Hi all,
Lot of thanks for your advice.
On GIMP
To restore faded photos tinted with yellowish color, most
time I run;
- Colors → Auto → White Balance
OR - Colors → Levels → Auto Input Level
It is very simple only with one click. But they are NOT 100% workable in all cases therefore I begin looking for other solutions.
The faded photo was first scanned on Samsung Galaxy S22 Ultra mobile phone with macro lens at 1.0. Then I cropped the positive digital photo on GIMP and ran;
Colors → Auto → White Balance
No further post-editing was made.
The wall is in white color according to my recollection. I captured the photo.
Regards
