Imagine you are in an art studio. In that studio a model is posing nude for a life drawing class. There are perhaps twenty or so pupils drawing the model from various angles in the particular pose the model has chosen. Each artist is a finely tuned singular instrument of perception, having lived a particular life, with particular events and having been brought up in a social environment unique to them. Each artist has their own unique tastes and forms of expression. Each produces their own image of that moment in space/time.
If the artists get up and wander around the room they can see the various views of and interpretations of the model. The artwork will say much more about the observer than the observed.
This is the truth of beauty.
