Read the water,
without rushing.
Stop at a safe, level spot on the path. Let your eyes settle on one small patch of water. Broad ripples often travel with the wind; a sudden ring may mark an insect, a falling leaf, or something moving below. A pattern is a clue, not a certain identification.
Compare the open surface with the sheltered edge. Reflections appear sharper where the water is calmer. Watch how a cloud changes the colours without changing the scene. Spend a minute looking before reaching for a camera; you may notice details that a wide photograph misses.
A two-minute exercise
Find one thing moving quickly, one moving slowly, and one that seems still. Describe each with a verb: drifting, trembling, circling. Then look again. Your first impression may change.
