A photograph is usually looked at—seldom looked into. — Ansel Adams
The camera views perspective differently than the human eye. When photographing an interior space, be open to moving furniture or other items in the scene further or closer to the camera to compliment what is seen through the viewfinder, and not necessarily what you are seeing in real life.
When choosing a subject to photograph, sticking to clean and simple lines will have a great deal of impact.
Studio flash is integral to balancing shadows inside the room and matching the overall level of light to the level coming in through the windows, resulting in properly exposed exteriors fused with properly exposed interiors.
