Posing is an art; it’s not something you can just look up in a textbook. Every couple is different & it is imperative that you get a good feel for what the couple is comfortable with before you embarrass them (and yourself!).
Getting great photos (often times) relies on composition… and posing is your own way of getting them to do the lovely things that make a great photo. Some people think that “posing” means you aren’t capturing candid moments and that is completely NOT true.
