Depth Preception

This is a picture that I found using google image search under the term of "illusion of space". They use mirrors on the 3 ceiling windows that creates a illusion that gives out a sense of extra space. They are actually just mirrors' reflection from the living room ceiling. The room that you see on the right hand side is just a coat closet. The mirrors' reflection also extends the linear perspective from the horizon line. It makes the ceiling seems to be continued to the next room, but actually 2/3 of space you saw in that room is just solid concrete. The TV and the displays is using visual element of familiar size to compare with the everyday objects. It gives you a sense of scale to compare with the environment. The small and narrow display cabinet gives out a feeling of huge extra space if you compare to the huge unused wall on the left of the cabinet. Discrimination of perception plays a key roll in this photo, which it's widely use in creating of space in this case.
