<p style="text-indent: 2em;"><span style="font-family: Microsoft YaHei; font-size: 16px;">抠图是Photoshop的基本操作</span>。路径适合做边缘整齐的图像，魔棒适合做颜色单一的图像，套锁适合做边缘清晰一致能够一次完成的图像，通道适合做影调能做区分的图像。 <br /> <br /> 对于边缘复杂、块面很碎、颜色丰富、边缘清晰度不一、影调跨度大的图像，最好是用蒙版来做抠图。 <br /> <br /> 下面这张图是一位在大自然中的写生者，背景不好，需要替换。要把人物和地面抠出来，路径、魔棒、套锁、通道都不好用，还是用蒙版吧。</p> <p style="text-indent: 2em;">&nbsp;</p> <p><img src="/Public/kindeditor/attached/image/20150129/20150129154146_75696.png" alt="" /><br /> <br /> <img src="/Public/kindeditor/attached/image/20150129/20150129154343_17169.png" alt="" /><br /> <br /> <img src="/Public/kindeditor/attached/image/20150129/20150129154406_15480.png" alt="" /><br /> <br /> <img src="/Public/kindeditor/attached/image/20150129/20150129154506_58985.png" alt="" /><br /> <br /> <img src="/Public/kindeditor/attached/image/20150129/20150129154529_92726.png" alt="" /><br /> <br /> <img src="/Public/kindeditor/attached/image/20150129/20150129154557_93064.png" alt="" /><br /> <br /> <img src="/Public/kindeditor/attached/image/20150129/20150129154639_80582.png" alt="" /><br /> <img src="/Public/kindeditor/attached/image/20150129/20150129155059_60991.png" alt="" /><br /> <br /> <br /> <br /> 背景素材</p> <p><img src="/Public/kindeditor/attached/image/20150129/20150129155138_90712.png" alt="" /></p> <p style="text-indent: 2em;">&nbsp;</p> <p><span style="line-height: 2.5; font-size: 16px; font-family: Microsoft YaHei;">本教程由</span><a href="/"><span style="font-size: 16px; font-family: Microsoft YaHei; color: #003399;"><span style="color: #003399; font-size: 16px; font-family: Microsoft YaHei;">课课家网</span></span></a><span style="line-height: 2.5; font-size: 16px; font-family: Microsoft YaHei;">编辑整理，内容来自网络，非原创，如有涉权，请联系社区管理员协商处理。</span></p>
