horizon line

基本解釋

The Earth's curvature is visible along the horizon line, or limb, that extends across the image from center left to lower right.
沿著地平線或者側(cè)面，地球的曲線從圖片的左側(cè)中部延伸到右下方。
When shooting a scene that includes not just the sky but also other elements like a cityscape, keeping the horizon line straight is particularly important.
如果我們拍攝的畫面中除了天空，還有一些其它的元素（如城市景觀），使地平線保持水平非常重要。
We can look at this image and easily visualize the horizon line and the buildings stretching past the left and right edges, almost as if we’re looking through a window.
看著這幅畫作，我們眼前很容易便顯現(xiàn)出：地平線與建筑延伸到了左右兩邊以外，就好像是透過一扇窗在看似的。

Implied "horizon line" lends stability and repose to composition.

It rose little by little on the horizon line as we power walked our way to it, passed the Kazakhs and Tajiks selling trinkets and wrestling with each other in the square.
