Only Truth Matters

1. Question

The questions that always stay in my mind:

1. How is time defined?
2. How is time measured?
3. What’s the origin of time?

2. Thoughts

How is time defined?

A measurement of motion and movement.

• If a system is unchanging, it is timeless

Why can’t time go backward?

• Due to second law of thermodynamics, in a isolated system, the entropy would only increase

How is time measured?

Female labour income rate

Income:

• Richest 10%: 52% income
• Poorest 50%: 8% income

Wealth:

1. Saving

Live below your means, look what you earn

Should I spend money on something? optimize the freedom money get rather than the money itself

New grads? save money for what you want

How much should spend?

Marriage? Different styles

Kids, how money works, how things work,

College, consider the growth of tuition and investment

与小泉讨论世界的问题。小泉提出问题就是男的太多，导致战争不可避免；母权社会没有阶级，不滥生，集体抚养。

1. Why

最近出掉了用了大半年的Fujifilm X-S10，主要原因是对画质不太满意，ISO一高画面显得很糊

购入了Nikon Z5，对画质很满意，但是直出颜色远不及富士，所以研究一下富士色彩

硬件上，富士采用的CFA是X-Trans排列，尼康是非常常见的Bayer排列，不过理论上通过合适的插值，得到的RGB图像应该是差不多的

软件上，富士有看家的胶片模拟，尼康的色彩预设一言难尽。

2. 胶片模拟

在用X-S10的时候，常用的也就几种模拟

1. Provia默认模式，没什么特点

2. Velvia鲜艳模式，拍摄风景时采用

3. Classic Chrom经典正片，街头摄影时使用

模仿的是Kodachrome反转片，颜色比较平淡，饱和度没那么高

4. Classic Neg经典负片，最喜欢的胶片模拟，色彩浓郁
