Let's pretend for a moment that it's not at all creepy for three sisters (even if one's only half-related) to pose seductively in lingerie together and take a look at the composition here. If you think there's nothing deceptive going on, let me clarify how a professional photographer goes about removing half of a person's mass from a picture. First, he sets up at least fifty yards away and racks until he's just barely in focus. Then he reassesses, has his assistant bring over a bucket of scotch and fires the rest of the crew because their salaries are now needed for a photoshop editor. Don't believe me?
