一图五抠

Photoshop抠图的精典教程：一图五抠[转贴]
先贴原图
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/01.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/01.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
先用钢笔或套索工具勾出人物的主体部分，做的时候一定要注意，蚂蚁线不要太到边缘，更不能外出，否则扣出来的效果是不理想的。
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/02.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/02.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　然后进行羽化，羽化的作用是使边缘柔和，不会显得生硬。
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/03.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/03.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　羽化值根据图像的面积的大小和所选范围的大小而设定，我这里设定为1
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/04.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/04.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　然后ctrl+j自动生成 图层1
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/05.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/05.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　我将 图层1 改为“人物主体”，目的为后来的另外几种抠图备用，使大家能一目了然。
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/06.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/06.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　关闭人物主体前的眼睛，选中背景层，回到通道。大家注意看，蓝色通道的背景很干净，呈现单一的灰白。那么蓝通道就可以利用了。
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/07.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/07.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　将蓝通道拖到创建新通道图标按钮处，得到一个新的“蓝 副本”通道，如图所示：
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/08.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/08.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　ctrl+i将蓝副本通道反相，反相后，原来白的变黑，黑的变白了。但由于原来白的部分不是纯白，当然反相后就不可能是纯黑了，为了将黑度增强，就必须要进行下一步的色阶调整了。
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/09.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/09.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　ctrl+L 色阶面版跳出来了
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/10.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/10.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　将中间的小三角往右拖，圆圈内的数值由原来的1变为0.88了，蓝通道显得更黑了。
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/11.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/11.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　按住ctrl 用鼠标点击“蓝 副本”通道，蚂蚁线出现了，现在的状态为选取了白色区域，我们要的就是这个白色选区了。
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/12.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/12.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　不要取消蚂蚁线，回到背景层
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/13.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/13.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
ctrl+j自动生成“图层1”，隐藏背景层前的眼睛，效果如图所示：
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/14.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/14.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　按住ctrl，用鼠标点击红圈内的按钮，在图层1的下方出现“图层2” ，随意填充一种黄色。如图所示：
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/15.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/15.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　大家看，头发边缘效果不好，显得有些灰白，用图层菜单——修边——移去白色杂边命令可清除掉。  （ 当然也可用“正片叠底”在后面的方法里我会用到的）
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/16.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/16.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/17.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/17.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　大家看，发丝边缘现在很漂亮了
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/18.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/18.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　让人物主体层前的眼睛出现，该层为可见。大家看，现在总的效果是不是好看了呀！这种观察通道，选取可利用通道抠图到此完毕！
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/19.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/19.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　第二抠

　　教程名是“一图五抠”，第一抠完了，现在进行新的第二抠了，假如“蓝通道”同红、绿两通道一样，背景部分是花的，而不是单一的灰白怎么办呢？我现在以绿通道为例，来做个示范。
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/20.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/20.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　同样，复制绿通道为“绿 副本”，然后ctrl+i反相
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/21.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/21.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　将图放大观察，背景部分有明显的灰色块。如过用色阶来加深绿副本通道，若为了使背景够黑加深过多，会损失发丝。所以在进行色阶调整前先用画笔工具往背景上涂抹黑色。
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/22.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/22.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　现在背景比较黑了。大家注意，要涂抹整个背景。
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/23.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/23.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　ctrl+L色阶调整，如图：
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/24.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/24.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　按住ctrl，用鼠标点击“绿副本”通道，蚂蚁线出现了
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/25.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/25.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
保持蚂蚁线不取消，回到背景层
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/26.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/26.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　按ctrl+j出现“图层1”如图所示：
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/27.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/27.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　按住ctrl，用鼠标点击红圈处，在图层1的下方出现“图层2”，填充黄色，效果如图所示：
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/28.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/28.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　大家看上图，同样是发丝边缘不美观。我这次将图层1的模式设定为“正片叠底”，注意看红色椭圆里的内容。大家看效果立即好起来了。（当然大家也可象第一抠里那样将图层1移去白色杂边）
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/29.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/29.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　让“人物主体层”前的眼睛出现，该层为可见。大家看，效果也不错了。
　　第二抠到此完毕！
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/30.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/30.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　第三抠
　　接下来进行第三抠，用“抽出”抠图，复制背景层为“背景副本”
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/31.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/31.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/32.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/32.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　这是抽出面版了，注意我用红色椭圆圈住的几个地方。用边缘高光器工具在人物头发上涂抹一层绿色（涂抹其它颜色也可以），强制前景色为“黑色”，（黑色是怎样来的呢？用鼠标双击默认的白色，就会跳出拾色器，颜色应有尽有了）。设置完后点按“好”
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/33.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/33.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　回到“背景副本”层，效果如图所示：
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/34.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/34.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　让“人物主体层”前的眼睛出现。该层为可见。大家看，效果也不错！第三抠到此完毕！
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/35.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/35.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　第四抠
　　现在进行第四扣，色彩范围抠图。将前景色设定为“黑色”，注意我用红圈圈住的地方。
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/36.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/36.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/37.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/37.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
不用更改任何设置，直接点按“好”
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/38.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/38.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　蚂蚁线出现了
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/39.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/39.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　ctrl+j出现“图层1”  效果如图所示：
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/40.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/40.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　在图层1的下方新建“图层2”，填充黄色，效果如图所示：
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/41.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/41.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　将图层1移去白色杂边
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/42.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/42.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　将“人物主体层”为可见，让前面眼睛出现。显示效果如图所示：第四抠到此完毕！
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/43.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/43.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　第五抠
　　最后进行第五抠了，直接使用“正片叠底”。复制蓝通道为“蓝 副本”
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/44.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/44.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　ctrl+L色阶调整，这回三角滑块是向左方向拉的，使蓝副本通道里的黑白更为分明，注意输入色阶值的变化。
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/45.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/45.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　选中“蓝副本通道”，ctrl+a 全选，然后ctrl+c复制
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/46.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/46.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　回到图层，新建图层1，将刚才的复制粘贴到图层1，效果如图所示：
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/47.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/47.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　在图层1的下方新建“图层2”填充黄色，然后将“图层1”设定为“正片叠底”（注意红色椭圆里的内容）。效果如图所示：
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/48.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/48.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
　　让人物层前的眼睛出现，该层为可见。大家看，效果也是不错！第五抠到此完毕！到此整个教程的抠图结束了！
nmousewheel="return imgzoom(this);" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('http://www.webjx.com/upfiles/20051201/49.jpg');}" alt="" src="http://www.webjx.com/upfiles/20051201/49.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>
