When you start out, try to think like a professional photographer. A pro wouldn't come into your home unprepared and spend a few quick minutes snapping shots — so you shouldn't either. Before you pick up the camera, think about the story you want to tell with your images. Where are the critical spaces, and how do you want to express them? What pieces are stifling the scene? Map out your plan of attack, even breaking it up into stages if it feels overwhelming. Follow the advice below, practice and try not to rush the process.
