轉貼,在這裡邊緣也是指眼睛看到的線條,這一篇主要是給上色的畫家使用,但是漫畫家也可照這參考線條,本篇非常注重光影
Ewell:
In general, edges are:
(基本上, 邊緣是...)
Harder in the light, softer in the shadow
(在光下面較硬,在影子下較軟)
Harder in bright light, softer in dim light
(在強光下較硬,在軟光下較軟)
Harder in focused light, softer in diffused light
(在專注的光下較硬,在散光下較軟)
Harder in the foreground, softer in the background
(在畫面前方較硬,在背景裡較軟)
Harder on smooth forms, softer on textured forms
(在光滑的表面上較硬,在有紋理的表面上較軟)
Harder on hard forms, softer on soft forms (Duh, but really)
(在硬的物體上較硬,在軟的物體上較軟) -那當然囉!...拜託...
Harder on flat forms, softer on rounded forms
(在平面的物體上較硬,在圓體上較軟)
Harder on thin forms, softer on thick forms
(在薄的物體上較硬,在厚的物體上較軟)
Harder on still forms, softer on forms in motion
(在靜體上較硬,在動體上較軟)
Harder at the center of interest, softer as you move away
(在視覺焦點較硬,越遠越軟)
