同感。”ul的既不容易感觉到咬钩“--应该是“ultra light/medium action"的不容
易感觉到咬钩 :)
ultra light搏大鱼的问题是杆不够硬,不够力,控不住鱼,使不上劲,很难将大鱼暴
力拉上来。这跟用Medium Heavy/Heavy的杆钓小鱼的问题正好相反:杆太重,饵太重
,鱼太小,拉着使不上劲,不过瘾。

有的时候,杆不需要太敏感,太敏感反而不好。比如,用Bait钓鱼时,等它完全吞
了再SetHook也不迟,太敏感的杆反而容易造成Set Hook太早,将饵从
鱼口中拉出来了。
另外,敏感的杆一般是又硬又脆,不够柔软,不利于溜鱼。所以,钓猫鱼,鲤鱼,不太
合适。钓这些鱼,用Medium Action, Medium Power,溜起来更爽。
当然,用假饵的话,因为鱼容易吐饵,一般还是用敏感的Fast/Extra Fast杆较好。
Power的话,钓Crappie可用Light/Medium Light. 钓Bass的话,可用Medium.
一家之言,Take with a grain of salt.

来自主题: GunsAndGears版 - 求教AR上按flashlight/weapon light的意义
我经常看到别人(不是本版版友)的AR照片上有安flash light,我一直想不明白,这
个除了是eyecandy,bling facotr到底有什么实际意义。
说实话看起来很酷,我第一次见到M4就是在Black hawk down里边的delta小队,全都是
M4提把上按scope,前边安个flash light,但那是打仗。
家防?AR感觉不是很好的HD选择。打靶,除非经常晚上去靶场还没灯,激光?100yd能
散射成啥样啊,唯一能想到的就是挂在barrel上减少recoil,可是AR recoil已经很少
了。
像sure fire很多flash light都四五百块,快赶上一个sporter AR了。
因为我周围没什么朋友玩AR,是不是又我没考虑到的功能,请大牛指点

跟朋友计划去阿拉斯加,结果两人都买了coupon book。
有人需要吗?需要的话我转一本全新的,一页未少,刚拆封:P
原价50+7块钱运费。有人要的话就40块钱拿走吧,免运费。
Northern Lights coupon book的官网是http://www.northernlightscouponbook.com/
可以在coupon offers里查看它有哪些coupon。
alaska有两种coupon book,一本50块钱的northern lights,一本100块钱的tour
saver。选择northern lights是因为它有很多anc城里吃饭的coupon,同时有好几个租
车公司buy 1 get 1 free的coupon,这些tour saver都没有,而我们要三次经过anc,
对我们来说比较实用。至于用它来省钱的游玩项目,比如kenai fjords cruise,两者
都有。

来自主题: PhotoForum版 - continuous lighting VS flash lighting
my two cents
Flash lights (strobe) are much better. Even newer continuous LED lights are
getting cheaper, they should only be considered if you want to also shoot
video in a studio setting.
SB800 is a good flash to carry around. But its pretty much useless in a
studio context once you have two or three strobes.

Suited for motion picture, broadcast, and still photographic markets, low-
light polarizer facilitates shooting indoors in low-light conditions and
situations that do not provide enough light for standard polarizer. Product
reduces glare and reflections, saturates colors, and maintains contrast
without compromising image quality.
估计没其他区别。

Master Lu Tzu said: Since when has the expression "circulation of the Light"
been revealed? It was revealed by the "true men of the beginning of form".
When the Light is allowed to move in a circle, all the powers of Heaven and
earth, of the light and the dark, are crystallized. That is what is
described as seed-like, or purification of the power, or purification of the
concept. When one begins to apply this magic, it is as if, in the middle of

Explanation: Light is more complicated than we thought. When astronomers measure light, they are usually
concerned with its direction, energy, and spin polarization (sometimes). Recently, however, it has been more
broadly realized that photons can also have orbital angular momentum (OAM), an attribute classically analogous

哦。
简单解释一下吧:light load和heavy load不仅是load轻重问题,而且是因为通常
这么说,是因为工作的模式不同。two modes, one for light load, one for heavy
load.
所以一般说light load,是指不仅轻载,而且工作模式也是叫DCM mode, heavy load则
不仅是重载,模式也是叫CCM mode
你只要知道这里就差不多了。再往下去,我觉得你真的没必要一定懂,特别是初级阶段。
