★。黑白照片の彩色秘密

<P><FONT size=3>黑白照片，怎么会变彩色呢？但看看下面这幅图，你看着是灰色调的，但你尝试着用鼠标拖动，选择一下看看？<BR><IMG 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('http://www.missyuan.com/psoto/20060909/001/20050501020450_1.jpg');}" src="http://www.missyuan.com/psoto/20060909/001/20050501020450_1.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><BR>嗯，我想你发现了，这图变成彩色了。神奇吧？这个原理是很简单的，首先我要从选择图时的处理方法讲起。在选择图片的时候，浏览器会把图片像素按间隔填充交错填充深蓝色。如下图。<BR><IMG 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('http://www.missyuan.com/psoto/20060909/001/20050501020459_2.gif');}" src="http://www.missyuan.com/psoto/20060909/001/20050501020459_2.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><BR>为了促进理解，请选择下图。<BR><IMG 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('http://www.missyuan.com/psoto/20060909/001/20050501020509_3.gif');}" src="http://www.missyuan.com/psoto/20060909/001/20050501020509_3.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><BR>哈哈。图像消失了是吧？变成了一团灰色。嗯，这就是选择时把所有有颜色的点全填充成一个深蓝色的原因。<BR>这时候有人问了，就算是这样，为什么我们看到的图是黑白的呢，原来交错点上的也会是彩色的啊？<BR>这个问题问的好，因为我们对交错点进行了180度的色相处理，也就是我们处理成了他的互补色，补色混合后，就呈现灰色了。我们的眼睛灰自动把他们处理成灰色了。<BR>看下面两图，其实他们在选择的时候，效果是一样的。实际上，只要做出图四的样子出来，剩下的点是什么颜色根本无所谓，把剩下的点改变色相的目的，只是为了欺骗你的眼睛。<BR><IMG 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('http://www.missyuan.com/psoto/20060909/001/20050501020450_1.jpg');}" src="http://www.missyuan.com/psoto/20060909/001/20050501020450_1.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><BR><IMG 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('http://www.missyuan.com/psoto/20060909/001/20050501020538_4.jpg');}" src="http://www.missyuan.com/psoto/20060909/001/20050501020538_4.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><BR>明白了原理后，现在做起来就容易了。我们现在就要来熟悉Fireworks中，怎么来制作这样的特殊图片。<BR>打开原图，做一些减少色彩纯度的处理，因为颜色对比强烈时，互补色呈灰效果不是很好。<BR><IMG 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('http://www.missyuan.com/psoto/20060909/001/20050501020556_5.jpg');}" src="http://www.missyuan.com/psoto/20060909/001/20050501020556_5.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><BR>复制原图到新的一层。<BR><IMG 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('http://www.missyuan.com/psoto/20060909/001/20050501020609_6.jpg');}" src="http://www.missyuan.com/psoto/20060909/001/20050501020609_6.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><BR>画一个和图一样大的方框，填入黑色，纹理选择grid3 选择100%的纹理填充。<BR><IMG 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('http://www.missyuan.com/psoto/20060909/001/20050501020618_7.gif');}" src="http://www.missyuan.com/psoto/20060909/001/20050501020618_7.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><BR>选择 modify &gt;flatten selection (中文的可能是 修改&gt;合并选择)，把当前这个黑白交错的图案变成 <BR>bitmap(位图)，目的是为了让他能成为灰度蒙版。<BR>选择这个黑白图，ctrl+x 剪切它。然后选择上面的原图，选择菜单 modify &gt; mask &gt; past as mask (中文可能是 <BR>修改&gt;蒙版&gt;粘贴为蒙版)如下图。<BR><IMG 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('http://www.missyuan.com/psoto/20060909/001/20050501020629_8.jpg');}" src="http://www.missyuan.com/psoto/20060909/001/20050501020629_8.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><BR>这一步的目的是建立一个灰度蒙版，也就是根据蒙版的灰度，来确定显示的百分比，黑色就不显示，白色就全显示。这样，我们就做出了我们想要的交错点效果了。你可以点击图层面板中下面一图的眼睛标识，来看你做出来的效果。<BR><IMG 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('http://www.missyuan.com/psoto/20060909/001/20050501020641_9.gif');}" src="http://www.missyuan.com/psoto/20060909/001/20050501020641_9.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><BR>关键的一步，就是反向了，选择我们的蒙版图层，然后从菜单， filte &gt; adjust color &gt; hue/saturation.. <BR>(中文可能是滤镜&gt;调节颜色&gt;色相/纯度..)，把色相的调节值改为-180。<BR><IMG 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('http://www.missyuan.com/psoto/20060909/001/20050501020659_10.gif');}" src="http://www.missyuan.com/psoto/20060909/001/20050501020659_10.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><BR>基本上现在导出的图，就差不多了，如果灰色的效果不明显，还可以把纯度调低，或者把图变亮一些(因为交错点填充是深蓝色)，导出时减少压缩，增加一点smothing(平滑)。这样会有更好的效果。反正，剩下的事就是大家去发挥了，这是最后的效果了。</FONT><BR><IMG 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('http://www.missyuan.com/psoto/20060909/001/20050501020714_11.jpg');}" src="http://www.missyuan.com/psoto/20060909/001/20050501020714_11.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true;
