      • 家园 自己看看去吧。。

        http://en.wikipedia.org/wiki/Examination_of_Apollo_Moon_photographs

        更何况LRO那么多照片都在

        想要拍的清晰 小光圈+别太慢的快门+稍高宽容度的胶卷就好

        • 家园 我把阿婆骡拍了那么些照片的解释拷过来了,你自己看可信不吧

          High number of photographs[edit]

          When the total number of official photographs taken during the EVAs of all Apollo missions is divided by the total amount of time accumulated by all of the EVAs, one arrives at a figure of 1.19 photos per minute. That is one photo per 50 seconds. Discounting time spent on other activities results in one photo per 15 seconds for Apollo 11. This is even more remarkable considering that many locations in the photographs are situated miles apart and would have taken considerable travel time, especially in bulky pressure suits. On top of this, the cameras were neither equipped with a viewfinder nor with automatic exposure control, which means that taking good pictures would take considerably longer.[31]

          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. Also, many of the photographs were stereoscopic pairs or sets of panoramic images, taken immediately after each other. The Lunar and Planetary Institute's Apollo Image Atlas shows that 70 mm magazine 40/S of Apollo 11 has 123 photos taken during the walk on the surface—less than one per minute.[32] In addition, by looking at the photographs in sequence, one can see that very often several of them were taken in rapid succession. Here is a list of Apollo 11 surface photos (AS11-40-5850 to AS11-40-5970). As can be seen from the map, many photos were taken from a similar position.

      • 家园 又在表演无知了,很多相片是用带自动控制装置的相机拍摄的

        就用维基百科给你扫盲就够了:

        http://zh.wikipedia.org/wiki/%E9%98%BF%E6%B3%A2%E7%BD%978%E5%8F%B7

        “洛威尔继续描述他们所飞越的月球表面。阿波罗8号的主要任务之一就是勘查计划中的登月点,尤其是阿波罗11号的计划登月点静海。阿波罗8号的发射时间的选择考虑到了到达静海时的阳光情况。专门有一部摄像机被安置在一扇窗前,以1帧/秒的速度拍摄月球表面。由于阿波罗8号未携带登月舱,登月舱驾驶员安德斯的主要任务就是拍摄尽可能多有价值的照片。任务结束时,三位宇航员总共拍摄了七百张月球照片以及一百五十张地球照片。”

        你以为所有照片都是人手拍的?可笑。

        • 家园 你自打耳光有瘾啊!又在表演无知了的是你

          海纸,你分不清哪个是人拍的,那个是机器拍的,如果你等月就把两种照片混在一起

          NASA可不是你这么无知这么傻,阿婆骡照片都是有编号滴,鱼行园拍的编号明示

          • 家园 NASA当然不是你这么无知这么傻

            第一:你把证据摆出来,NASA公布的几千张照片都是宇航员手工拍的?有什么官方说明?就靠你那一张嘴算什么?

            第二:带自动控制装置的相机也是由宇航员来操作的,把镜头对准开启就行。阿波罗8号那个就是如此。
