Como mejorar la resolución en Photoshop?

I. Hola Compañero, aunque soy usuario de Gimp y no conozco apenas Photoshop, deseaba trasladarle la información sobre su consulta que vi por si pudiese serle de utilidad mientras le atiende una persona conocedora de primera mano.

Comentarle antes que tal vez la herramienta de "Escala según el contenido" pudiese ser efectiva para lo que desea hacer

También existen las herramientas independientes Upscayl y Gigapixel.

Disculpe por todas las molestias de lectura y la manera de responderle, ojalá un experto pueda atenderle pronto. Ánimo.
