Study of Eugenie von Klenze, Franz Hanfstaengl, 1854
In the 19th century, nudes were an acceptable subject if portrayed demurely enough. Photographs by definition showed real rather than imagined people, as in paintings; photographers thus had to take care to stay within decorous boundaries. As an ‘artistic study’, this photograph by Hanfstaengl is in keeping with what was customary and acceptable in art.
