PBS高端访谈:斯科特·凯利太空摄影（在线收听）

Hari Sreenivasan: When you're 240 miles from earth, the view is quite literally out of this world. Astronaut Scott Kelly spent 340 days on the international space station, setting an American record for the longest single space mission and while there, he also took photographs. Hundreds of them and compiled them into a book: Infinite Wonder: An Astronaut's Photographs From A Year In Space.

Scott Kelly: As an astronaut, photography is a really big part of your job because we take pictures for scientific reasons, we take pictures for engineering reasons and then we take photos to share with the public what we're doing in space. So you know it became part of my job and I you know became interested in it but really as a result of flying in space. I think the book has three sections it talks about the mission of flying in space and there's a section called the natural world which has pictures of the earth or space that you can kind of recognize what they are and then the last section is a section that we call Earth art, how you can take photos of the earth and really make it look like a wall worthy piece of artwork. My mother was an amateur artist and I think I got part of her artistic brain so I, over time, developed a technique where I could take a you know close up picture of the earth with a really long lens,

which is challenging when you're moving that five miles a second. So the camera has to move at a very fast but also steady rate to get an image that's in focus and then using a software program I would enhance the colors. I wouldn't add any colors but just enhanced them to you know bring out the natural colors.

You know it takes a long time to develop to get comfortable enough in space where you have you know steady enough hand to get the pictures and focus, especially when you take pictures at night and you use you know camera settings that are you know you're more likely to get is due to your you know your ability to track the earth's surface in a very steady and controlled way. I just saw how incredibly breathtakingly beautiful our planet Earth is. I knew right then and there I would never see anything like Earth again from space just, it's almost like someone took the most brilliant blue paint and just painted it on a mirror right in front of my eyes and it was absolutely spectacular.

哈里·斯瑞尼瓦桑：如果大家离地球240英里的话，看到的景象会完全不同。宇航员斯科特·凯利历时340天待在国际空间站，为美国创下了纪录——史上历时最长的太空任务。而且在空间站期间，他还拍了许多照片。照片有数百张，斯科特·凯利将这些照片编进了一本书里，名叫《无限奇迹：斯科特·凯利太空摄影》

斯科特·凯利：作为一名宇航员，摄影是工作中的重头戏，因为我们要为科学界拍摄照片，也要为工程学拍摄照片，此外还有部分原因是要与公众分享我们在太空中所做的事情。所以，大家应该能感觉到，摄影是我工作的一部分，而且我本人也对摄影很感兴趣，这是我从业后培养的一个爱好。我认为这本书分3个部分。第一部分讲的是在太空中执行任务的事情。第二部分讲的是自然界，这部分里面有地球和宇宙的许多照片，让人对地球和宇宙有一个认识。第三部分，也就是最后一个部分，讲的是地球艺术的话题，即如何给地球拍照片，而且要拍的很有艺术感。我母亲是一名业余艺术家，我觉得我遗传了母亲的部分艺术天赋。所以，随着时间的流逝，我培养了一个技能，即可以用长镜头给地球拍近照。这项工作很有挑战性，毕竟我要以每秒移动5英里的速度来拍摄。因此，镜头必须要以快速移动，但与此同时也要处于一个随时能聚焦并给地球拍照片的状态，也要随时能通过软件来加强色彩效果。我不会添加任何颜色，但我会加强色彩的效果，能呈现出自然色最好的状态。

大家可能知道，要花很长时间才能适应在太空的感觉。等适应之后，手才能稳定拍照并聚焦，尤其是夜晚拍照的时候，还要用到相机设置，这种情况下，如果手足够稳定，自己把控得住的话，就更有可能记录下地球表面的样子。我曾有幸见过地球令人窒息的美。从那一刻起，我就知道，太空里再也看不到像地球这样美的星体了，那种感觉就好像有人拿着最漂亮的蓝色涂料，在我眼前的镜子上画出了地球一样，真是美轮美奂。
