The SEI Photometer
A Legend Among Spot Meters
Few people realize that photographic
spot meters date back some 2/3 of a century. The very first was built
by Arthur Dalladay, editor of The British Journal of Photography, in about
1935; he described it in the BJP Almanac of 1937 on pages 127-138. This
meter still exists, in the possession of a subsequent editor of the Journal.
Within a decade or so, there appeared two commercial meters based on the
same principle. One was the "Ainger Hall" meter, manufactured
initially by the Bowen Instrument Company and then later (to special order
only) by one of its inventors, W.G.H. Turl. The other, with numerous refinements,
was the SEI (Salford Electrical Instruments) Photometer. By 1948 the SEI
Photometer was being distributed by Ilford Ltd. and (in the U.S.A.) by
The Zoomar Corporation. Making Readings |
