What on earth is the past? While looking at these dry plate photographs, you will realise that you hover between the present and the distant past of each place at the same time. You will sense the past as if you know the past. However, you have never actually experienced those pasts. In other words, the past exists in our brain as the future does. These dry plate photographs describe that the past is not something to stream to the present. It is something to be improvised for the present on each occasion.
