Create an ultra-realistic photograph of a herd of elephants in the savanna at golden hour, showcasing their majestic presence against a stunning sunset backdrop. Use a 200mm telephoto lens with an aperture of f/5.6 to capture the elephants from a distance, allowing for a close-up view of their interactions and expressions. Set the ISO to 400 and shutter speed to 1/400s to ensure clarity and freeze any movement. In the foreground, a few elephants should be playfully interacting, such as trunk entwining or gentle nudging, while the background reveals a softly blurred savanna landscape with tall grasses and distant trees. The warm light of the golden hour illuminates the elephants, highlighting the textures of their skin and the gentle curves of their bodies, while casting long shadows that add depth and drama to the scene. In post-production, apply subtle HDR techniques to enhance the colors and details, ensuring the image is vibrant and lifelike. This photograph aims to evoke feelings of awe and admiration for these magnificent creatures in their natural environment.
