发帖数: 25662 | 2 raw下一般先处理白平衡。
noise reduction 和 sharpening可以是最后两步。
有lightroom 3可以不许要把noise ninja加到workflow了。用lr直接在raw下降噪。lr
的降噪在保留细节上做得比ninja要好。
锐花要求不高可以直接用lightroom的，可以试一下sharpening里那个mask拨杆，有时
候会有惊喜。
锐花要求高的，lr导出tiff进photoshop局部细节锐化，否则在lr直接导出jpeg时可以
最后再选择jpeg的锐花，我一般选screen。 |

发帖数: 1173 | 11 磨刀通则：
１、不管磨什么刀或用何种工具（Lansky, Spyder., 磨石…whatever），磨刀第一要
件就是磨时要保持刀刃的固定刃角，这需要练习，但有一个老手都知道的小窍门就是磨
前先用奇异笔先将刀的开刃区涂黑，再拿去轻磨几下后，检视刃区，若角度正确，则黑
色将完整被磨掉，若否，自己观察Mark区后调整角度，抓到角度后就将感觉记起来，
后续依此感觉磨刀。此方法新老手都适用，因为不同刀有不同角度，就算是专业磨刀师
可能也要依不同刀之角度来调整感觉。
说到这边，有一个迷思大家可以思考，是否每一支刀都要保持原出厂时的开刃角？从收
藏者观点，此点勿庸置疑。但从使用者观点，我倒觉得值得商榷，我通常会依照自己的
用刀习惯，来改变刃角，使刀能 在手中做到最大的应用，但前提还是「就算你要改变
刃角，你还是要保持固定改变后的刃角角度」。
２、当你可以在磨刀时固定刃角后，开始进入最关键程序了：磨的程度。磨刀是一种削
薄磨去刀刃材料以制造新的锋锐刃区（edge）过程，因此磨石的功能就以此为依归，粗
磨是进行上述过程，制造出锋刃 ，细磨是去除粗磨过程中产生的毛边，光则是更进一
步加强细磨的功能。由... 阅读全帖 |

输出的时候就有颜色washout还是上传flickr后有?
flickr上我现在开始上传的都是长边1000的照片.主要因为每个人用的电脑大小不同,
1000长边保证了大部分电脑,特别是笔记本电脑上观看,都不会缩图.如果上传1200或者
1600的,台式机大屏幕上看是没问题,但笔记本上看就会自动缩图,锐化效果就不好了.如
果上传的是4000*6000,那么无论什么电脑看基本上边长都得缩至少一倍多,锐度就大大降
低了.

随后在知乎上有律师发表了自己对周立波持枪的看法：各位，我个人非常赞同涉毒公众人物应受到比普通人更加严厉的制裁，但在本案中，还是不要过于乐观。15年刑期仅仅是理论可能上的最乐观估计，事实上，即使五项指控中最重的一项成立，周立波面临的刑期最低也有可能低至三年半。
首先，我们看看周立波受到了哪些指控：持有违禁药品（轻罪），二级非法持有武器（C级重罪），驾驶过程中使用手机（轻罪），非法持枪（E级重罪），四级非法持有武器（轻罪）。
检方很贴心地标记出来，二级非法持有武器罪是其中最重的指控，我们先来看看：
纽约州刑法（New York Penal Law）265.03条列举了构成二级非法持有武器罪名的三种情形，从媒体报道的情况和检方公布的起诉信息来看，周立波被指控的依据应该是第（3）款，在住宅和工作地点以外的场所持... 阅读全帖 |
