color="red">大家知道这么原理吗？ ctrl+a全选后，就是给图片加上了一个黑白相间的蒙版<a href="http://bbs.16xx8.com/" target="_blank">。</a> 蒙版的白色部分是透明的，黑色部分是不透明的<a href="http://bbs.16xx8.com/" target="_blank">。</a> 这里就是利用了这一点，两个图像其实本来就同时存在于一幅图中的<a href="http://bbs.16xx8.com/" target="_blank">。</a>没全选时你看不到下面的人物是利用了大家的眼睛辨别精度有限这个缺陷，当全选时，蒙版中黑色部分盖住的正好是树林那一部分，所以树林看不到了,而那人物图的像素正好处于白色部分的范围，也就是透明范围，所以看到的只有人物了<a href="http://bbs.16xx8.com/" target="_blank">。</a> 还值得说明一点是：全选后蒙版总是从图片左上角的第一个像素开始蒙起的，所以在我们做图之前就该明白让哪层被蒙，又让哪层显露，心里该有个谱<a href="http://bbs.16xx8.com/" target="_blank">。</a>（附图） 还说一句：做好的图片在PS里是看不见效果的<a href="http://bbs.16xx8.com/" target="_blank">。</a>要贴上来，用ctrl+a全选后才能看见效果<a href="http://bbs.16xx8.com/"
