这篇帖子的动机来源于版上对锐化的提问及讨论帖：
http://www.mitbbs.com/article_t/PhotoGear/35032079.html
锐化是一项对最终成片效果影响很大的后期技术，尤其是当成片要打印或上传到各种对
尺寸要求有严格限制的网站分享时。锐化技术本身并没有多少难度，但如何正确地应用
在不同场合和不同需求，当中的技巧却不是每个人都知晓的。我想通过这篇文章对PS锐
化技术从原理到应用上有个比较全面的介绍，然后让读者自己思考之前自己所用的锐化
技术是否合理，应当采用哪种技术进行改进。这将是一篇比较枯燥的技术文，因为时间
和MITBBS排版问题的限制，我不打算贴图来解释说明。也许以后有时间了会补上更生动
的例子。

who sharpens every dull
here comes the only man
reminding with his bell
to disappear a sun
and out of houses pour
maids mothers widows wives
bringing this visitor
their very oldest lives
one pays him with a smile
another with a tear
some cannot pay at all
he never seems to care
he sharpens is to am
he sharpens say to sing
you'd almost cut your thumb
so right he sharpens wrong

if the skate is not sharpened, it can not hold the ice, so it is very easy

发帖数: 35 | 38 you can use either of them.
but based on general procedure of image process, you should apply the
SHARPEN on your last step, which means most likely you do sharpen on PS.
I assume you adjust exposure/white balance ect.. on raw, then open in PS for
more enhancements.
for landscaping picture, you can apply sharpen for entire pic. for portrait,
it requires to apply this effects in certain areas, so MASK is an important
tool. |

“基本步骤其实很简单，把虚的人物抠图出来，用photoshop里面的sharpen工具锐化，
sharpen的参数要多试几次，不够的话都sharpen几次。最后背景稍微blur一点点，一方
面看起来真实一点，另一方面也人为造成反差，让人觉得前景中的人物清晰一点。”
