I'm going to Boston next month. One day, to see all I can see of these exhibits. The list is remarkable! I am looking forward to this in particular: The invention of photography in 1839 was a pivotal achievement that changed the course of cultural history. The early years of the medium were rich in experimentation. As each process and technique was invented, artists enthusiastically explored new possibilities for visual recording and expression. This exhibition celebrates the golden age of early photography in France and Britain, the two countries in which the medium was simultaneously invented.
