对于较冷的光源（蓝或绿色），你会让相机给照片增加暖色，而在暖光源下，你要让它给照片降温。

For cooler (blue or green) light, you'll tell the camera to warm things up, and in warm light, you'll tell it to cool down.

相对于传统光源，这些新型的光源有很大的优势。 “LED和OLED是有史以来能源效率最高的光源。”

Together, these light sources offer huge advantages over conventional lighting.

这种电池可以利用许多令人惊奇的光源，他表示，包括某些最微弱的光源。

The cells draw on many surprising sourcesof light, he said, including some that offer the barest trickle.

OK, so we've got UV light here, and let's see what we can see, and we lose electrons, if that's what's happening.

好了，我们已经有了紫外光源，让我们来看看能观察到什么，如果那些事情发生了，我们将会失去电子。

So that means we're going to need to figure out what is the energy per photon that's emitted by that UV light.

所以那意味着我们将需要,计算出从紫外光源发射出的,每个光子的能量。

It'll still likely get stuck in that spot, but we'll just show you one more time the effects of the UV light, and actually we'll throw in an extra trick here, too.

它仍然像是在那点卡住了，但是我们还是会再展示一次,紫外光源的效应，事实上，我们也会引入一个新的技巧。
