Is this a "good" photograph? It exists - therefore it IS. Does it have an equal amount of significance for all? - Or are we all caught up by its emotional content? I seriously doubt either - but that can be said about every photograph or work of art from the beginning of homo sapiens (or maybe even before).

Is it really so important to know whether any or each of us consider it to be good or bad?

In any effort to evaluate any work of art, we necessarily define ourselves - far more than determining the goodness - or lack of it - in any photograph.
