It doesn't really matter whether it's domestic, retail or corporate when it comes to interiors, it's more than just the furniture.
The structure and light are one of the first things to look at when setting up to capture an interior.
What are the main building blocks that create the space? What are the types of lighting and in what directions is the area illuminated?
The space is create by form and made for function. So how and what is it used for? How would you move through and around the space?
These are some of the thought processes that the architect, interior architect and/or interior designer has put in to the space. It must also be the thoughts of the photographer.
