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>

   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/200602/20068555414521.jpg');}" src="/Files/photo/2007-4/2/074215444155336.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13
  
   4、再打开一张照片。点选刚才录制的动作，点播放。
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/200602/20068555414660.jpg');}" src="/Files/photo/2007-4/2/074215444161031.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14
  
   点选刚才录制的动作，点播放。
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/200602/20068555415337.jpg');}" src="/Files/photo/2007-4/2/074215444268999.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15
     好了，又一张红外图片出炉了。
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/200602/20068555415846.jpg');}" src="/Files/photo/2007-4/2/074215444246518.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16
  
   现在，我们已经学会了利用通道混合器来制作红外摄影作品了，还了解了Photoshop
中动作的用处。我们所用的这种方法。对于有着大海蓝天绿树白云的风景图片，绝对可以营造一种梦幻的气氛。
