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.
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.

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.
2 Viewfinder modules for the Zeiss Ikon Tenax Automatic. This module also houses the Selenium lightcell.
Produced about 1960.

Complete with dust! Bloody dust, I can't seem to get rid of it!
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.

These naturally sweet Brazil Nuts are high in protein, calcium, iron, zinc, and are also a good source of selenium. They are good for snacking, cooking and baking
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.

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.

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 ?
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.

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.
Once upon a time – well, more than half a century ago – I used this Weston Master III light meter, powered by a selenium photocell, to help me when I took some of my first photographs. It was the most important aide to creating a decent exposure – but discovering it in the back of a cupboard today, I've completely forgotten how to use it. I mean... for an innumerate guy like me, look at all those dials and numbers! Anyway, here it is... a little piece of photographic history.
And this is the Ilford camera I used with it...
