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。

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.

当发射光照到相机的传感器上时，每个像素点抓取一个特定的波长，并对匹配波长的光线进行电子放大。 从仅有几个光子的微弱的原始信号，放大到可见的强度。

That amplifies the original dim signal, composed of just a few photons, until it becomes visible.
