We come up against problems representing light because it is so inherent to our sense of the volume and character of the space.
Walls are an essential element in the design of interior spaces.
They are the broad brush strokes of the interior design composition and are central to interior space planning. Functionally, walls form volumes, offer privacy or security, and provide surfaces on which objects can be stored or displayed. Lighting fixtures are designed to produce downward, upward, or multidirectional light output with either concentrated or diffuse distribution. As designers change the patterns of light, shade, and color in a room, the inhabitants, in turn, receive altered subjective impressions. Of course you will want to light up some samples as part of this analysis, but first you must narrow your choices.
