Some of the best portraits I've seen have had "imperfections". Wrinkled skin, a crooked smile, droopy eyes, etc. They help tell the story of the individual and add to his/her character. Of course, I'm speaking from the point of view of a photograher. If it was me in the picture, I'd want a lot adjustments
. I can see that this would be useful for photographers taking shots of high school seniors or brides, not to mention commercial photography where you are trying to sell a product.
