Capture a stunning close-up action shot of a vibrant kingfisher diving into the water at a serene riverbank during the golden hour. The image should showcase the kingfisher's iridescent blue and orange feathers glistening in the warm sunlight, with droplets of water splashing around as it catches a small, shimmering fish. The background should feature soft, blurred reeds and gentle ripples in the water, creating a tranquil yet dynamic atmosphere. Use a Canon EOS R5 with a 100-400mm lens, set to a fast shutter speed of 1/2000s, aperture of f/4.5 for a shallow depth of field, and ISO 400 to maintain clarity. The natural golden hour light should cast a warm glow, enhancing the colors and textures of the scene. In post-production, apply sharpening to highlight the intricate details of the feathers and the fish, ensuring the image is a breathtaking masterpiece of wildlife photography.
