Get a better result

What you will get

A sharper, high-resolution version of a small old portrait, ready to print at the size you named, with skin, hair and fabric detail recovered while expression, clothing and composition stay the same.

Why it works

Upscaling can invent a new face, so the prompt says plainly not to. It asks for natural detail in skin, hair and fabric and protects the expression, clothing and composition. The print size blank tells the model how sharp it needs to be.

Common mistake

The face turns into a different person, a real risk at low resolution.

Fix: Repeat “do not invent a different face, keep the original expression”, and compare eyes, nose and mouth side by side with the original before printing.

Also watch for

The result looks plastic, with all texture smoothed away. Ask for “keep natural skin texture and the grain of the old photograph”. Over-clean pictures look fake.
You start from a phone screenshot and the detail is poor. Follow the tip and use the highest-resolution scan you can find. If there is none, photograph the print flat in daylight.

Try a variation: repair afterwards

For a damaged print, upscale first, then run a second pass with “repair scratches and fold lines, keep it black and white”. Each step then has one clear job.

Keep my exact face from the original photo: same eyes, nose, smile, skin tone and age. Change only the style.
