Use your camera monitor to figure out how to adjust and turn furniture and items to make them look good on camera. This could be challenging if you are doing multiple camera angles, with chairs and decor on foreground tables overpowering the focus.
Place items so that they will look good on all cameras, not just the main one.
Non-reflective elements and flat paints that do not reflect very much light are recommended for sets. Light is difficult to work with because it can bounce directly into the camera lens.
Sometimes you do want to use a little reflection or sparkle of light in your shot to add a sense of movement or energy in the background. It is good to have some options to change things out if needed if a client or director doesn’t like something.
