这是我从网上抄来的。我瞎翻译一下。大家凑合看吧。





美国人“登月”的阿婆锣项目用的照相机


关于美国人“登月”的阿婆锣项目用的照相机
Hasselblad were the manufacturer of the camera that took all of the photos on the Apollo missions. Jan Lundberg was the Manager Of Space Projects at Hasselblad from 1966 to 1975 and responsible for the production and building of the Hasselblad 500 EL/70 cameras that were used on the Apollo Missions. He says 'Originally NASA made all the alterations themselves, then they presented what they had done to us and asked if we could do the same, to which we replied yes we can, and we can do it better. We proceeded to make the alterations that were accepted by NASA.' Protective plates were added to the case and film magazine.

美国人“登月”的阿婆锣项目的全部（all）照片（photo）都是用Hasselblad生产的Hasselblad 500 EL/70 型照相机拍摄的。1966到1975年，Jan Lundberg 是Hasselblad的空间项目经理，负责生产阿婆锣用的Hasselblad 500 EL/70 型照相机。他说开设时NASA做了一些改动，后来他们给我们看了他们的改动问我们是否可以做，我们回答说我们可以做得更好。NASA接受了我们的产品。机身和胶卷合加了保护板。


关于美国人“登月”的阿婆锣项目用的胶卷
H. J. P. Arnold is an astronomer and keen photographer, an expert on space and astrophotography and was the assistant to the Managing Director at Kodak during the Apollo years. He has authored many space photography books. He comments that the film that was supplied by Kodak for the missions was essentially the same as used here on Earth. it was ektachrome 64 ASA or ISO as it is called today. He has commented that you would expect to see some small dots on the films where a high velocity nuclear particle had hit the film, however no evidence of this whatsoever has come forward. The only thing that would protect the film from this damage would be a thick layer of lead around the camera casing, which according to Hasselblad was not used. Let's also remember that the films were changed whilst outside on the Moon's surface and not in a controlled environment.

H. J. P. Arnold 是一名天文学家和摄影爱好者，是空间摄影方面的专家。在阿婆锣项目的时候，他是柯达的Managing Director的助理。他还写过一些空间摄影的书。他说阿婆锣项目用的胶卷基本上（essentially）就是地球上用的胶卷，当年叫ektachrome 64 ASA现在叫ISO 。他还说由于高速粒子打击胶卷，预料可以期看到在胶卷留下一些小斑点，但是没有看到任何有过斑点的痕迹。唯一保护胶卷的是保护照相机的一层铅板，据Hasselblad（生产阿婆锣项目的照相机的厂家）说当时没有使用保护铅板。请大家都记住换胶卷是在月亮表面而不是在有控制环境的条件下进行的。

An important factor to take into consideration is the great variations in temperature that the film would have had to endure whilst on the lunar surface. The temperature during the Apollo missions were recorded as being between -180F in the shade to an incredible +200F in full Sunshine. How could the film emulsion have withstood such temperature differences? The astronauts can be seen to move between the shadows of the rocks and then into full sunlight in some shots. Surely the film would have perished under such conditions?

一个重要的因素是胶卷必须承受的月亮表面的巨大温差。在阿婆锣项目的时候，月亮表面的温度记录是阴处-180度华氏（-118度摄氏）到阳处+200度华氏（+９３度摄氏）。底片怎么可能在这种温差下保持正常呢？阿婆锣项目的宇航员也从石头的阴影处到阳处。胶卷在那种情况下肯定是要完蛋滴。
