AI可以在图形上应用类型于PS中图层蒙版一样的效果，也就是在理论上说，可以制作任何形式的透明变化，
精彩教程：如何画真实的月夜照片处理
。附一个小例子。
1-在深色图形上方制作圆形
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('/Article/UploadFiles/200602/200692661818734.jpg');}" src="/Article/UploadFiles/200602/200692661818734.jpg" nload="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>
2-“透明面板”和PS相似 也有混和方式和透明度的调节现在的白方块是当前选中的物体（实际里面是上述白色的圆形）
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('/Article/UploadFiles/200602/200692661818621.jpg');}" src="/Article/UploadFiles/200602/200692661818621.jpg" nload="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>
3-右上角三角号 开始制作蒙版
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('/Article/UploadFiles/200602/200692661819371.jpg');}" src="/Article/UploadFiles/200602/200692661819371.jpg" nload="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>
4-出现如同PS一样的蒙版 蒙版的原理也是白色显示当前图形的颜色 黑色遮挡当前图形的颜色同理不同的灰色即是不同程度的透明
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('/Article/UploadFiles/200602/200692661819112.jpg');}" src="/Article/UploadFiles/200602/200692661819112.jpg" nload="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>
5-点击右侧蒙版 看到蒙版方块出现很粗的黑色边框 说明现在开始在蒙版内工作了在蒙版上建一个图形 位置偏右一点
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('/Article/UploadFiles/200602/200692661819833.jpg');}" src="/Article/UploadFiles/200602/200692661819833.jpg" nload="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>
（此时状态类似于CDR中在容器内编辑一样 如果回到正常状态 再点左侧的图形方块）
6-在蒙版中的图形做一个径向渐变 可以看到原图白色的圆形右侧出现模糊 实际上这个模糊是透明效果
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('/Article/UploadFiles/200602/200692661819140.jpg');}" src="/Article/UploadFiles/200602/200692661819140.jpg" nload="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>
7-点左侧的图形方块 回到正常做图状态 可以把背景物体（在这里是一个矩形）应用一点渐变网格 或者其它别的变化
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('/Article/UploadFiles/200602/200692661819876.jpg');}" src="/Article/UploadFiles/200602/200692661819876.jpg" nload="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>
8-形成月亮与雾的效果
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('/Article/UploadFiles/200602/200692661820436.jpg');}" src="/Article/UploadFiles/200602/200692661820436.jpg" nload="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>
9-AI还有一个比较优越的操作 是制作物体混和（CDR中称调和）时 两个物体可带有透明度，如星星是用一个小星和一个大星的混和
大星为完全透明中间光亮理同制作月亮
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('/Article/UploadFiles/200602/200692661820884.jpg');}" src="/Article/UploadFiles/200602/200692661820884.jpg" nload="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>
如果进一步变化，月亮上还可以填加渐变网格或图案等，也可以对一组物体制作一个共同的蒙版，也可以对蒙版中的图形进行渐变网格或多图形混和等操作，
