Michal Venera: You really want to have a wide selection of shots, so take more than you normally would. Experiment with all sorts of angles and frames so there are a lot to choose from. When you're shooting an interior, deciding whether or not to include people or animals is usually the decision of the client. If you do opt to include people in your shots, it always looks better and is easier if you're not shooting them straight on. If you get a side or profile view, it's a bit better, and doesn't draw attention to the person. You want the focus to be on the interiors. If you don't want to include people, or if the client doesn't want you to, it's always nice to create the illusion that the space is lived in — even if it isn't. A half glass of water or something similar can help you do that without adding people.
