A calm river runs through a historic Vietnamese old town at blue hour, its dark water covered with glowing floating paper lanterns while a small wooden rowboat carrying lanterns glides in the foreground. Along the LEFT bank stands a row of yellow ochre two-story shophouses with dark wooden shutters and terracotta tile roofs, with a long riverside promenade and low stone river wall in front, cafe tables, and a few small people strolling; strings of round glowing silk lanterns in red, orange, and yellow hang along the shopfront eaves. In the center background, a wooden arched footbridge with a small tiled pagoda-style roof pavilion at its top spans the river, lit by lanterns, its arch reflected in the water. On the far RIGHT bank, more low buildings with a line of lanterns along the far promenade. Many small square paper lanterns glowing red, orange, yellow, and white float on the calm water, spread from the foreground left all the way to the bridge, each with a long shimmering reflection. In the right-center foreground, a narrow dark wooden rowboat lies diagonally, its left end lower and closer to the camera; one rower in a white conical hat and dark clothes sits at the right end holding a long wooden oar that reaches down into the water toward the lower right, and the middle of the boat carries a pile of about ten glowing paper lanterns. Deep blue twilight sky with a soft pink-violet glow on the horizon behind the bridge, no stars and no moon. Warm lantern light against cool blue dusk, photoreal cinematic travel photography, calm and magical mood. Wide landscape 16:9. No close-up faces, no text, no signs, no logos.
