
The Selenium cell isn't completely dead, but seems to be a bit weak. In the film chamber is a needle which detects the film speed from the rapid cassette. Perhaps I can fool this needle and set it to 50 ASA while using a 400 ASA film, e.g.

Best viewed large on black.
Socalcos negros (black ledgers) in the Douro region, land of the famous Porto whine vineyards and UNESCO world heritage.
Aside from the characteristic patterns, the black soil attracted my interest as usually Douro's vineyards are implanted in brownish schist terrains. Unfortunately, not even a Wratten #21 orange filter was able to cope with the haze existing that day and the light was still harsh. I need to return to such place one of those days.
Thanks for Viewing!

This is a two-range selenium meter built in a Bakelite body with a metal plate on the front for the calculator, marked for film speed in ° Scheiner and /10 DIN.
This is not marked with any names apart from a small S in the bottom-left of the scale, but I'm guessing it's one of the variants of the Gossen Ombrux 2. The Ombrux 2 was introduced in c.1939; this guess and date is based on www.myphotoweb.com by E. van der Aa..
Anyone identify it more reliably?
There's some life in the cell when you press the low-range button, but very little on the standard range.
I'd forgotten I'd taken this back last August, but was reminded whilst looking at other meter pics today.
Agfa Optima 200 Sensor ~1969
Agfa Color-Apotar 42mm, 1:2.8 Paratic lens
Auto exposure controlled by a selenium cell, big window on the top left. The system is the needle catch type.
Zone focus on top of the focus ring. Scale focus, in meters and feet in the bottom of the ring.
The advance lever is located under the camera and doubles the function as rewind lever, when the small button, bottom left of the lens is pressed and pushed towards the lens.
Made in Germany.
This camera was a gift from Hugo Cardoso, with a bunch of others.
With some lighter fluid and elbow grease 's back to life.
Thank you Hugo.

Very compact battery-less meter from the early 1960's. A reflective type, you could add an aluminum hood and perform incident light readings as well. This example is inoperative. That doesn't mean the meter cell is bad. Quite often, the wiring to the cell has weakened or corroded over time. No plans to repair, it's an elegant shelf-rider from now on.

Very simple meter with a little gem of a leather case. On the back there's a table to choose film and shutter speeds. That's about it. You turn the dial on the front until you match the needle with the scale.
This meter has a dead selenium cell or corroded wiring. Very common with meters this old. So what? It's a great looking meter that will go nicely with some of my old Argus cameras on display.
If you have more interest in old light meters, James Ollinger has a great web site full of information:
