During the journey of shooting trees, I occasionally found a special perspective: interpreting trees in the dark through black and white inversion, thus starting the entire exploration of this project. I like trees so I shoot them, but it is not easy to do it in a city with a cluttered background, and even harder in the night. However, I therefore found that if the unpopular technique of black and white inversion is applied to the trees in the dark, it might bloom such an impactful image: sometimes it can produce a sketch-like texture, sometimes it can create artistic mood like ink painting.
