Hiper-realista foto macro de íris mesclada

Captured with a 100mm macro lens, in 4K resolution, at a 1:1 ratio, a hyper-realistic human eye iris. The frame should contain only the iris, with no eyelid, eyelashes, or white part (sclera) visible. The background is completely black, with deep shadow. The iris should appear as a single eye, but it must be composed of the irises of two different people: 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 middle. There should be an organic and realistic transition, without a sharp line. There must be absolutely no artificial appearance, repeating patterns, or stylization. Lighting should resemble 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.
