The big question is: Did he use a Camera Obscura, an optical device to paint this?

他画这幅画是否用了暗箱这种光学装置？

His room likely acted as a camera obscura just like this one.

他的房间可能就像这个暗箱一样。

In West Hollywood, California, a group launched an American version of the event on January 11, 2014, reported Atlas Obscura.

据《Atlas Obscura》报道，2014年1月11日，加州西好莱坞的一家公司提出了一种美式的购物节日。

This is the inside of a bouncy castle and we turned it into a camera obscura.

这是充气城堡的内部，我们把它变成了暗箱。

So remember, one thing he noticed about the camera obscura is that images from out here in the outside world are flipped upside down.

所以请记住，他注意到关于暗箱的一个现象是来自外界的图像被颠倒过来。

In a camera obscura the image projected from the outside world is flipped upside down, which must have looked pretty strange to somebody 1,000 years ago.

在暗箱里，从外部世界投射的图像被颠倒过来，这对 1000 年前的人来说一定很奇怪。

A camera obscura is basically just a dark room with a tiny hole at one end that lets an image of the outside be projected onto this back wall.

暗箱基本上就是一个黑暗的房间，一端有一个小孔，可以将外面的图像投射到后面的墙上。

He found a way to fix images by dipping paper into photosensitive chemicals and exposing it to light inside a camera obscura, which is essentially a dark room with a tiny hole in it.

他找到了一种修复图像的方法，将纸浸入感光化学物质中，然后将其暴露在暗箱内的光线下，暗箱本质上是一个暗室，里面有一个小洞。

He was probably familiar with the camera obscura, a device that projected an image through a pinhole and onto a screen in a darkened chamber (new research suggests he may have been introduced to it by the Jesuits of Delft).

维米尔可能对暗箱技术很熟悉，这种装置可以让图像透过小孔，投映到光线较暗的室内幕布上。(新的研究表明，这种技术可能是代尔夫特的耶稣会士介绍给他的)。
