[photoshop]巨人影子!

本例中用到两张素材:一张是小男孩的照片，一张是巨人的卡通图片。
目的是把巨人做成小男孩的影子，做出夸张的视觉效果。

步骤:
一、抠出小男孩：在PS中打开小男孩的照片，经过观察发现小男孩有明显的轮廓，
所以不用考虑用什么特别的技法，用磁性套索就行。我试过直接用磁性套索来选，
发现比较困难，因为有的地方老走偏。有什么办法呢？想了想，根据磁性套索
的特性，我决定加强对比。具体做法如下：
A、按Ctrl+J把小男孩素材用复制一层，再按Ctrl+L对复制层进行调整，这里我
只对蓝通道进行调整，如下图示：

调整后得到如下图示的图片，对比有了明显的加强，

B、使用磁性套索前对它的属性做如下修改：

C、使用磁性套索

2007-12-5 12:18


得到如下图示的选区
[img]http://bbs.jcwcn.com/images/default/attachimg.gif[/img] [img]http://bbs.jcwcn.com/attachments/month_0712/20071205_6f8860670911663c97b1iCAKB5vYPeff.jpg[/img] [img]http://bbs.jcwcn.com/images/attachicons/image.gif[/img] [url=http://bbs.jcwcn.com/attachment.php?aid=675520&k=67ac2d02709e4eb676c5b8094bb73e62&t=1214266920&nothumb=yes][b][color=#0000ff]S5.JPG[/color][/b][/url] (34.99 KB)

D、修整选区，用套索工具，配合Shift加选Alt减选，对手、耳朵等细节部分进行修整。
最后再平滑1个像素，选区如下所示：
[img]http://bbs.jcwcn.com/images/default/attachimg.gif[/img] [img]http://bbs.jcwcn.com/attachments/month_0712/20071205_08e359e7c25c872990803gmxIrMbtHb7.jpg[/img] [img]http://bbs.jcwcn.com/images/attachicons/image.gif[/img] [url=http://bbs.jcwcn.com/attachment.php?aid=675521&k=1853f812daa5e4db4a5edb927af09aa3&t=1214266920&nothumb=yes][b][color=#0000ff]S7.JPG[/color][/b][/url] (35.02 KB)

E、保持选区，删除复制层，它的辅助任务已经完成。然后按Ctrl+J对背景层复制，小男孩
已经抠出来了，如下图示（为了便于大家观察我隐藏了背景层）：

呵呵！是不是很干净啊！
2、打开巨人图片，也用磁性套索，不过这次就不用那么麻烦了，因为这张图片的边缘对比很明显。

因为是做影子的，以选区的要求不是特别高，简单修整一下就行
[img]http://bbs.jcwcn.com/images/default/attachimg.gif[/img] [img]http://bbs.jcwcn.com/attachments/month_0712/20071205_8906ecaa9c68f22262a79CJPmoMARmYP.jpg[/img] [img]http://bbs.jcwcn.com/images/attachicons/image.gif[/img] [url=http://bbs.jcwcn.com/attachment.php?aid=675572&k=8ab8dc85adce8e8fd8327318c2e9e411&t=1214266920&nothumb=yes][b][color=#0000ff]S9.JPG[/color][/b][/url] (31.96 KB)

3、用移动工具把选项中的巨人拖到小男孩图片中，放在复制出来的小男孩下面：
[img]http://bbs.jcwcn.com/images/default/attachimg.gif[/img] [img]http://bbs.jcwcn.com/attachments/month_0712/20071205_0082dafe776c30332785L2iPExvKZzOo.jpg[/img] [img]http://bbs.jcwcn.com/images/attachicons/image.gif[/img] [url=http://bbs.jcwcn.com/attachment.php?aid=675573&k=97f745426417f4bd5316089a0260b701&t=1214266920&nothumb=yes][b][color=#0000ff]S10.JPG[/color][/b][/url] (26.86 KB)
2007-12-5 12:46


载入巨人的选区并填充为黑色

2007-12-5 13:41


4、按Ctrl+T，水平翻转，然后右键，选变形，对巨人进行变形

2007-12-5 13:42


5、执行：滤镜》模糊》高斯模糊，半径6左右

2007-12-5 13:44


6、最后再降低不透明度到60%左右，完成！
