I tried uploading an old photo, but during the repair process, I lost some things, resulting in a result that was not what I wanted. This algorithm still needs to be updated
In both of your example images with young men, it's added stubble where there was none. It's also removed moles from Einstein's face.
This doesn't seem to be very accurate!
I would like to have some control over the process. I uploaded a picture of my father taken around 1958- 1960. It's blurry and he is wearing a shirt and tie and must have been around 7-9 years old . The restored image shows him as a middle aged man, wrinkles included. Would be nice to specify a couple of aspects
Does it include any kind of prompt you can modify? I've used palette.fm in the past (a photo colonization tool) and it gives you different options to modify how the color looks for the end result as well as manually editing the prompt it creates based on image recognition so you can adjust the final output.
sarah mitchell's feedback more than enough
To be honest: not a fan. It creates a completely new image based on a photo, rather than fix it. The Einstein photo shows particularity well how pretty obvious facial features just get removed. The results look nice, but they are definitely not a restoration, but a generated image.
