Prompt

Apply a Sepia Matrix effect, remapping the photograph into warm brown shadows, coppery midtones, and pale cream highlights. Create a unified historic photographic palette with smooth tonal transitions and intact surface detail. Avoid added scratches, vignettes, paper borders, or artificial grain. Keep the original subject and composition.
