No division between wall and ceiling

A treatment of the wall-to-ceiling junction. Here, there are no cornices, no cove moldings, no grooves, but rather a continuous transition with a radius of about three centimeters. The wall and ceiling are made of the same material, the same color, and applied in a single process. Therefore, when looking up, one cannot find where the upper edge of the room is, and the boundaries of the space dissolve into the gradient of light. Because it is diffused light, the changes in light and shadow on that arc are continuous and soft, further reinforcing the feeling of no boundaries. In one corner of the picture, a common approach is shown for comparison: a clear cove line separates the wall and ceiling, immediately defining the height of the room. Avoid: making the two versions similar, adding cornices and cove moldings, using different colors for the wall and ceiling, making the arc too large, giving it a dome-like feel.

一段牆與天花的交接處理。這裡沒有線腳、沒有陰角條、沒有溝縫,而是以一道半徑約三公分的圓弧連續過渡,牆與天花是同一種材料、同一個顏色、同一次施作。因此往上看時找不到房間的上緣在哪裡,空間的邊界溶解在光的漸層裡。因為是漫射光,那道圓弧上的明暗變化是連續而柔和的,更強化了沒有界線的感覺。畫面一角以一般做法作對照:一道明確的陰角線把牆與天花切開,房間的高度立刻被界定出來。避免:讓兩者相似、加入線腳與陰角條、讓牆與天花使用不同顏色、把圓弧做得過大變成穹頂感。
