A roll of film gives you thirty-six chances. No preview, no delete button, no burst mode. You wait a week to see what you actually made.
Waiting changes the way you look
With a phone I photograph everything and look at nothing. With film, I walk around a scene twice before pressing the shutter. I notice where the light falls and when someone is about to turn their head.
Three rules I keep
Never shoot the same scene twice
Leave one frame for the walk home
Write down the date and the weather
When the scans come back, the bad photos are still useful. They show me what I was paying attention to, and what I missed.
