Hi Jim,

Photographers did use good lighting technics, and makeup, and portrait lenses to eliminate facial lines and skin inperfections.

Today's photographers use the sharpest lenses for portrait which shows the smallest skin problems, than use PS bluring tool, to eliminate them. Make no sense! Use portrait lens, and don't set the highest sharpnes on a camera during the photoshoot.

There was photography before PS! But today, looks like no one can do picture without it.

I believe the retouch is OK until it is not create a different person, from the subject. This women is a 40+ but after the retouch she became a teenager.
I believe, any kind of retouch should be only cover temporari skin inperfections, like cuts or pimples, or bug bites, etc. Everything else which is permanent on the subject face should be remain on a photo.
