On walking the same road twice
The second time down any road is when you actually see it. The first pass you're navigating; the second pass you're noticing. Most of the photographs here are from second passes.
The ten-minute window
Good light doesn't wait, but it does warn you. The trick is being already outside when it happens — which mostly means being outside a lot when nothing is happening.
What people walk past
It's rarely hidden. It's usually in plain sight at the edge of a parking lot, and the only thing it asks of you is thirty seconds of attention.
