Detaillierter Prompt zur Restaurierung alter Fotos mit GPT Image 1.5

Ein hochdetaillierter, strukturierter JSON-Prompt, der für die Porträtwiederherstellung alter Fotos entwickelt wurde und die Ergebnisse zwischen Nano Banana Pro und GPT Image 1.5 vergleicht. Der Prompt konzentriert sich auf die Wahrung der Identitätstreue, die Verbesserung spezifischer Details wie Augen und Hauttextur sowie die Steuerung von Beleuchtung und Bildqualität für ein ultrarealistisches, filmisches Ergebnis.
