Lab模式打造特殊色调在外景照片中,使用Lab模式还可以调整出各种特殊的色调,下面我们介绍几种调整方法。在Photoshop中打开一幅足球宝贝的照片,如图3-1,执行【图像/模式/Lab颜色】菜单命令,将其转换为Lab颜色模式,在弹出的对话框中选择"拼合"。其通道效果如图3-2。按下Ctrl+J快捷键,复制图层。1选择a通道,全选(Ctrl+A),拷贝(Ctrl+C)。然后选择b通道,粘贴(Ctrl+V)。效果如图3-3所示。这是因为,观察图3-2,原图中a通道的上半部分偏暗,所以在图像中显示为绿色;当把a通道的内容拷贝到b通道之后,b通道的上半部分也偏暗,呈现为蓝色。
Lab mode is one of the three color modes of Photoshop. Those who often use Photoshop are familiar with the color modes of RGB and CMYK. However, few people are familiar with the color mode of Lab, which is also extensively applied to the image processing. Under the Lab mode, it is simple and rapid to adjust the colors. This article will introduce what it the Lab mode and its application in Photoshop.
