Publications & Further Reading:

Weston Electrical Instruments Corp., the original American manufacturer, produced a small number of publications to support the marketing of their various instruments. In developing and selling photovoltaic cell meters, they were working at the very forefront of technological innovation, worldwide.

Because of this, their customers, actual or prospective, needed technical guidance on the immediate or potential use of the products to be purchased. The photographer needed to be shown the correct way to use their new exposure meter, whatever the scene to be captured or the film stock used for the recording. The industrialist needed to have confidence in their workplace light level meters, and the engineer needed to know the capabilities of the photovoltaic cell, and its potential uses when incorporated into circuits using other Weston Components.

Comprehensive and well produced instruction manuals went a long way to fulfilling these needs but the requirement for broader documentary support remained. Weston were far-sighted in realising that their customers would also be their best salesmen if they were awakened to just what their photoelectric cell and other components could do in original systems designs.

I have included some references to other publications: Relevant articles and books that are not, as far as I am aware, available for viewing on-line. Sometimes they can be found for sale on line and would also be available from libraries. Where publications are illustrated, click on the image to download a PDF. They are print disabled and should not be distributed commercially. Other listings are for reference only.

The Photronic PhotoElectric Cell: Monograph B-8: Published by Weston Electrical Instrument Corp. New Jersey 1935. (Pt.1)

A remarkable monograph detailing the technology of the Photronic cell which lies at the heart of most of Weston's light meters. Technical descriptions, theory, applications and experiments are covered in an extensive resource document for engineers and systems designers. The monograph is presented here in 3 parts due to its length. The Author is unfortunately not credited but the extensive bibliography is included in the 3rd part. This first part has chapters on Technical History, Light Units and Concepts.

In Pursuit of Weston Light Meters: John Bunyan. Journal Abstract: Photographica World.  No160  2018/3  Ed. .James Downs

My own article published in September 2018 in Photographica World, the journal of the Photographic Collectors Club of Great Britain. The first of two, it covers the early professional meters made in New Jersey and the Master series made in America and the Sangamo factory in Enfield, Middx. UK.

In Further Pursuit of Weston Light Meters: John Bunyan. Journal Abstract: Photographica World. No 163 2019/3 Ed. James Downs

This second of my articles covers the Direct Reading (DR or Junior) range, the Leicameters and the later models comprising of the Ranger 9, the Pixie and the Japanese XM models. I must point out 2 errors highlighted by club readers (to whom I am grateful): A rarer variant of the model 650 Leicameter uses Weston Speeds, not ASA.  The Ranger 9 kit does come with an Invercone thus supporting incident light readings.
