Notman established his first photography studio in Montreal in 1856 and relentlessly expanded his operations over the next two decades. At its peak, his company had twenty-four branches throughout Canada and New England, making it the most successful photographic enterprise in North America at the time. Notman specialized in composite portraits of large groups, including sporting clubs, trade associations, family gatherings, clergymen, and college graduates, some featuring more than four hundred figures. Each figure in a group was photographed separately in the studio then printed at the proper scale and pasted onto a painted background, as in this portrait of a Nova Scotia snowshoe club. The entire collage was then re-photographed. The final, relatively seamless tableau could then be printed and sold in a variety of sizes and formats.
