a dash of flash<\/p><\/div>\n

Toronto<\/strong>. Post WW2, many folk investigated ways to improve flash by incorporating Edgerton’s “Speed-light” concepts in a smaller container to allow electronic flash to compete with and eventually replace flash powder, bulbs, etc.<\/p>\n

Jim Miller of Downsview (now part of Toronto) tinkered with this new means of light as early as 1946. In issue 23-3 Ev Roseborough reports Jim’s involvement in an early flash called “Trion”.<\/p>\n

Ev’s article, “Trion <\/span>\u2013 an early Canadian designed flash<\/em>“, begins, “Now tending his grapevines lovingly and expertly caning his furniture, is retired geophysicist Jim Miller of Downsview, Ontario.

“A\u00a0quick check through the photo annuals showed an ad\u00a0for the ‘Dawe’ Photoflash in the BJA of 1948. Ned\u00a0Eisenstat of Toronto manufactured\u00a0his Speedstrob in January 1948, but had been using speedlights of\u00a0different kinds since 1940. So\u00a0Miller was certainly a pioneer in\u00a0his miniaturization efforts in \u201846.” …<\/p>\n
