Photoshop复杂图像抠图技巧

对于边缘复杂、块面很碎、颜色丰富、边缘清晰度不一、影调跨度大的图像,最好是用蒙版来做抠图。

下面这张图是一位在大自然中的写生者,背景不好,需要替换。要把人物和地面抠出来,路径、魔棒、套锁、通道都不好用,还是用蒙版吧。

我把那张素材照片也放在这里,方便大家做练习。

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('//img.sj33.cn/uploads/allimg/200605/20060526232339772.jpg');}" src="//img.sj33.cn/uploads/allimg/200605/20060526232339772.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>

1、制作的时候一定要精细,不断地调整笔刷的直径和软硬参数,不能凑合;

2、蒙版是可以修的,发现那里不合适,就重新进入蒙版作修饰;

3、如果整体图像都带有一个边缘,可以在蒙版中做一个像素的minimum处理。

再说一下钢笔抠图的好处与坏处。钢笔抠图适合边缘整齐的图像,这个图像中的草地边缘用毛笔来做就比较方便。另外,钢笔抠图所产生的蚂蚁线都是不带羽化值的,而有些图像中的边缘时软时硬,比如运动的手臂边缘是虚的,这时候用软笔刷来做就尤其方便了。这是钢笔路径做不到的。
