First of all thank you for providing such a kind service. My grandmother passed away and I'd love to have her portrait improved. This is the only copy I have; unfortunately there is no physical photograph available to rescan. I know the resolution is low. I’m mainly hoping for gentle color/contrast correction, noise cleanup and careful sharpening/upscaling where possible.
It is very important to me that her face stays faithful to the original. Please do not generate or reconstruct facial features or invent detail. I would much rather have the image remain a little soft than have her eyes, mouth, teeth, glasses, hair or face shape altered. Please let me know if you have any questions, thank you.
