教程作者：佚名



利用图层混合模式和通道抠图这是原标志图：http://pic1.16xx8.com/article/UploadPic/2007/10/27/2007102765644846.gifhttp://pic1.16xx8.com/article/UploadPic/2007/10/27/2007102765644884.pnghttp://pic1.16xx8.com/article/UploadPic/2007/10/27/2007102765644576.gif 1.png (3.87 KB)2007-6-26 10:21 现在要将标志中黄色的背景去除在这里介绍一种方法，先利用图层混合模式和色阶调整再通过通道创建选区，之后填充颜色来完成首先在标志图层下方建立一个色彩填充层填充的颜色选择标志色彩最浓的区域（如下图）http://pic1.16xx8.com/article/UploadPic/2007/10/27/2007102765644846.gifhttp://pic1.16xx8.com/article/UploadPic/2007/10/27/2007102765644689.pnghttp://pic1.16xx8.com/article/UploadPic/2007/10/27/2007102765644576.gif 2.png (41.79 KB)2007-6-26 10:21然后将标志层的混合方式改为“变暗（Darken）”http://pic1.16xx8.com/article/UploadPic/2007/10/27/2007102765644846.gifhttp://pic1.16xx8.com/article/UploadPic/2007/10/27/2007102765644193.pnghttp://pic1.16xx8.com/article/UploadPic/2007/10/27/2007102765644576.gif 3.png (16.01 KB)2007-6-26 10:21之后背景将变为深色，用信息面板（Info）察看背景颜色，还不是纯黑色（纯黑的RGB值均为0）http://pic1.16xx8.com/article/UploadPic/2007/10/27/2007102765644846.gifhttp://pic1.16xx8.com/article/UploadPic/2007/10/27/2007102765645957.pnghttp://pic1.16xx8.com/article/UploadPic/2007/10/27/2007102765644576.gif 4.png (22.14 KB)2007-6-26 10:21然后建立一个色阶（Level）调整层，使用右下角三个吸管的第一个，在背景上点一下这代表将原先的背景色强行改变为纯黑http://pic1.16xx8.com/article/UploadPic/2007/10/27/2007102765644846.gifhttp://pic1.16xx8.com/article/UploadPic/2007/10/27/2007102765645300.pnghttp://pic1.16xx8.com/article/UploadPic/2007/10/27/2007102765644576.gif 5.png (24.86 KB)2007-6-26 10:21 之后再用信息面板看一下，背景已经是纯黑的了http://pic1.16xx8.com/article/UploadPic/2007/10/27/2007102765644846.gifhttp://pic1.16xx8.com/article/UploadPic/2007/10/27/2007102765645252.pnghttp://pic1.16xx8.com/article/UploadPic/2007/10/27/2007102765644576.gif 6.png (23.29 KB)2007-6-26 10:21 然后将蓝色通道作为选区载入（按住Ctrl点击蓝色通道即可）http://pic1.16xx8.com/article/UploadPic/2007/10/27/2007102765644846.gifhttp://pic1.16xx8.com/article/UploadPic/2007/10/27/2007102765645857.pnghttp://pic1.16xx8.com/article/UploadPic/2007/10/27/2007102765644576.gif 7.png (19.19 KB)2007-6-26 10:21在利用这个选区建立一个色彩填充层就完成了http://pic1.16xx8.com/article/UploadPic/2007/10/27/2007102765644846.gifhttp://pic1.16xx8.com/article/UploadPic/2007/10/27/2007102765645162.pnghttp://pic1.16xx8.com/article/UploadPic/2007/10/27/2007102765644576.gif 8.png (19.79 KB)2007-6-26 10:21最终效果 http://pic1.16xx8.com/article/UploadPic/2007/10/27/2007102765644846.gifhttp://pic1.16xx8.com/article/UploadPic/2007/10/27/2007102765645729.pnghttp://pic1.16xx8.com/article/UploadPic/2007/10/27/2007102765644576.gif 9.png (3.56 KB)2007-6-26 10:21http://bb.a.5d6d.com/userdirs/8/7/chacha163/attachments/day_070725/20070725_a7c1e26e4af909b3bf53b9VGezdsMndj.gifhttp://www.16xx8.com/1diy/imges/wxapp_2wm.jpg
