If a tree falls…

I really enjoyed these last reading as they spoke to my passion of film and photography from a unique perspective. In Susan Sontag, On Photography, she opens by stating “Reality has always been interpreted through images…”. I found this similar to the philosophy question ‘if a tress falls in the rain forest and no one is around to see it, does it make a sound.  Image, spectacle, and cinematic are intertwined and interdependent on one another.  Images must have an audience and images are a part of the culture that audiences create. The defining point is the message these images, or I could say art, portray. Like the tree, if someone takes a picture, and no one ever sees it, does it constitute as art? What would it express?
