Has anyone read it? It's about the sociology of photography written in the 1960s.

>The everyday practice of photography by millions of amateur photographers may seem to be a spontaneous and highly personal activity. But France's leading sociologist and cultural theorist Pierre Bourdieu and his research associates show that few cultural activities are more structural and systematic than photography.

Based on comments few things it tells are that lower class people are more photography gear and rigid technique oriented and upper class people treat photography more as an art.
And most successful professional photographers come from upper class because it's still a business and they get a head start with money and connections. Even though photographers are commonly thought as self made as it isn't a conventional career.

>It is no accident that passionate photographers are always obliged to develop the aesthetic theory of their practice, to justify their existence as photographers by justifying the existence of photography as a true art.
