They are so beautiful why not take the spots off the girl in the middle?
Thank you, they are beautiful! And personally, I think they are beautiful just the way they are!
They are teenage girls posing at their prom, not models. Just because we can, doesn't always mean we should. If these were paid-for senior portraits, I could cross that bridge and ask them if they would like me to do some additional touch up work, but this is just a quick candid between 3 best friends.
At this age, everything is a self confidence issue, and by removing too much in the way of "spots", we emphasize something that is perceived as being "bad" or wrong. Remember, this is a candid not a portrait.
Acne is a different issue however, and I have no problem getting rid of blemishes.
