A scene from a high-quality film. In a deep midsummer forest, a train speeds down tracks showered in sunlight filtering through the trees. The camera weaves through the trees, chasing the train to emphasize the sense of speed. A girl with her head out the window is bathed in the rapidly changing light and shadow, her hair fluttering in a wind that carries the scent of green. The trees in the background become a green afterimage, vividly highlighting her expression, full of liberation, from moment to moment.
