Create a Diagonal Neon Split Reel Cover From One Portrait

A strong Reel cover needs a clear subject, immediate color contrast and space that stays readable beneath interface overlays. This prompt turns one adult man portrait into a person-centered neon-green and black cover without generating fake platform text or logos.

Rights and accuracy note: Use a rights-cleared, licensed, public-domain or user-owned source photo. The featured sample is an original fictional portrait example and does not depict a real public figure or documentary event. Add real names and copy outside the generated image, and label a materially AI-edited result when appropriate.

AI Photo Editing Prompt

PromptUse the uploaded rights-cleared portrait of the same adult man as the exact identity reference. Preserve his face, facial structure, hairstyle, expression, skin texture, body proportions, clothing and pose. Replace the background with a clean dark studio and create one unmistakable hard diagonal boundary running from the upper-left toward the lower-right: deep matte black on one side and a vivid neon-green illuminated field on the other. Let the neon green spill subtly onto the shoulder while keeping the face naturally lit with soft neutral light. Use a realistic 35mm portrait perspective, sharp eyes, restrained matte texture and strong thumbnail contrast. Leave the entire lower third dark, clean and empty for manually added Instagram Reel copy. Do not render words, letters, numbers, logos, watermarks, app interfaces or event claims. Create a realistic vertical 9:16 photo edit.
