My second portfolio is out, it's called collapsed wave functions, available on Blurb both as a hardcover, and as an eBook. Here's the introduction text, that explains the reason of the title:
In some of the interpretations of quantum mechanics, the universe at very small scales doesn't have an objective reality. On those scales, reality depends on observations which collapse the wave functions that describe, in terms of probabilities, all the possible states that a particle system can have, thereby creating a single observed state.
We can use this scientific concept as a metaphor for photography: each photograph taken of a certain part of the visible universe, and its subsequent editing, sharing, observation, and interpretation, becomes an unique reality for each viewer, every time they observe that part of the universe through that certain photograph. Like an intermediate link between the visible universe and the conscious observer.
Therefore, a photograph that doesn't get shared and observed is a dead end, as it needs conscious observers to complete that link and become part of reality.
