(10-2):使用字符调板
1012以上是在文字工具的公共栏中出现的选项。在点击了字符调板按钮后即会出现字符调板【窗口_字符】，如下图。在其中可以对文字设定更多的选项。在实际使用中也很少直接在公共栏中更改选项，大多数都是通过字符调板完成对文字的调整的。其中的字体、字体形式、字号、颜色、抗锯齿选项就不重复介绍了。注意其中的为亚洲文本选项，需要在Photoshop首选项〖CTRL_K〗的常规选项中开启“显示亚洲文本选项”才会出现。1013拼写检查选项是针对不同的语言设置连字和拼写规则，如下右图显示了英国英语和美国英语对同样文字的不同连字方式。注意，末尾连字只有在框式文本输入时才有效。因为框式文本是自动换行的。通过手动换行的文字是不会有连字效果的。有关框式文本的输入方法在本节后面部分介绍。连字和拼写规则对于中文是没有意义的。因为汉字为单体结构，即一个汉字字符已携带完整含义，而字母系语言需要多个字符组合才能携带完整含义。也正是因为汉字携带的信息巨大，因此现在电脑的计算能力还不足以完美处理中文化的信息结构。-1014行间距控制文字行之间的距离，若设为自动，间距将会跟随字号的改变而改变，若为固定的数值时则不会。因此如果手动指定了行间距，在更改字号后一般也要再次指定行间距。如果间距设置过小就可能造成行与行的重叠。如下左图是自动行距与手动指定为12像素行距的比较。如果有重叠发生，下一行文字将会遮盖上一行。1015竖向缩放相当于将字体变高或变矮，横向缩放相当于变胖和变瘦，数值小于100%为缩小，大于100%为放大。如下右图中3个字分别为标准、竖向50%、横向50%的效果。-1016在字符调板中有比例间距和字符间距，它们的作用都是更改字符与字符之间的距离，但在原理和效果上却不相同。我们可以动手来理解它们的区别，新建一个足够大的图像，打上simple这几个字母，字体为黑体，大小为72像素。如下图左端所示，我们看到整个文字的宽度是由字符本身的字宽与字符之间的距离构成的。这两者都是在制作字体的时候就定义好的。有的字符本身较窄，但其左右的字距也较大，这样做是为了保证每个字符占用的宽度一致。否则，较窄的字符就只能占用较小的宽度。但这种设计却也造成了字符之间疏密不同。如下图中的mp之间与pl之间的疏密就不同。这种情况一般出现在使用中文字库输入字母的时候，Windows系统自带的黑体、宋体、楷体字体都存在这种现象。因此输入英文时应避免使用这些字体。字宽与字距间的比例将随着字号的大小相应改变，也就是说，对于同一个字体来说，字号越大，字符之间的距离也越大。反而反之。那么，字符间距选项的作用相当于对所有字距增加或减少一个相同的数量。可手动输入数值。如下图中将字符间距减去100，所有的字符间距都减去100，字符就互相靠拢了。但是这样做并没有改变疏密不同的情况，尽管mp已经是互相紧靠着密不透风，但pl还是有很大的距离。当然，如果继续减少字符间距也可以最终令pl之间也“密不透风”(设为-300左右)，但mp之间却会产生重叠的效果了。我们可以用一个简单的算式来理解：假设mp原来的距离为100，pl之间的距离为300，当字符宽度设置为-100的时候，mp之间的距离为0，pl之间的距离还有200。要令pl之间的距离为0，字符宽度必须设置为-300，但同时mp的距离必须为-200，所以mp产生了重叠的现象。比例间距选项的作用是同比例地减少(注意，只能是减少而不能增大)字符的间距。按照上一个算式中的前提来假设计算的话就是：当比例间距设为50%，相当于所有字符间距减半(mp间距为50，pl间距为150)，当设为33%的时候，所有字符间距减为原先的三分之一(mp间距约为30，pl间距为100)，当设为100%的时候，所有字符的间距就都被降为0了。因此我们看到的效果是所有字符都彼此依靠(抗锯齿选项及字体形式的不同可能带来微小差异)。1017间距微调选项是用来调整两个字符之间的距离，使用方法与字符间距选项相同。但其只能针对某两个字符之间的距离有效。因此只有当文本输入光标置于字符之间时，这个选项才能使用。1018竖向偏移(也称基线偏移)的作用是将字符上下调整，常用来制作上标和下标。正数为上升，负数为下降。一般来说作为上下标的字符应使用较小的字号。如下图。1019强迫形式的名称是我们为了与文字形式相区别而起的，它的作用也和文字形式一样是将字体作加粗、加斜等效果，但选项更多。即使字体本身不支持改变形式，在这里也可以强迫指定。它与字体形式可以同时使用，效果加倍(更斜、更粗)。其中的全部大写字母选项的作用是将文本中的所有小写字母都转换为大写字母。而小型大写字母选项的作用也是将所有小写字母转为大写，但转换后的大写字母将参照原有小写字母的大小。如下图所示。上标与下标选项的作用与竖向偏移类似，就是增加了可同时缩小字号的功能。下划线选项与删除线选项的作用是在字体下方及中部产生一条横线。
用PS完美抠出复杂的羽毛头饰的简单教程
打开如下图片，复制图层，将 背景 层锁定。我们将在复制层进行抠图，隐藏背景层。选择 >> 色彩范围，打开色彩范围窗口，选择最左边的吸管工具并点击图像背景，这时在色彩范围窗口中你会发现被选择部分变成了白色，移动颜色容差滑杆，使得图像大部分区域变成黑色，并且背景易于选取。提示：要添加颜色到选区时，应使用中间的吸管工具点击要添加的色彩部分2 获得选区，在通道面板中，按下“将选区存储为通道”按钮，得到一alpha通道，取消选择（Ctrl+D），点击“Alpha 1”层，这时图像变成黑白色。提示：图像中的黑色区域是我们要保留的部分，白色为要扣除的部3 这时我们发现图像中还有部分灰色区域，这些将成为半透明区域，所以必须将他们调整为纯黑色或纯白色。图像 >> 调整 >> 色阶，打开色阶窗口，由左向右拖动黑色滑杆直到灰色区域变为纯黑色为止。由右向左移动白色滑杆将白色区域变的更清晰4 选择黑色笔刷并提高笔刷边缘硬度，涂抹需要保留的区域，用白色笔刷涂抹羽毛边缘，根据涂抹区域大小的不同使用不同粗细的笔刷

Photoshop去斑教程
知道了以上4点以后。我们就要根据这几点来处正图像。让我们动手吧。：） 4.现在我们再来看一下，整体画面的亮度和面部的雀斑已经有所改善。但是皮肤部分，我仍然觉得有些暗，不够白。所谓一白遮三丑，想让MM的照片漂亮起来就让它白一点吧。（但也不要太过份哟）。我用钢笔工具，勾出皮肤的部分，再勾出眼睛嘴巴。只留下皮肤部分。羽化5。同样，用曲线工具，提高它的亮度。（我爱曲线工具） 5.接下来我们就来处理面部，使它看起来光滑，不粗糙。我用的方法是:复制一个新层为当前层，调出红色通道的选区（按Ctrl单击红色通道），按Ctrl+H隐藏选区。执行滤镜中的高期模糊。模糊度自己看一下皮肤表面的效果。。确定后。按Ctrl+D。取消选区。给此层增加一个图层蒙板。用橡皮工具，将眼睛，嘴，头发，等有细节的地方，擦掉。此时应该注意的有三点。图层透明度。笔刷大小。笔刷压力。 这三点可以自己适当调整。压力不益过大。 6.这一切做完之后。基本上也就算完成了修图。 7.但在这里我还要介绍一下用KPT channel surfing滤镜来完成第5步中高期模糊的任务。因为我觉得用它效果更好一些。让我们的思想再次回到第4步结束时。 同样，复制一层为当前层。执行KPT7中的channel surfing 滤镜。具体设置如下图。确定后。仍然图层用蒙板擦掉细节部分，漏出下层的细节。
将人物ps成雕像
最终效果图素材图1素材图2一、打开两幅素材图片，将人物抠图后放在背景层上，调整好大小和角度。二、在背景图层上用钢笔按人物边缘画出选区，激活后用涂抹工具向人物方向拖移，也可用图章来完成。 三、在人物图层上选叠加，人物面部就和背景的纹理融合了。
Photoshop通道磨皮去斑
3、用吸管工具吸取邻近的色然后用画笔覆盖如图所示的要保护的部分。包括眼、鼻、眉、嘴、发丝的阴影细节。 4、图像\调整\计算，生成Alpha1通道 。设置参数如图： 5、按住 Ctrl键用鼠标点击Alpha1通道载入选区，Shift+Ctrl+I反选。返回到图层调板点击激活背景层。然后建立一个曲线调整层，调整曲线，边观察图像的变化。此时不急于完全去掉斑点，只是将它们大幅度减弱。因为下面还要重复一次前面的操作。（新手注意直接按曲线的输出输入参数输入数值） 7、好，按Shift+Ctrl+Alt+E组合键盖印可见图层，对它重复一遍前面的操作。后面的操作参数凭自已的观察来进行。把握的原则是全部进行微量的调整。达到保持图像影调色调平衡，去斑效果更好的目的。完了？且慢！我们发现暗处有些黄色的色斑。包括脸上的发丝。在工具箱中取海绵工具，模式选项为去色。设一个较小的数值小心擦拭色斑。然后用画笔工具，选取邻近的颜色上色（画笔用颜色模式）。 教程的思路：运用“高反差保留”和计算突出斑点，用中性灰色限制对细节的改变并且平滑过渡。循序渐进，逐步减弱斑点。当然最终效果还不是最好的。你可以再对它进行调色等其它美化操作。
亦真亦幻：用PS创造红外摄影图片
红外摄影以其独特的魅力吸引了很多人的目光，SONY F717更以拍摄红外摄影图片著称。甚至有些发烧友会因此改造自己的相机！可见其吸引力确实不小，而今天我们就用PHOTOSHOP来创造你自己的红外摄影图片。 首先我们先研究一下红外摄影图片的成像原理： 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('UploadFiles/200602/20068555413734.jpg');}" src="/Files/photo/2007-4/2/074215444137638.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>图1 这是一张普通的风景照，颜色跟我们肉眼所见没什么区别。 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('UploadFiles/200602/20068555413621.jpg');}" src="/Files/photo/2007-4/2/074215444160423.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>图2 这是一张红外摄影图片，在红外摄影图片中红外线才是其可见光。其中反射红外线较多的物体如植物的叶子，天上的白云变的很亮。而吸收红外线较多的物体如天空，水则变的很暗。 好了，明白了红外摄影图片的成像原理。就让我们大干一番吧。1、打开PHOTOSHOP，然后打开刚才的风景图片。 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('UploadFiles/200602/20068555413371.jpg');}" src="/Files/photo/2007-4/2/074215444135690.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>图3 先建立一个新序列，然后在新序列中建立一个新动作。 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('UploadFiles/200602/20068555413112.jpg');}" src="/Files/photo/2007-4/2/074215444173251.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>图4 并都命名为红外摄影，最后点纪录。 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('UploadFiles/200602/20068555413833.jpg');}" src="/Files/photo/2007-4/2/07421544412850.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>图5 小技巧：建立新动作的目地是让以后相同的工作变的简单。在 Photoshop 中动作就象一个小机器人。它会记住你的操作步骤，然后在其它的图片上进行相同的操作。最重要的是你可以通过它对文件进行批处理。希望大家重视一下这个功能，它会让你事半功倍的。 2、打开通道混合器。 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('UploadFiles/200602/20068555413140.jpg');}" src="/Files/photo/2007-4/2/074215444137643.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>图6 将红绿蓝三色通道数值分别改成-66。+198。-66，并勾选单色。然后点"好"确定。 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('UploadFiles/200602/20068555414876.jpg');}" src="/Files/photo/2007-4/2/074215444136818.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>图7 这样做的目地是将红色及蓝色压暗，而将绿色提亮。从而极大的近似红外摄影的效果，达到以假乱真的目地。 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('UploadFiles/200602/20068555414436.jpg');}" src="/Files/photo/2007-4/2/074215444116878.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>图8 但现在图片是黑白的，下一步我们将它变成彩色的。3、复制背景图层，并将其放到最上一层。 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('UploadFiles/200602/20068555414884.jpg');}" src="/Files/photo/2007-4/2/074215444126845.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>图9 把图层混合方式改为叠加。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('UploadFiles/200602/20068555414954.jpg');}" src="/Files/photo/2007-4/2/074215444120532.jpg" onload="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('UploadFiles/200602/20068753558621.jpg');}" src="/Files/photo/2007-4/2/074215444964977.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> 我们可以使用“去色”命令将彩色图像转化为灰度图像，这样就可看到明暗的分布：天空部分属于高光，树木和草地属于暗调。 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('UploadFiles/200602/20068753558371.gif');}" src="/Files/photo/2007-4/2/074215444941617.gif" 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> 在曲线面板中那条直线的两个端点分别表示图像的高光区域和暗调区域，直线的其余部分统称为中间调，两个端点可以分别调整。 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('UploadFiles/200602/2006875360112.gif');}" src="/Files/photo/2007-4/2/074215444979533.gif" 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> 下面两幅动画演示了单独改变暗调点和高光点的效果，其结果是暗调或高光部分加亮或减暗。 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('UploadFiles/200602/2006875360833.gif');}" src="/Files/photo/2007-4/2/074215444997236.gif" 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> 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('UploadFiles/200602/2006875364140.gif');}" src="/Files/photo/2007-4/2/074215444920538.gif" 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> 而改变中间调可以使图像整体加亮或减暗（在线条中单击即可产生拖动点），但是明暗对比没有改变（不同于电视机的亮度增加），同时色彩的饱和度也增加，可以用来模拟自然环境光强弱的效果。 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('UploadFiles/200602/2006875366876.gif');}" src="/Files/photo/2007-4/2/074215444940555.gif" 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> 现在我们适当降低暗调和提高高光。 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('UploadFiles/200602/2006875369436.gif');}" src="/Files/photo/2007-4/2/074215444965071.gif" 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> 可以得到明暗对比较强烈的图像（所谓的高反差） 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('UploadFiles/200602/2006875369884.jpg');}" src="/Files/photo/2007-4/2/074215444935729.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> 但是这样做可能让较亮区域的图像细节丢失（如天空部分的云彩），同时这也不符合自然现象，此时可以通过改变中间调的方法来创建逼真的自然景观。 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('UploadFiles/200602/20068753610954.gif');}" src="/Files/photo/2007-4/2/07421544492971.gif" 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> 这样图像看上去就自然多了，不会有明显的改动痕迹。 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('UploadFiles/200602/20068753610572.jpg');}" src="/Files/photo/2007-4/2/074215444957623.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> 前面我们都是在整体图像中调整，现在我们来看一下单独对通道调整的效果，电子设备所产生的图像都是由红、绿、蓝三种色光按照不同比例混合而成，（近观彩电的屏幕，你就会看到无数个红绿蓝小点，电脑显示器也是如此但较精细），换句话说，在屏幕上展现的图像实际上都是由三个单独颜色的图像（红、绿、蓝）混合而成，所谓通道即是指这单独的红、绿、蓝部分，又称RGB。 如果我们单独加亮红色通道，相当于增加整幅图像中红色的成分，结果整幅图像将偏红。 如果我们单独减暗红色通道，结果图像将偏青，青与红是反转色（又称互补色），红和绿、黄和蓝也是反转色。 反转色相互之间是此消彼长的关系： 要加亮黄色，则减暗蓝色； 要加亮粉红，则减暗绿色； 要加亮金黄（金黄由红和黄组成），则需要同时加亮红色和减暗蓝色。 现在我们试试将天空部分的色彩改为金黄。由于天空属于高光区域，所以我们要加亮红通道的高光部分。 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('UploadFiles/200602/20068753611148.gif');}" src="/Files/photo/2007-4/2/074215444956277.gif" 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> 同时减暗蓝色通道的高光部分。 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('UploadFiles/200602/20068753611521.gif');}" src="/Files/photo/2007-4/2/074215444944589.gif" 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> 这样我们就得到了金黄色的天空效果。 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('UploadFiles/200602/20068753611660.jpg');}" src="/Files/photo/2007-4/2/074215444928921.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> 这样的效果虽然绚丽，但是仔细看远处的青山也变成了黄色，山体应该属于中间调部分，所以我们在红色和蓝色通道中将中间调保持在原来的地方。 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('UploadFiles/200602/20068753612337.gif');}" src="/Files/photo/2007-4/2/074215444926071.gif" 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> 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('UploadFiles/200602/20068753612846.gif');}" src="/Files/photo/2007-4/2/074215444984767.gif" 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> 这样我们就得到了金黄的天空，同时也保留了远处山体的青色 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('UploadFiles/200602/20068753613630.jpg');}" src="/Files/photo/2007-4/2/074215445060288.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> 从上述例子可以看出，使用曲线工具可以进行非常全面的色彩调整，就数码后期处理（并非艺术创作）而言，应该可以应付绝大多数的情况了。
