highly textured macro photography ultra-close-up of a lion's eye with evocative gaze, intense ferocity, and unbridled fury, conveying raw power and uncontainable energy through intensely realistic, photo-realistic, and highly detailed depictions of iris, pupil, and surrounding eyelid, set against a cinematic lighting backdrop with advanced perspective, imbuing the image with a seemingly four-dimensional quality of depth, rendering the subject in ultra-high detail, with photorealistic quality reaching 4k+, lens set to 1000mm, aperture f/1.4, shutter speed 1/5000s, ISO 100.
