老美阿波罗“登月”照相机，耳听为虚，眼见为实（图）
可惜啊，老美的阿波罗项目的设计者们在设计阿波罗项目时没想到月亮上的环境问题，他们以为地球上的高级照相机（Hasselblad 500 EL/70）和柯达胶卷就没问题了。结果呢，他们用登月的预算拍了一个电视连续剧。
后来，人们问问题了，人们问了月亮上的环境问题，比如说温度问题（The temperature during the Apollo missions were recorded as being between -180F in the shade to an incredible +200F in full Sunshine.），那啥就说用了各种涂料。
哈哈，耳听为虚，眼见为实！只是给相机涂涂料是不够滴，因为还有镜头！
看见镜头了吗？什么颜色？再看看下面这个图
镜头是什么颜色的？
老美阿波罗“登月”在月亮上用的就是这个照相机（图）
老美阿波罗“登月”项目在月亮上用的就是这个照相机，一模一样，没有任何修改，胶卷就是地球上老百姓用的普通柯达胶卷（ektachrome 64 ASA or ISO），本来要装一个挡板保护普通柯达胶卷防辐射（protective plates were added to the case and film magazine）或铅包装（a thick layer of lead around the camera casing），后来没装（which according to Hasselblad was not used.）
Cam on the Moon - Hasselblad 500 EL/70
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.
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.
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?
