That's why cameras use flashes in low-light environments: the flash gives the camera's sensors an extra dose of photons, the particles that make up light, Fergus says.
费格斯说，照相机在光线昏暗的情况下需要使用闪光灯的原因是：闪光给照相机传感器提供大量额外光子，光线正是由这种粒子组成的。

So let me offer a few tips about taking successful pictures when the light gets low.
下面我要谈论的是光线变暗时拍出好照片的技巧。
Night scenes which contain artificial light sources should almost always have low-key histograms, otherwise these will have significant blown highlights.
带有人工光的夜景几乎总有暗调子的情况(即low - key直方图)，否则就会出现明显的高光反差(blownhighlight)。
They move silhouetted against a land white as white, bathed in gentle light as the sun traces a low arc across the horizon.
当太阳低弧度越过地平线时，它们走动的身影映衬着一地的雪白，沐浴在柔和的日光中。
While you'll always be more comfortable reading in good light, there's no evidence low light causes any permanent harm.

ISO is a rough measure of sensitivity to low light.
ISO大致是在暗光下对光的敏感程度。
They'll also be able to take photos in low light conditions without using flash.
此外，该款相机即使在弱光条件下也无需使用闪光灯即可正常拍摄。
This means that in low light, when my pupils widen, I am seeing with the corrected zone and with a small uncorrected area.
这意味着当我们的瞳孔在微弱光线下放大时，实际上我在用已被矫正的瞳孔区域和一小部分未被矫正的区域看东西。
