Create a fully underwater scene in deep water, with no water surface or reflections. Capture four to five juvenile Formosan salmon (Oncorhynchus masou formosanus) swimming with a low-angle upward shot from the riverbed. Their small and subtly colored bodies should be visible, showcasing ultra-realistic fish scales and textures. Illuminate the scene with soft underwater lighting filtered through the deep water, with the riverbed featuring stones, pebbles, and submerged plants. Use an cinematic depth of field for high detail, capturing a serene yet lively underwater atmosphere where the fish interact naturally.
