In a bright blue and neon green background, a cool female Asian marathon runner is captured in sleek sportswear in a full-body shot, with colorful dynamic speed light showcasing a modern and energetic vibe as she sprints quickly. Capture dynamic running action shots in low-light conditions using a Sony A7S III camera with a 50mm f/1.4 lens. Utilize the camera's high ISO capabilities to maximize light sensitivity, engage the 5-axis in-body image stabilization to minimize camera shake, and select a fast shutter speed to freeze the motion. Employ continuous autofocus to track the runner's movement and maintain sharp focus. Take advantage of the large aperture of the 50mm lens to let in more light and create a beautiful bokeh effect, highlighting the subject against the background. Adjust exposure compensation as needed to adapt to varying light conditions, and consider shooting in RAW format for greater post-processing flexibility. Aim for a composition that conveys the energy and motion of the run, with the runner sharply in focus against a blurred, yet visually appealing, background.
