At dusk in a tea plantation, a long-haired woman in a light-blue top walks slowly away from camera between the rows, her right hand brushing the tops of the leaves so they sway; waist-level camera follows at a constant distance, warm rim light outlining hair and shoulders, distant mountains soft in shallow depth of field.
