An important place in my photography was when I began to feel that I was finding my own voice, that I was making the pictures that I was meant to make. It was not a "moment" as the OP suggested, or some kind of sudden epiphany. For me, it was more of an understanding that occurred over a period of time. In fact, I don't think it is over yet. I think that my way of seeing the world is still developing and being refined within me.
