A good friend of mine has shown me an imposing photograph of his great grandmother, her brother, and their mother (his great-great grandmother), which he tells me was taken in the Bohemian city of Liberec (Reichenberg ) in 1915. It bears the inscription “K.u.K. Hof- u. Erzh. Kammerphotograph Carl G. Springer”. I am surprised, first of all, that a photographer so far from the capital could claim to enjoy the patronage of the King-Emperor. But my question is: what is a Kammerphotograph?
