Let's try some non-content related things...

The anticipation time between exposure and development.
The unmistakable smell of a mid-life acid fixing bath.
The quiet gurgling sound of the siphon hose on a print washer.
The comforting appearance of anything viewed under red light.

The assumption that it must be about terrorism.
The assumption that is must be about kiddie porn.
The assumption that newer is always better.
The assumption that he must be a moron to want to photograph THAT!
