What is the filter used on this image ?
Hello to all you experts,
I am repeatedly seeing a new type of filter being used to transform a mediocre quality photo into a smooth picture with sharp definition. I assume it's done with Photoshop but it could be an app.
The picture remains sharp but it is smooth at the same time. Also, the background has been blurred, which I noticed is always the case with this type of retouching. So maybe it's part of the automatic treatment, or something that the graphist does separately. Thanks in advance for your help !
