Client: “We don’t like this girl’s smile on the brochure cover. Can you photoshop another mouth onto her face from one of the other photos?”
Me: “Unfortunately, none of the other photos of her smiling are from the same angle.”
Client: “Well, then photoshop her whole head out and use a head from the other photo where she is smiling.”
Me: “Can’t do it. The heads aren’t from the same angle as the body. It won’t look right.”
Client: “Sure it will! People photoshop heads and body parts all the time.”
