Fatal illness has always been viewed as a test of moral character, but in the nineteenth century there is a great reluctance to let anybody flunk the test.
Our very sense of situation is now articulated by the camera's interventions. The omnipresence of cameras persuasively suggests that time consists of interesting events, events worth photographing. This, in turn, makes it easy to feel that any event, once underway, and whatever its moral character, should be allowed to complete itself - so that something else can be brought into the world, the photograph.
