When you overexpose your film, you are exposing for the shadows, which

It could be the lack of contrast. With limiated tonal viaration of those GC

single focus point when zoomed out, and vice versa. A couple of things you
could try though:
1. Set the focus point to the upper edge of the mountain so that the small
piece of sky in the focus point can provide ample contrast for focusing.
2. Switch to AF-S. I usually avoid using AF-A because the mode allows the

fuji官方对classic chrome的说法是:低饱和,较高反差(阴影高反差、高光低反差),
消洋红,控红绿(我感觉是红相往洋红偏、降饱和,绿相往蓝偏、降饱和)。

来自主题: PsychoAnalysis版 - 一个人怎么快乐起来
也许是你已经很麻木了?很适应了那种生活。
温水竹青蛙的生活,呵呵。。
人类幸福的秘诀在于神经网络的adaptation.
不幸的来源在于心理上的contrast effect.
如果无论发生什么,都定义现在=happiness,
丢弃contrast effect,比如通过自我暗示或者宗教的力量
那么自然可以知足常乐,同时也 == 醉生梦死。
一切都是双刃剑。
人生的欲望就是一个个钟摆,
adpation和contrast effect的双重作用下
在绝望和希望之间摇摆
有的摆得快,有的摆得慢。

来自主题: TrustInJesus版 - 再来提问一个信奉的问题

回应:
一、注意“长老”不是“老年人”可能是年轻人或中年人。请长老抹油祷告是很正常的
,任何相信圣经的教会都会有人相信并实践的。
二、我不清楚怎样解释‘“圣经”“新约”明确要求女人在教会要“闭口不言”’。
我不知道这个教导是不是绝对的,或“明确”。
例如,哥林多前书十一章,
4 凡男人祷告或是讲道(讲道或作说预言下同),若蒙着头,就羞辱自己的头。 5 凡
女人祷告或是讲道,若不蒙着头,就羞辱自己的头。因为这就如同剃了头发一样。 6
女人若不蒙着头,就该剪了头发。女人若以剪发剃发为羞愧,就该蒙着头。
这些经文意为,女人可以讲道(先知预言)只有蒙头(要不就剪头发)就可以了。与哥
林多前书十四章34-35节的教导有异。我没时间具体查原文希腊文怎么写的。
在网上找到一篇有关文章。(比较长)

大部分人看到一个好的搭配,第一个反应一般都是“好看”,“有气场”,“气质好”
,但是为什么好看,却说不出道理。

来自主题: Apple版 - 说说我当年为什么没买ipad

Kindle的白底黑字 对比度 contrast ratio 只有 10:1 ,我发现 看超过10分钟,眼睛
就觉得很累 很stress.
普通LCD都是1000:1的contrast ratio. 但pixel density 一般只有100 pixels per
inch, 而kindle做到了150-167 ppi.
我还是宁愿看纸书,黑白contrast ratio 高, 而且绝对是 500 甚至1000 ppi以上的显
示精细度。目前的 e-ink technology (Kindle, Sony reader, Nook all bought the
e-ink tech from the same company) 我觉得还是不成熟,将就着用个几分钟
还凑活而已。

Tesla on Edison: "If he had a needle to find in a haystack he would not stop
to reason where it was most likely to be, but would proceed at once, with
the feverish diligence of a bee, to examine straw after straw until he found
the object of his search. ... I was almost a sorry witness of such doings,
knowing that a little theory and calculation would have saved him ninety per
cent of his labor."
