We make meaning by selecting and discarding — by editing. The more images we collectively over-produce, the more ruthless we need to be as individual viewers in bestowing our precious attention only on things that matter to us.
The unceasing production of personal photographs provides consolation for the ego, yet it is also a delusion: most of these images are hurtling toward oblivion.
