Tried a simple restoration prompt on an old photo and the result came out surprisingly strong.
The main thing is keeping it natural.
Not over-editing it.
Not changing the people.
Sharing the prompt here if anyone wants to test it:
"Restore this old photo into professional portrait of DLSR - quality colour and detail, using an advanced upscaling algorithm comparable to the results from canon EOS R6 II. Ensure the restored the image looks natural, retains exact facial features, has great clarity"
Good one to try on vintage family photos or historical images.
