Winter Rainbow over Niagara Falls in Daylight

Photorealistic winter panorama of Niagara Falls in bright daylight. Snow blankets surrounding cliffs and pine trees. Ice forms along the riverbank and on viewing railings. The massive falls roar and spray into a mist that catches the sunlight, creating a vivid rainbow arcing across the mist. Rainbow colors should be saturated from red to violet, contrasting with cool blues and whites of ice and snow. A clear blue sky overhead, sun high and angled, casting crisp highlights on ice crystals in the foreground. The scene uses a wide-angle perspective to emphasize the falls' scale and the distant gorge. Include fine textures: translucent ice, rough rock faces, sparkling water droplets, frost on branches. Subtle silhouettes of visitors in winter clothing can convey scale without clutter. Render in high dynamic range with ultra-detailed textures, aiming for 8K realism, with a shallow depth of field in the foreground ice and deep, expansive background.
