Toronto. In this 1949 ad from the April issue of International Photographer shows what can be done with the amazing Kodatron Speed Lamp by Kodak. Edgerton had demonstrated the use of the technology for photography a few years earlier at M.I.T.
In this ad, Kodak was addressing Hollywood and the movie crowd. The electronic flash was for professional studio illumination at the time. A heavy portable flash was available for professionals too, Amateur snappers and many professionals on the move resorted to the much cheaper one-use flash bulbs. It was after WW2 that electronic flash was finally cheap enough and portable enough to be widely used outside the studio environment.
A big thanks once again to my good friend and retired cinematographer, George Dunbar. George came across this ad while researching photographic history as denoted in both poplar and photographic magazines of last century.
