Classic cameras prior to the 1950’s did not have exposure meters built into them. To meet this need as well as the high standards required by professional photographers, in 1945 Sangamo Weston began manufacturing highly accurate selenium celled exposure meters in the USA and in 1952 in the U.K. Production of the superb Weston Master II began in 1946 with the model number of S141/735.
The meter had two sensitivity ranges, one for bright light the other for low light. Low light sensitivity was selected by opening a perforated lid revealed more of the sensor, an action which automatically altered the light value measurement scale. Because ASA and ISO film emulsion speeds were not then established, Weston had its own emulsion speed system which later required slight alteration to be equivalent to ISO ratings.
Shown is a British made Weston resting on its Invercone (incident light measurement cone) which clipped over the sensor and dates from 1948. Weston Master II meters are almost indestructible and many are still in use today by owners of classic cameras.
Weston, the worlds most respected exposure meter.

Hasselblad, 50mm acros film, printed on Ilford warmtone, toned with selenium
As previously stated (in German) the result of Gold tonings are highly dependend on paper and developer. The warmer the print, the cooler the tone after toning. Cool developed papers don´t show an obvious colour change and not much is changed even whith extended toning times.
Adox Variotone Premium
Gold toning (MT10) 3 minutes
for comparison Selenium toning (MT1) 1+10 3 minutes
and Selenium and Gold toning each 3 minutes
After 5 minutes Gold toning (with fresh toner) there is no remaining Silver. One can test this by bleaching the toned print. No change of density and color means that all the Silver has been transferred in full to stable Gold.
Darkroom 8x10 contact print on Adox MCC paper. Split toned with selenium and sepia. A few dust spots which I haven’t spotted out yet.
I have to give credit to moosehd2 for giving me the idea of using selenium in Light Room. I saw his shot and what he had done with it and I immediately thought of this photo. This was taken with my little 3 mp PS two summers ago. It didn't turn out too shabby. But you gotta check out moosehd2's shot - it's awesome.
Sorry I'm so behind on comments. And family is in town this weekend so time here will be limited. I will catch up!! In the meantime, have a fabulous holiday weekend!!
Oh. This is a 1957 Cadillac Eldorado Brougham Hardtop Sport Sedan.
Photograph made the last day this horse, Doc, was alive. The owner knew she had to put him down the next day. Poor horse had cancer in one eye. After surgically removing that eye he was fine for six years and then developed cancer in his remaining eye, so he would be blind.
I hope the print shows just how much she loved her horse.
This 14x14" silver gelatin print will be delivered to the owner on the three year anniversary of Doc's passing.
I had to scan the print in four pieces and stitch them together, so it might look a bit uneven.

Match needle selenium light meter with a very ornate flattened chain.Presumably dates from the 1960s, but it was introduced in 1950s. This one has a Scheiner/DIN speed conversion table on the back of the meter. James Ollinger shows the similar scaled (rather than match-needle) version, dating it at 1953. Others refer to the scale model replacing the match needle model, so this one would pre-date 1953, but the Marriot's site shows it in a 1961 Zeiss catalogue, priced at £9-9s-2d.
This one works.
Looking at the picture on Flickr, the meter looks a bit whiter than it should - it ought to be a little yellower.
Paper: Kodak Portralure G 1976 (warmtone enlarging paper similar to Ektalure G)
Developer: Ansco 108 1:0 for 2 min (high contrast developer)
Toner: Moersch MT5 (Polysulfide) followed by Ilford Selenium
This is a new interpretation of this rose picture I took in 2007. The negative was underexposed and quite thin so I mixed up some Ansco 108, a high contrast developer. Portralue's contrast supposedly is grade 1-3 with the use of filters (I haven't tried this).
I have started using Moersch's MT4 polysulfide toner for the first time. It's replacing Agfa's Virdon that I briefly experimented with (and later gave up on:). The saturation becomes much greater when followed by a strong selenium bath and becomes warmer.
