The professional provides guidance as to flattering wardrobe, advises on props and accessories, and harmonizes color to suit the desired mood. He (or she) doesn’t plop his clients in front of his lens and tells them to “do their thing” and smile. Rather he guides them into a pleasing composition. He’s always scanning the frame for pleasing and purposeful hand placement, looking for a collar that’s popped up, an errant strand of hair that’s distracting, and ensures the lady’s necklace is hanging properly. In short… controlling the details.
