2.4 National variation
Relatively little research has been undertaken by photohistorians in the field of domestic photography. However, we should be aware that photography developed in different ways in different countries. So, for example, in Britain the daguerreotype remained a luxury article, as high prices restricted sales to the comfortable classes, whereas in America, because of early mass production techniques, studios could offer 4 daguerreotypes for 1 dollar.
Photography was, however, a European invention. Western practitioners exported not only the technology but also European traditions of portraiture.
