In Farsi, and in Arabic, from which it was derived, the word for photography was not invented to imply a new form of writing or painting ("drawing with light"). Instead, Arab and Persian cultures opted for a word, akkâsi, which had existed long before in their poetry.
In their view, a photograph is not a representant of reality, but is its opposite. Like a mirror. Like the reality of the reflection in another's pupils, connected to the physical world through its adversity to it.
I've always considered it impossible to prove that the reality in the mirror depends on the physical reality. It could perfectly be the other way round. A mirror as a portal between a number of adverse worlds, composed into a single world in the human mind.
Couldn't photographs be gateways into the world on the other side of the mirror, or, one might even suggest, create the reality on the other side?
