noun · C1
A kind of carving in stone or wood in which the shapes stand well out from the flat surface behind them — at least half of their full depth — so they look almost separate from it.

可以想成站在一面石雕牆的側邊看。有些圖案只是淺淺浮起來，有些卻凸得很遠，遠到手指幾乎伸得到後面去。凸得多的那一種就是 high relief。因為形狀離開了平面，光一打上去，後面就落下很深的影子。這個畫面裡最關鍵的一句是：它不肯待在背景裡。你看那面牆，就一定會看到它。Two branches
借來形容「特別明顯」的固定說法
從雕刻那個畫面借過來：凸出平面，所以跑進眼睛裡。這是用法上的比喻，不是說這個片語從別的字演變而來。

If one thing throws another into high relief, it makes that other thing very easy to see or notice, usually because the difference between them is so big.
