O.K. I think that what Mark is asking is something that all of us do in one form or another, whether we realize it or not. Maybe not in a formally defined manner but still it happens.
What I mean is that for each of us, through our photography, express our view of the world...of life...the questions that remain and the awarenesses that we have gained. This faith is basically a belief that we have chosen and we express it through the actions that we take and the images that we make.
Perhaps this is not what Mark has in mind...but I wonder if perhaps the answer preceded the question.
