A new era began in 1922, when Rosenberg was published for the first time in the Swedish Touring Club’s (STF) yearbook. That year’s issue had Stockholm as its theme and Rosenberg was presented on a large scale, with a city documentation of Stockholm comprising a total of 64 pages. This presented Stockholm in lyrical tones as a Sunday city, embraced by quiet and peacefulness. STF was formed at the end of the nineteenth century, with the motto ”Get to know your country” and the goal of spreading awareness of Sweden’s countryside and culture. The Club’s yearbook focused on one subject at a time. This could be about various periods in Swedish history, the shifting landscape from north to south or areas of cultural and historical value. With C. G.Rosenberg’s involvement as the principal photographer, the popular yearbook, which had an enormous circulation, developed to become one of the most important sources of the time for encouraging knowledge of photography as an art form in its own right. The inter-war years, with the refinement of 1920s classicism and radical functionalism of the 1930s, became an important period for the development of Swedish architecture. Demanding and strictly quality-aware architects, such as Gunnar Asplund, Ivar Tengbom och Ragnar Östberg, had high levels of requirements that extended to the buildings’ furnishings and decor. This was an area in which Rosenberg also received a privileged assignment, that of documenting the finished constructions on behalf of the exacting corps of architects. These architects were impressed by Rosenberg’s distinct qualities as an impartial interpreter, with a sensitive observance of the architecture’s volumes, nuances and light. Despite high demands, Rosenberg’s book production was extensive. Over a period of thirty years, he came to document Swedish architecture, industry and landscapes in more than 60 volumes, in addition to his work for STF. An example of these is ”Svenska Trädgårdskonsten” (Swedish Garden Art), a documentation of the gardens of palaces and mansions, from 1930 to 1931. The book, a double volume, was published as a small, numbered issue, with a generous folio format, beautifully designed and presented in exquisite photogravure. On the whole, C. G. Rosenberg’s photography was characterized by cool elegance, which, combined with a poetic form of documentation, makes him one of the really great Swedish photographers.
