The Canadian photographer William Notman and his empire of photographic studios, initiated in 1856, are the focus of this study by Stanley Triggs. Over a period of 78 years, more than 400,000 photographs were taken by the Montreal studio alone, and Triggs presents a fascinating and detailed picture of how this was achieved. Previous publications about Notman and his work are no longer in print, making William Notman's Studio a particularly valuable exposition of Canadian iconographic images.
This is a good place to start if you are new to Notman, the legendary photographer of Montreal persons, buildings and other infrastructure of pre and post Confederation Canada. Of special interest was the technical information about Notman's studio, especially the way he exploited available light.
