Faithful old-photo restoration

Restore the supplied historical photograph conservatively.

Repair visible [DAMAGE: SCRATCHES, CREASES, DUST, TEARS OR FADING]. Recover contrast and tonal range from surviving image information. Reconstruct tiny missing areas from immediate neighbouring evidence, preserve natural film grain and keep the original framing, people, facial identity, age, clothing, objects, architecture and period details unchanged.

[COLOUR INSTRUCTION: KEEP BLACK AND WHITE / RESTORE ORIGINAL COLOUR / CAREFULLY COLOURISE]

If colourising, use historically plausible, restrained colours and do not imply certainty where the original provides none. Do not beautify faces, sharpen into artificial plastic detail, replace the sky, modernise the scene, add objects or remove historically meaningful marks. Output one restored master at the source aspect ratio and a second version retaining the untouched border when present.
