Well, directing criticism also to the owner of the image because he expressed admiration goes against logic, I personally do not want to discuss much about this subject. The goal of restoring images is to reach a picture as if it (was taken yesterday), and I think that is the (golden goal), and for this reason Adobe Photoshop and others are keen on Developing its software and techniques in removing blemishes and frills, increasing image sharpness and accuracy, and correcting shadows and colors. Without exaggeration, I learn something new every day by following lessons here and there. Using Adobe, you can sharpen the edges to the maximum degree possible, and then smooth these edges using other tools. Why we are Against development and raising efficiency..Personally, I do not hesitate to inquire how anything was done because every day we learn something new.I used topaz gigapixel just to increase photo size without loosing quality, Use the smudge tool on 2 separate layers - 1 set to Darken and 1 set to Lighten, Fix the details like blotchy faces, reflections, missing chunks and blurred details using Frequency Separation, I will attach AI enhanced photo to compare with previous restoration .
