Améliorer une photo en HD / 4K

Ultra-Premium 16K Professional Remaster & Enhancement. Preserve the image
exactly as provided while dramatically improving quality, realism, sharpness, and
clarity. Enhance only existing visible details — do not invent, generate, reconstruct, or
add facial features, hair, beard strands, pores, wrinkles, clothing details, or textures
not present in the source. Maintain the exact face, hairstyle, beard density,
expression, skin tone, facial proportions, lighting, colors, clothing, and composition.
Improve only through faithful super-resolution, natural sharpening, artifact removal,
noise reduction, texture refinement, and realistic detail recovery. Preserve the original
background exactly — do not replace, redesign, extend, reimagine, or add elements.
Apply subtle improvements to clarity, textures, gradients, edges, lighting fidelity, and
resolution while keeping the background visually identical. Professional camera
realism, authentic optics, realistic dynamic range, premium color science, clean
highlights, rich shadows, natural micro-contrast, crystal-clear focus, luxury
commercial photography, medium-format fidelity, magazine-cover finish,
production-ready 16K master.
