曲线是Photoshop中最常用到的调整工具,理解了曲线就能触类旁通很多其他色彩调整命令。 按CTRL M键打开曲线对话框,曲线是在一个二维坐标系中,横轴代表输入色调,纵轴代表输出色调,从白到灰到黑依次代表高光、中间调和暗调。

按CTRL M键打开曲线对话框,曲线是在一个二维坐标系中,横轴代表输入色调,纵轴代表输出色调,从白到灰到黑依次代表高光、中间调和暗调。

我们先打开一张图片。如果想对图像中草棚个部分进行调节,打开曲线,然后按住CTRL键在图像单击。曲线上就会出现一个点,调整这个点就可以调节局部的图像。我们将要调整这张图的最鲜艳颜色和最暗颜色两个部分。



然后做个调整,效果如下。



设置黑白场

如果照片色彩灰暗低沉,最暗的地方不够暗,最亮的地方不够亮,整体色调呈灰暗,如下图。



打开曲线对话框,点击“设置黑场”,找到画面中的最暗点,用黑色吸管吸取,画面的暗部加强,如下图。
选择最暗点的方法:可以参照界面右上方的的信息窗口,其中CMYK信息的K值表示颜色的明暗,K值越大,所选点颜色最暗;K值越小,所选点颜色最亮。



然后再做白场调整,点击“设置白场”,找到画面中的最亮点,用白色吸管吸取。这是画面会产生明显的变化,整体色调就明快了。



设置灰度点

合理设置灰度点能够调整图像的色调,特别是一些严重偏色图像,如下图。



打开偏色图像后,调出曲线对话框,选择中间的“设置灰场”,用灰色吸管吸取画面上无色彩点(如最深色的黑色,纯黑的瞳孔、眼白或者画面上有灰色的水泥地)。

先做个试验,吸取图像上最亮的地方。(注意:只是做试验,不要点击确定关闭曲线对话框。)



本次图像调色则应该吸取最暗的地方。



OK. 这样色彩就比较舒服了。
