photoshop中抠图方法的研究与应用.doc

中文摘要
抠图是图像编辑的基础,不论是照光修饰,还是平面设计,只要用到素材,就离不开抠图。在实际工作当中,需要进行抠图的图象有很多种,有的很难,有的很简单,也有很多种方法,魔棒、通道、蒙板、套锁等等。但无论采用什么样的方法,其实也都是尽量让被抠图的图与背景的边缘更清晰,更方便分离出来,以便我们能获得想要的图形的选取。所谓Photoshop抠图,就是将要与不要的图形区分开,也可以说:抠图的本质是图象分离。将选中的部分分离出来用来做其他的事情。本文通过对photoshop中抠图的方法与技巧的实验与总结,理解并掌握了不同抠图方法的应用范围,得到以下结论:路径适合做边缘整齐的图像,魔棒适合做颜色单一的图像,色彩范围适合做背景色单一的图像,套锁适合做边缘清晰一致能够一次完成的图像,通道适合做影调能做区分的图像,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。
