"The astronauts were well trained before the mission in the use of photographic equipment. Since there were no weather effects to contend with and the bright sunlight scenes permitted the use of small apertures with consequent large depth of field, the equipment was generally kept at a single setting for the duration of the mission. All that was required of the astronauts was to open the shutter to take a picture. Film winding was accomplished with a motor drive.
In these conditions it is possible to take two photographs a second at best. The camera was in a bracket mounted on the front of their spacesuit, so they looked straight ahead at what they wanted to photograph; no viewfinder was needed. "
最快可以一秒钟拍两张。很多照片一看就知道是自动连拍的---拍的都是同一景物。
70-mm Hasselblad EL Data Camera. This electrically powered camera, carried on the lunar module, featured semiautomatic operation. It used 60-mm Biogon lens exclusively. The operating sequence was initiated by squeezing a trigger mounted on the camera handle.
