利用Photoshop脚本功能制作清晰的景深风景图
景深，就是清晰的范围。风光摄影，一般都需要从近到远都清晰。静物摄影，一般距离比较近，多用中长焦段和微距镜头。这种情况下，即使使用了一个极小光圈，仍然不能把拍摄物体整体都拍清晰。针对这样问题，飞侠来结合案例，和大家说下如果拍出一张景深极大的作品。案例一：静物拍摄珍珠项链如果打算把这条项链，整体都拍清晰，我们是否可以通过一个小光圈就可以呢?大家来实际看看吧。我使用105mm微距镜，f22的小光圈。可是实际的景深效果呢?只是第一张对焦范围内是比较清晰的，其它二张的前景和远景图片都是模糊的。尽管使用了f22小光圈，拍摄物体还不是全部清晰。而且使用了这么小光圈，会导致画质下降。

CSS应用基础教程(2) 应用方式
Ｃ Ｓ Ｓ 的 声 明 方 式 这章节将开始为您介绍ＣＳＳ的应用。当然一开始要介绍的是如何去建立个样式表 （Style Sheets），包括了声明的方式和应用在网页上的方法，最後还会为您概述一下ＣＳＳ的一些特性。概略来说，ＣＳＳ的声明有三种方式：一、基本声明：最典型的ＣＳＳ声明方式。 element {property: value} 用中文来表示的话，也就是元件(标签) {性质(属性)名称: 设定值}例如： H3 {COLOR: BLUE} 即为一组声明。二、集体声明：同时声明某个或数个元件(标签)（各元件(标 签)间以逗号分隔）的一组或数组样式规则(性质)（各组规则间以分号分隔）。 元件(标签) {性质(属性)名称1: 设定值1;性质(属性)名称2: 设定值2;... }或是元件A(标签A), 元件B(标签B), 元件C(标签C), ... {性质(属性)名 称1: 设定值1;性质(属性)名称2: 设定值2;...}例如： TD {COLOR: BLUE;font-size: 9pt;}或是TD,P,DIV {COLOR: BLUE;font-size: 9pt; }三、分项声明：将许多样式规则分组再分别声明。 元件A(标签A) {性质(属性)名称1: 设定值1; 性质(属性)名称2: 设定值2; }元件A(标签A) {性质(属性)名称3: 设定值3; 性质(属性)名称4: 设定值4; }例如： TD { COLOR: BLUE; font-size: 9pt}TD { font-family: "标楷体"; line-height: 150%}这样子的声明方式并不会互相抵触，因为所声明的性质是不同的。如果不小心对同样一个性质作了重复的声明，则只有後来声明的设定值才会发生作用。 要附带提一下的是，在您的声明中，只要您的格式正确就会被接受，而不论是大小写、空白或换行都不会对显示的结果 有影响的，您可依自己习惯来编写。 Ｃ Ｓ Ｓ 的 应 用 方 法 接下来要为您介绍的是将所建立的样式表应用在网页上的四种基本方法。一、使用STYLE属性： 将STYLE属性直接加在个别的元件标签里。 <元件(标签) STYLE="性质(属性)1: 设定值1; 性质(属性)2: 设定值2; ...}例如： <TD STYLE="COLOR:BLUE; font-size:9pt; font-family:"标楷体"; line-height:150%>这种用法的优点 是可灵巧应用样式於各标签中，但是缺点则是没有整篇文件的『统一性』。二、使用STYLE标签： 将样式规则写在<STYLE>...</STYLE>标签之中。 <STYLE TYPE="text/css"><!--样式规则表--> </STYLE>例如： <STYLE TYPE="text/css"><!--BODY { color: BLUE; background: #FFFFCC; font-size: 9pt}TD, P { COLOR: GREEN; font-size: 9pt}--></STYLE>通常是将整个的 <STYLE>...</STYLE>结构写在网页的<HEAD> </HEAD>部份之中。这种用法的优点就是在於整篇文件的统一性，只要是有声明的的元件即会套用该样式规则。缺点就是在个别元件的灵活度不足。三、使用 LINK标签： 将样式规则写在.css的样式档案中，再以<LINK>标签引入。 假设我们把样式规则存成一个example.css的档案，我们只要在网页中加入
Maya UV和UV编辑实例系列(4):使用Fix Texture Warp选项
选择NURBS模型，打开属性编辑器，在Texture Map栏中打开Fix Texture Warp选项，可以对纹理的不均匀分布进行修正。而不需要依赖于NURBS表面的UV参数，Grid Div PerSpan U、Grid Div Per Span V、表示U向和V向每跨度的、分割数目，默认数值是4，数值越大纹理分越均匀。 打开Fix Texture Warp选项后，操作视图不能实时显示出来，只有渲染后才能看到。 应用Fix Texture Warp选项后渲染后，与左图相比，纹理虽然有拉伸，但分布相对均匀。 虽然纹理分布均匀，但还是有拉伸，这是应为我们使用的是1：1的纹理贴图，而闹钟壳的NURBS面片长宽比不是1：1。下面进一步调整NURBS模型的纹理，是其比例正确。 在Hypershader窗口中，选择模型的place2dTexture节点，打开属性编辑器，调整Coverage的数值，同时察看渲染视窗的更新效果，使用IPR渲染可快速看到调整结果，直到棋盘格看起来变为正方形为止。 根据IPR渲染结果，判断纹理贴图使用范围，从上面的例子可以看到纹理只使用整个面

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.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>图10 不透明度改为35% 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/200602/20068555414572.jpg');}" src="/Files/photo/2007-4/2/074215444129979.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11 好了关闭动作纪录按钮。 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/200602/20068555414148.jpg');}" src="/Files/photo/2007-4/2/074215444164999.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12 看一下自己的红外摄影作品吧。 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/200602/20068753517337.jpg');}" src="/Files/photo/2007-4/2/074215444946254.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true;

数码图像快捷曲线调色法
在Photoshop中打开图像之后，我们可以使用快捷键 CTRL+ M 调出曲线调整功能。 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/200602/20068753557734.gif');}" src="/Files/photo/2007-4/2/074215444958473.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> 在使用曲线调整功能之前，我们先简单介绍一下曲线工具的原理。Photoshop把图像大致三个部分 ：暗调、中间调、高光。比如下面这幅图像： screen.width*0.7) {this.resized=true;
