最后的效果图

onmousewheel="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(this.src);}" alt="" src="/upimg/allimg/070928/1434020.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" />

原图

onmousewheel="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(this.src);}" alt="" src="/upimg/allimg/070928/1434021.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" />

onmousewheel="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(this.src);}" alt="" src="/upimg/allimg/070928/1434022.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" />

执行%26ldquo;滤镜>杂色>减少杂色%26rdquo;命令，如下图所示设置。

onmousewheel="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(this.src);}" alt="" src="/upimg/allimg/070928/1434023.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" />

　　单击%26ldquo;确定%26rdquo;按钮。杂点太多是上色的一个大忌。多谢Photoshop CS2提供%26ldquo;减少杂色%26rdquo;这个超酷的命令，能让图像迅速的消除杂色并且保持图像的清晰度。个人认为这是CS2新功能中最优秀的功能之一。（如果不用CS2的人就想着用其他方法去消除杂色了，反正我有了这个功能是不做其他的选择了，呵呵。）

onmousewheel="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(this.src);}" alt="" src="/upimg/allimg/070928/1434024.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" />

　　执行%26ldquo;图层>新建调整图层>色阶%26rdquo;命令，设置如下图所示：

onmousewheel="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(this.src);}" alt="" src="/upimg/allimg/070928/1434025.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" />

　　单击%26ldquo;确定%26rdquo;按钮，得到结果如下图所示：

onmousewheel="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(this.src);}" alt="" src="/upimg/allimg/070928/1434026.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" />

　　这个部分的重点在于有丰富的层次，颜色尽量过渡比较自然，不要有太多杂色，上色前如果是RGB模式，尽量将其恢复成灰度色调。

　　执行Ctrl＋A（全选）命令，再执行Ctrl＋Shift＋C（合并拷贝），在执行Ctrl＋V（粘贴）。这是我个人的习惯，不习惯破坏原图像，所以就多复制一个图层。

图层，在图层上先为军装上色，尽量着一些同类色进行绘制，这样可以使得上色看起来颜色比较丰富。

onmousewheel="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(this.src);}" alt="" src="/upimg/allimg/070928/1434027.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" />

　　将改图层的图层混合模式改为%26ldquo;颜色%26rdquo;。

onmousewheel="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(this.src);}" alt="" src="/upimg/allimg/070928/1434028.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" />

　　 实这一步并不是先画好了，再改成%26ldquo;颜色%26rdquo;模式的，而是直接在%26ldquo;颜色%26rdquo;模式绘制的。这样能够比较直接的看到结果。

　　为了上色更加的容易修改，再新建图层，对背景上色。

onmousewheel="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(this.src);}" alt="" src="/upimg/allimg/070928/1434029.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" />

　　改为颜色模式后，如下：

onmousewheel="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(this.src);}" alt="" src="/upimg/allimg/070928/14340210.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" />

同样的新建图层，为脸部上色。

onmousewheel="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(this.src);}" alt="" src="/upimg/allimg/070928/14340211.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" />

　　改为颜色模式后，这就是最后上色的结果，看以下最后效果图：

onmousewheel="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(this.src);}" alt="" src="/upimg/allimg/070928/1434020.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" />

　　后记：

　　上色是一个复杂的过程，我继续补充以下几点，有几个问题是在上色中需要注意到的：

　　1、特别是大面积的颜色，一定要做点变化，不然就会看起来比较呆板。

　　2、上色时务须颜色都上得边缘线很整齐。稍微的过界可以增加颜色的丰富层次。

　　3、上色时尽量降低画笔的不透明度，多画几次，这样的上色层次会比较丰富。

　　4、注意在调整上色图像时，请参考我的色阶参数设置。

　　5、上色时不知如何取样颜色时，可以找一张自己喜欢的颜色的照片用吸管取色。
