I always like to have a money shot as one of my finals. Up early our ar dawn because of the building orientation. Pre sunrise is when all of the magic happens. Some things are out of my control like the cars parking in front of the building. It is always difficult to not get people in your shots after the hotel is open. The best way to achieve that is shoot at pre sunrise and use the outside light as a contrasting color.I always start with a long shot and work my way in closer.
It is either early morning or at dusk when all of the magic happens.
