Contrast

对比

The Contrast setting can be used to sharpen or soften the transition from light to dark regions. 对比度设置可以用来锐化或柔化从明亮区域到暗区域的过渡

Contrast Node defines the brightness progression of an image. Indirectly, the difference between the brightest and darkest image element will be defined. If the contrast is increased sharply, details in the lighter and shaded regions can be lost and simply be displayed as white or black. On the other hand, if the Contrast value is decreased too drastically, the image can have a muddy effect if all elements have no real discernable differences in brightness.

对比度节点定义了图像的亮度级数。间接地，将定义最亮和最暗映像元素之间的差值。如果对比度急剧增加，在打火机和阴影区域的细节可能会丢失，只是显示为白色或黑色。另一方面，如果对比度值下降太剧烈，如果所有元素在亮度上没有真正可辨别的差异，图像可能会有混浊的效果。
