Start with a place made for passing through. Then look for a moment when its usual activity has fallen away.
A corridor connects rooms. A waiting area exists because someone will arrive. A covered walkway takes you somewhere else. When those places are quiet, the purpose remains visible but the expected people are absent. That gap gives you a useful photographic question: what happens here when nothing is happening?
In this guide, “liminal” is a way of reading a frame: a familiar environment caught between uses, destinations or moments. An empty room alone is not a recipe. The image needs something to hold your attention: a light left on, a rhythm of doors, a chair facing nowhere, or a view that stops before it resolves.
You do not need darkness or a horror reference. Soft daylight can make an ordinary place feel just as unsettled. Begin with what is actually there.
