Which was the first war in which photography was employed?

Question

Undoubtedly photography has greatly changed public perception of war; but there is no _clear point_ in which photography began to be used—whether for documenting war or anything else. So I’m left wondering, in which war was photography first used to document?

Answer 1

There is a clear point, and it is the Civil War. Look up Matthew Brady. He (and his crews) took field view cameras out onto the battlefields after a battle and photographed the death and destruction left behind.
