Building upon this notion of play, my thought —
We as photographers are essentially over-grown children.
There is no pragmatic or ‘practical’ use of photography, especially when it comes to artistic matters. Thus, don’t think about the economics of photography too much. Instead, think of your art and photography as a form of play and creative self-expression:
Composition as our photographic technique, to play!
If your photography ain’t fun or playful, it isn’t worth doing.
