Well, from technology used to color film from the past, here's an idea of how NASA is using tech to get extremely high definition views of the international space station.

从过去用彩色胶片的技术来看，这里有一个关于 NASA 如何利用技术获得国际空间站极高的清晰度视图的想法。

Like I would have two Pentax K1000s or two Cannon AE1s, whichever one, I would put black and white film in one, color film in another, so I can compare the shots.

就像我有两台宾得 k1000 或者两台佳能 AE1s，不管是哪一种，我都会把黑白胶片放在一种，彩色胶片放在另一种，这样我就可以比较镜头。

With the arrival of color films, Butler realized he could put a subject in front of a specific color, then remove that exact color to isolate a subject from its background.

随着彩色胶片的出现，巴特勒意识到他可以将一个对象放在特定颜色的前面， 然后移除该颜色以将对象与其背景隔离开来。
