1. HSL space下所有的Hue都调低S（降饱和）
“The saturation is the lowest among all film simulations.
The saturation has been minimized to the limit.”
“The use of color is minimized and the tonality
becomes the main element.”
2. “with Classic Chrome we moved in a different direction
and created new colors by removing the magenta component.
Classic Chrome also controls the saturation and hue of reds
and greens to produce a unique chromatic balance.”

The original Velvia was an ISO 50 film. In practice, many photographers used
an exposure index (EI) of 40 or 32 to over-expose it slightly (one or two
thirds of a stop respectively) in order to yield less saturated colors and
more shadow detail. It was discontinued in 2005.
Velvia 50 was reintroduced, on the new film base, in 2007. The original
Velvia had been discontinued due to difficulties in obtaining some of the
raw materials needed to make the emulsion. ... 阅读全帖 |

同时，营养和童年智力发育关系很大。有的人生来智力很好，但是发育阶段营养拖后腿
，最后也就平常了。当然，生来智力一般，营养再好也是个猪头。去年一篇新英格兰医

越好。 这是有saturation的。但是穷人的孩子，就到不了这个saturation point.....
.换句话说就是under-developed。
所以长相和智力肯定有关系，原因就是幼年营养（说到底就是家境）同时制约了两者，
。只要家境小康，基本上孩子不会太吃亏。但并不是说很好的长相和智力肯定有关系，
因为各自都有各自成长过程中的saturation point,受制于很多因素。 |

bacteria in the animal's stomach digest grass.

发帖数: 380 | 47 回到4，50年前营养匮乏的中国，椰子油就和猪油一样，营养热量都更丰富，比玉米油
，橄榄油强；可现在这年代，真没人敢冒险吃饱和脂肪太高的油，没几个人营养不良，
都跑去吃含不饱和脂肪的油了，这就是号召吃橄榄油的原因了。谁好谁不好，是相对的
，不过一个是饱和脂肪的油(椰子油和猪油)，一个是不饱和脂肪的油(玉米油，橄榄油)
，根据自己的身体，自己选吧。
“Pure virgin coconut oil, containing no hydrogenation (the process of
adding hydrogen to make a liquid fat hard), contains 92% saturated fat --
the highest amount of saturated fat of any fat.” |

发现美国的科研机构还是很敬业的。
人家早就研究好了水在土壤表面的蒸发数量和其他因素的
关系并且建立了数学模型。有很多天气站收集这些数据并且
算出每天每小时参考蒸发量。我需要的就是作个累计就可以
知道土里还剩下多少水了。然后根据我的草的种类和草坪的
阳光覆盖情况做出调整。这个比我想象的科学多了，也容易
多了。太赞了。
数学公式：
# ETo = grass reference evapotranspiration (mm h-1)
# Δ = slope of saturation vapor pressure curve (kPa °C-1) at mean air
temperature (T)
# Rn = net radiation (MJ m-2 h-1)
# G = soil heat flux density (MJ m-2 h-1)
# γ = psychrometric constant ( kPa°C-1)
# Ta = mean hourly air temperature ( °C)
# U2 = wind speed at 2 me... 阅读全帖 |

引子：
听Itek DX说处理黑白有若干种方法，于是尝试从网上整理收集在此。
里面的例子都是从网上各处摘录，仅作为例子，本人不拥有任何版权。
主要来自于无忌一帖。
首先，打开一张彩色照片。
1。最简单的，将图片直接转换成灰度模式。
通过点选菜单Image（图像） --> Mode（模式） --> Grayscale（灰度）实现。
这种方式基本上就没有调节的余地，出来的照片一般比较灰而无趣，基本不用。
类似的方法可以尽可能保留原有色彩信息：同样的菜单下，先将模式转换为Lab
Color，再转换为Grayscale。不过在显示器上通过肉眼观察区别不是狠大。建议
最后保存为RGB模式。
2。降低图片色彩饱和度。
通过点选菜单Image（图像） --> Adjustments（调整） --> Desaturate（
饱和度，去色）实现。等价于Hue/Saturation里面把saturation设为－100。
同样可以先转换为Lab Color，调整之后再转换为RGB。
3。使用Calculations菜单命令。
通过点选菜单Image（图像） --> Calcu |

发帖数: 40617 | 50 为什么用LR里的calibration和PS里的LAB加饱和，这个道理很简单
你去做一下极限的情况就明白了
一张照片，你在LAB里加饱和加到极限（a，b通道 curve直线斜率非常大）
再回RGB
另外一张照片，你直接RGB里加个hue/saturation图层，然后master通道饱和加40
对比看看你就明白了
RGB文件上操作saturation最大的问题就是“烧掉”，也就是出现大量细节的丧失和
色斑
说到是否原片和最后片子差异大。这个都是个人喜欢。如果你曾经在同一场景
用canon数码和fuji RVP50或者kodak E100VS这样的反转一起拍摄过，你就知道
差别有多大了
我前面回Eon的也说过，我风光的调色比较大胆，喜欢Galen Rowell的风格
你可以去看看他的作品
http://www.mountainlight.com/
基本上在现在的风光摄影师里很难找到这么浓墨重彩的了，他自己的风格其实也
变化很大，在中国拍摄的系列都是比较“真实”的颜色，但是美国的片子
都是无比艳丽的。我曾经去过位于Bishop, CA的这个gallery，看过很多片子
的实际放大作品，艳丽 |
