"A highly realistic photograph of a clear mountain river flowing through a dense pine forest. The sunlight sparkles on the water, casting shimmering reflections. In the background, a sharp, towering granite mountain rises against a bright blue sky dotted with soft, white clouds. The scene is peaceful and untouched, with detailed textures of rocks, moss, and vibrant green bushes along the riverbank. The overall atmosphere is crisp, fresh, and serene. Shot in ultra-high resolution with natural lighting, realistic colors, and depth of field."
