Sometimes good photos are found, made, or accidentally created.
Found: the driftwood on a barren but unkempt beach and a lifeless sky.
Made: the idea to use a model to mirror the driftwood, brown dress and all
Accidentally created: the necessary overexposure to wash out the sky (which would have served as a distraction to your inspiration) and the very fine mist on the camera lens, which created a very subtle polka-dot effect which I don't think could have been duplicated in Photoshop
But I'm wondering: would the mimicry been more effective if the model was the one in the background? The human form is more easily assumed when seen in the distance, but if you didn't tell me that was driftwood, I would have never known. A closeup of that would clarify to the viewer exactly what it was, then they would a notice a similar object in the background, except, no, it's a woman in a brown dress.
I'm from the old-school where the viewer shouldn't need to be "guided" to figuring out what he sees.
This is an excellent piece and a powerful inspiration!
