SMALL PHOTOS - ON A TABLE OR SHELVES, BUT NOT A WALL. Many miniature photos or other images decorating the wall are perceived as visual noise. But on the table or shelves they look appropriate. It is advisable to arrange such decor in similar or identical frames. INTERIOR AND DECOR - FOR RESIDENTS OF THE HOUSE, NOT FOR THE DECORATOR. If home improvement is done by professionals, it is important that at the end of the work the owners do not have the feeling that they are in someone else's home. Therefore, the owner’s desires are a priority, and the decorator’s task is to find an acceptable and aesthetic form for them. BALANCE OF LIGHT AND SHADOW.

For example, for the convenience of staying in residential lighting, a multi-level layout of lighting fixtures is mandatory. Lighting also affects the perception of colors.
