Create a realistic photoshoot for a woman in a black running jacket and black running shorts, paired with white socks and white Adidas running shoes. She wears black sunglasses and is walking down black textured stairs with a yellow leaf on one of the steps, capturing the essence of fall season. The scene is set outdoors during the afternoon with dimmed lighting, using a Canon EOS 1D camera and a 50mm Canon RF lens at f/1.4 aperture to emphasize her natural expression and the atmospheric details of the environment.
