But exposure times were much quicker by the 1880s, and the introduction of the Box Brownie and other portable cameras meant that, though slow by today's digital standards, the exposure was almost instantaneous.

但到了 19 世纪 80 年代，曝光时间已经快得多了，盒子布朗尼和其他便携式的问世意味着，尽管以今天的数字标准来看很慢，但曝光几乎是瞬时完成的。

Instead of looking at previously-known galaxies observed from ground-based telescopes, they pointed Hubble at a relatively empty part of the sky and took hundreds of long exposures over a 10-day period, then combined them.

他们没有观察从地面望远镜观察到的先前已知的星系，而是哈勃望远镜指向天对旷的部分，并在 10 天内进行了数百次长时间曝光，然后它们组合在一起。

Now, many of the beautiful shots of the night sky you've seen in this video are time lapses, made with long-exposure photos that show you a bit more than you can see with your own eyes.

现在，您在本视频看到的许多美丽的夜照片都是延时拍摄的，这些照片是用长时间曝光的照片拍摄的， 向您展示的比您亲眼看到的要多一些。

And so what happened was after the daguerreotype, Photographic processes continued to evolve to become easier to use, to become much faster exposure times.

于是， 达盖尔摄影法之后，摄影技术持续进化， 变得更加易于操作，曝光时间也大大缩短。

Even if that  level was a problem for our cameras, we can still see darker objects by utilising longer  exposure times.

即使这个水平对我们的来说是一个问题，我们仍然可以通过使用更长的曝光时间来看到较暗的物体。

So in order to study distant places in the universe, astronomers take long exposure images of the night sky.

因此，为了研究宇宙遥远的地方，天文学家拍摄了夜的长时间曝光图像。

The exposure takes some time, and it's influenced by the average intensity of this wave over that time.

曝光需要一些时间，而且它受到这段时间内这束光平均强度的影响。

The simplest explanation is exposure time.

最简单的解释是曝光时间。

At Vercel, we have one of our sort of internal operating principles as increasing exposure hours.

在维赛尔，我们有一个内部运营原则，那就是增加曝光时间。

Himself a pioneer of astrophotography, Barnard produced a series of stunning long exposure photographs of the Milky Way, which was published posthumously in 1927 as the Atlas of Selected Regions of the Milky Way.

作为天体摄影的先驱，巴纳德拍摄了一系列令人惊叹的银河系长时间曝光照片，这些作品在他去世后的1927年以《银河系选定区域图集》的式出版。
