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.

Honestly, if consuming more than two Brazil nuts per day were dangerous, Belém residents would die young (and they don't).
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.

Scan of selenium toned print. My photoshop skills just aren't up to my darkroom when it comes to b&w. All my other posts thus far have been scans from negatives/slides but this scan from my print, though 3rd gen, is better than what I've been able to get out of my digital editing.

The image was given a mild selenium toned effect during processing.
Mamiya 7ii, Mamiya 43mm f/4.5L, Orange filter, Shanghai GP3. XTOL 1:1 - negative printed on FB Warmtome paper and Selenium toned - this is all detail for my geeksome pleasure and you may forget it entirely.
Firstly, the darkroom is going very well. It is an immensely peaceful activity, very difficult and very time consuming. I revel in it. Please find a scan of a print which doesn't do justice to what is probably a middling sort of print. I am still coming to terms with photographs being physical objects. I've just made the step up to fibre based paper. The photograph becomes a weighty thing.
The tone seems impossible to get right with a scan though.
Secondly, oh dear, what were Yahoo thinking. You think they might have asked a few people. I ask you - how are you supposed to present your sets to people. They aren't going to go looking are they? And the black/white thing is quite visually jarring - the lightbox was fine before when you wanted to do that sort of thing. Tsk. I will be paying 50 bucks a year to get stats? Faaack. Anyway, I won't be going anywhere else but with my beloved Google Reader kicked into touch, it is difficult not to feel like the star's tennis balls innit.
