1. Sand to 220 on the wheel.
2. Wet the pipe. If there are still scratches, return to step 1 and repeat. If there are no scratches move on to step 3.
3. Sand with 400 on the wheel. This wheel should be soft and leave few to no facets.
4. After sanding on the wheel with 400, sand by hand with a worn out piece of 400 (or you could use 500).
5. Apply the dark stain until it’s basically opaque.
5. Buff the dark stain off evenly using brown tripoli. If there are any remaining scratches, buff them out now.
6. Sand again using the same piece of worn out 400. You should be wearing a cotton glove on your non sanding hand or the sweat from your hand will reanimate the stain dust and put color back on the pipe. This is the most important step to achieve high contrast, so sand carefully and evenly.
7. Stain over the dark stain with a lighter stain (I usually use Yellow) and try to do it in one single pass. Do not overlap your strokes if you can avoid it or you’ll lift the dark stain and create one uniform mottled color. You don’t want that.
8. Take the same pipecleaner, dip it in a little shellac that’s been cut with alcohol and apply a single coat of shellac to the pipe. You can let it set up and dry, or you can wipe it off. If you wipe it off, though, you’ll lighten the color significantly.
9. With a different tripoli wheel that’s very lightly charged with compound, buff the pipe lightly. You should not remove any color, here. It should just give the pipe a nice even shine.
10. Buff with white diamond.
11. Buff with wax at around 650 RPM’s. If you buff at a higher speed with wax, you’ll need to buff with a clean wheel afterwards to even the finish.
*Steps 8-11 must be done while wearing gloves or you’ll never get a deep glossy finish.

起源
1919年5月4日，北京的青年学生为了抗议巴黎和会中，列强肆意践踏中国主权把德国在山东的权益转让给日本，举行了声势浩大的游行示威，最后发展成为以青年学生發起的学生运动和广大群众、市民、工商人士等中下阶层广泛参与的一次示威游行、请愿、罢课、罢工、暴力对抗政府等多形式的爱国运动。
1939年，在纪念五四运动20周年的时候，陕甘宁边区西北青年救国联合会决定5月4日为中国青年节（又称“五四青年节”）。1949年，中华人民共和国政务院正式宣布5月4日为中国青年节，但并非全民假日，仅14至28周岁的青年可放假半天[1]。在香港、澳门主权回归后，五四青年节虽没有成为法定公众假期，但亦在港澳两地逐渐举办了些纪念性活动，如金紫荆广场五四升旗礼[2][3][4]。
在台灣，青年節則於1954年時改訂為「三二九青年節」，以紀念1911年廣州黃花崗起義殉難的青年烈士。

等了两周，终于等到了我的第一支丹麦斗 Ben Wade，不是出自大牌之手，但也很有名气。谁叫俺没什么米呢，弄不起大牌。
此斗是二手，从Ebay购得。品相不错，纹理漂亮，斗型优雅。
到手后经过仔细观察，发现斗钵内部涂了一层碳层，可能是卖家后涂的。
斗体有光泽，有一两处磕碰，这个倒没什么，不影响大局。
开斗，抽的第一都是Billy Budd。风路通畅，毫不费劲，虽然开口并不是也很大。
稍有积水现象，通几次通条便可解决。以后可能会略加改动。。

刚才收到了一个从美国来的包裹,是我新买的”玩具”: Rolleimeter 3.5 禄莱裂相对焦器.
在光线较暗的情况下使用应该很方便.
这里有禄莱双反附件的说明，很有意思。

刚从平遥回来没几天，还没来得及从旅行的兴奋中解脱出来。
平遥这个地方，小城不大，充满了古香古色的气息，建筑美妙之极，让我不禁想，50年前的北京会是什么样子。现在，这也只能停留在想象中。
平遥这个地方，旅游的味道很浓，这也让我有一点儿小失望。各种纪念品，特产，假古董，到处都是。旅行者也到处都是。。。
平遥这个地方，商业味道也很浓，这也蔓延到了这次的影展。各种赞助的广告，产品的广告。让人感觉很不“艺术”。
平遥这个地方。。。。。。
最近在研究针孔相机，并想办法把针孔相机和古典技法结合起来。
正处在构思阶段。
发现了一个很好的网站。http://www.mrpinhole.com/calcpinh.php
可以通过这个网站来设计自己的针孔相机。
大家可以尝试一下。

为了方便各位老师使用各种不同片幅相机时候对镜头有个概念.也方便大家选择镜头.特摘录钱元凯老师写的<摄影光学与镜头>关于镜头焦距转换的一个表.
使用方法就是找到你使用的相应片幅,查到后面的系数,然后用现在镜头的焦距乘上系数就是折算到135相机的焦距.

6X9 0.43
6X12 0.34
4X5 0.28
5X7 0.21
8X10 0.14
例如,150镜头在4X5画幅上折算就应该是150 X 0.28=42MM 说明150在4X5相机上的视角相当于135相机42MM焦距的视角.
所以说其实4X5相机的标头应该是180头更加合适.因为180 X 0.28=50.4MM
昨天晚上，用了接近两个小时的时间，看完了IPhone 4的发布会。
用一个词来形容：精彩！！！
也让我对新一代的IPhone充满了期待。
Apple的工业设计，软件设计，都堪称一流，并具有前瞻性，让人佩服。。
让我很感兴趣的是他的拍照，已经视频功能。除了可以拍摄500万像素的照片之外，还可以拍HD视频。同时还可以在IPhone 4 上直接编辑，并马上分享。
这对于热爱摄影的人来说，是一个很好地记录工具。
要看发布会视频，到这里。。。

“跳影”（Jumpology），由Philippe Halsman (1906-1979)发明，是一种捕捉人或动物跳起瞬间的摄影形式。Halsman说：“当你要求一个人跳起来，他会全神贯注的跳，同时卸下了所有的伪装，为你展示真实的自己。”
很精彩的描述，同样精彩的照片。

古典摄影中文杂志，致力于交流与传播古典摄影技法。
让更多的人对这些古老的摄影技法产生兴趣，
并将其传播开去、发扬光大。
古典摄影技法主要指的是数码技术，及现代银盐技术出现之前，用于摄影创作的技法。
这些技法大多需要自己配制化学药品、涂抹感光剂、等复杂工序。
并可成像于多种物质和材质的表面。
从而得到与众不同的影响效果。
在这个快速发展的时代，到处都充斥着各式各样的数码产品，虽然快捷，但让人越发浮躁。
与之相反，古典摄影过程相对复杂，但给我们更多玩味的东西，同时也为艺术家们提供了一片崭新的创作天地。
