Hyper-réaliste photo macro d'iris fusionné

Shot with a 100mm macro lens, in 4K resolution, at a 1:1 ratio, a hyper-realistic human eye iris. Only the iris should be in the frame; no eyelid, eyelashes, or white part (sclera) should be visible. The background is completely black, with deep shadow. The iris should appear as a single eye, but it must be composed of a blend of two different people's irises: the left half of the iris should belong to the person in the first reference photo, and the right half should belong to the person in the second reference photo. Each half must faithfully preserve the iris patterns, radial lines, textures, color transitions, and unique details from its respective reference. The two halves should merge naturally and smoothly in the center. There should be no sharp line, but an organic and realistic transition. No artificial appearance, repeating patterns, or stylization whatsoever. Lighting should be like real macro photography. The iris texture should be extremely sharp, with micro-details visible, and a slight corneal reflection present. The image must be entirely photorealistic, perceived as a real photograph, not a render.
