Create an ultra-realistic professional studio graduation portrait of an adult man standing confidently behind a polished black desk against a seamless dark charcoal-gray studio background. Position him centrally, leaning slightly forward with both hands resting firmly on the desk, shoulders squared, facing directly toward the camera with a calm, serious, confident expression. Dress him in a formal black academic doctoral/graduation gown with striking royal-blue velvet panels and elegant metallic-gold piping. Add multiple royal-blue velvet sleeve bars outlined with gold trim on both arms. Underneath the gown, dress him in a crisp white formal shirt with a sophisticated red, navy-blue, and silver diagonal-striped necktie. Complete the academic attire with a traditional black velvet Tudor-style academic bonnet, featuring a soft rounded crown, structured brim, and a long royal-blue tassel hanging naturally to one side. Place several neatly stacked academic books on the left side of the desk and one clean white academic book on the right, creating a balanced scholarly composition without distracting from the subject. Use a dark monochromatic charcoal studio backdrop with subtle tonal gradients and no visible distractions. Illuminate the subject using professional softbox lighting from the front and slightly above, producing clear facial details, realistic skin texture, controlled highlights, and gentle shadows while keeping the background darker. Capture the portrait at approximately waist-up level using an 85mm portrait-lens look, straight-on camera angle, shallow depth of field, crisp focus on the face and academic attire, realistic fabric textures, natural proportions, refined color grading, high dynamic range, premium university graduation photography, photorealistic, highly detailed, 8K quality. Composition: centered symmetrical portrait, black desk across the foreground, generous negative space above the academic cap, vertical 3:4 aspect ratio. Avoid: distorted hands, extra fingers, incorrect academic-gown details, warped books, excessive skin smoothing, cartoon appearance, exaggerated facial features, jewelry, text, logos, watermarks, or distracting background elements.
