การบูรณะภาพถ่ายเก่าสู่คุณภาพ DSLR สมัยใหม่

Restore the provided old portrait photo to a modern, high-clarity professional DSLR photograph. Preserve exact facial features, likeness, expressions, and original identity from the reference photo. Enhance color fidelity, skin textures, hair definition, and eye clarity with natural lighting and depth of field reminiscent of a Canon EOS R6 II portrait shot. Remove grain, scratches, blur, and discoloration while keeping the final result completely natural and un-airbrushed.
