What I like most about this scene was how the water form being sliced through by the speeding "sampan". To emphasize the fine textures of the shadow and highlights, I chose the "Film Grain" Art Filter. Indeed a wise choice!

The trail of the boat's wake can be seen across the image. The calmness of the lake stirred by the motorboats roaring blades captured brilliantly in shades of shadows and highlights.
If it was in color, I do not think it will convey the same impact!
