Correction of photos for portfolio

We need to prepare photos for the portfolio. There are 60 pictures. The quality of the photos is not very good, they were not made in the studio. Therefore, you need to first choose the best 12-15 photos from what is (different in style, genres), i.e., the best photos. "Portfolio" is a set of professional art photographs that maximize the advantages of the appearance of the model and present it in the most favorable light. And then make correction of the photo (format, retouch, tweak, etc.) so that the photos were similar to studio ones. The size of the photos will be from 1200 px in width, so the retouch of the photos should be of appropriate quality, and examples of photo correction work should be at least as wide as this size.
