Every place, either interior or exterior, is distinct. Its distinctiveness doesn't lie only on decoration, lighting and architecture, but also on it's owener's personality. By photographing this place, you should try to capture this style that s/he wants to transfuse. You don't want these photos to be just a simple image of an interior/exterior place. What you really want is that when someone sees these photos, he is able to guess the character of both the owner and the decorator. In this way you get customer's attention and he will have the curiosity to visit the place!
