many stops difference are there.
1. f/2.4, iso64, shutter 1/120

3. f/2.4, iso50, shutter 1/20
4. f/2.4, iso50, shutter 1/742
Between 3 and 4, I think it is about 5 1/3 stops.
I cannot figure out 1 and 2. Can someone take a look at this? |

Conspiracists devote much of their efforts to examining NASA photos.
They point to oddities in photographs and films purportedly taken on
the Moon. Photography experts (even those unrelated to NASA) answer
that the oddities are what one would expect from a real Moon landing,
and not what would happen with tweaked or studio imagery.
Conspiracists also argue that whistleblowers may have knowingly
tweaked photos in hope of uncovering NASA. Some of the main arguments

PEX is cross-linked polyethylene. Through one of several processes, links
between polyethylene molecules are formed to create bridges (thus the term "
cross-linked). This resulting material is more durable under temperature
extremes, chemical attack, and better resists creep deformation, making PEX
an excellent material for hot water and other applications.
How long has PEX been used?
PEX was developed in the 1960s. PEX tubing has been in use in many European

大家都知道，很多人不相信美国人的阿波罗“登月”，他们还找到了很多证据，这方面
的文章甚至网站都有不少，大家有兴趣有时间可以搜来看。为此，也就有很多为阿波罗
“登月”辩护的文章，维基百科就有一个长篇，链接：Moon_landing_conspiracy_
theories。
这里我只讨论维基的这个长篇里的一段，这一段是关于阿波罗使用的照相机的胶卷是否
能够在月亮上正常工作的。由于不像地球，月亮没有大气的保护，月亮表面的高低温的
差距和变化很大，具体地说就是差不多低温从-100到高温+100摄氏度的温差。
首先，我必须提醒大家一点，那就是这里提到月亮表面的从-100到高温+100摄氏度的温
差并不是说阿波罗使用的照相机的胶卷也达到了这样的温度，因为胶卷到了-50或+50摄
氏度恐怕就不能正常工作了。当然了，温度只是月亮表面恶劣环境的一部分，还有核辐
射也可以使胶卷曝光。
我只讨论这一段有两个原因，一个是我以前贴过一个叫《美国人“登月”的阿婆锣项目
