Taking photographs and writing is my way of saying I was here, I saw this, I felt this, I heard this.
I write in order to express what the photo itself cannot say. A photograph of my father doesn't tell me what I thought of him, which for me is much more important than what the man looked like.
I got a lot of flak originally for writing with photographs, because the great cliche in photography is that one photograph is worth a thousand words, and photographers are usually dodo birds anyway.
