Preserve the target character’s true facial identity with maximum accuracy and consistency. Maintain the exact original face shape, facial structure, natural proportions, and recognizable identity throughout the entire image or video. Keep the same skin tone values translated into monochrome while preserving realistic highlights, shadows, and natural contrast. Do not alter the person’s ethnicity, age appearance, facial anatomy, or unique characteristics.
Maintain the original hairstyle, hair length, hair volume, texture, density, and natural flow. Preserve every detail of the eyebrows, including their shape, thickness, arch, and placement. Keep the exact structure of the eyes, including eye shape, eyelids, eyelashes, gaze, and natural expression. Preserve the original nose shape, bridge, nostrils, and proportions. Maintain the authentic lips, mouth shape, lip texture, smile, and natural expression.
Keep the original jawline, cheekbones, facial contours, chin shape, and overall head proportions unchanged. Preserve any facial hair exactly as present, including beard, mustache, stubble, sideburns, or subtle texture. Maintain all accessories and personal details such as earrings, piercings, glasses, necklaces, or other facial-area accessories with the same position, size, and appearance.
The monochrome treatment should enhance the subject’s natural identity rather than stylize or modify it. Preserve realistic skin texture, pores, subtle facial imperfections, natural wrinkles or lines, and authentic human details. Avoid beautification filters, face reshaping, artificial symmetry, age changes, or any modification that makes the person look like a different individual.
Ensure the character remains instantly recognizable as the same person from the original reference image, with consistent facial identity across every frame, angle, lighting condition, and expression. The final result should feel like an authentic monochrome portrait with timeless photographic realism, preserving the person’s true appearance and emotional presence.
