Another way to safely view the eclipse is to use a pinhole viewer.

另一种安全观看日食方法是使用针孔观察器。

Pinhole bored dwellings suggest that our sulfuria grows in them more abundantly than might be expected.

Now your pinhole projector is ready, so you can head outside, make sure the sun is behind you, hold the projector up to your eye, and then look for sunlight to come into the projector.

现在你针孔投影仪已经准备好了，这样你就可以出去观测了，确保太阳在你背后，将投影仪放在眼睛前，然后等待阳光进入投影仪。

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，投映到光线较暗室内幕布上。(新研究明，这种技术可能是代尔夫特耶稣会士介绍给他)。
