In our previous segment, we learned how to construct a pinhole camera.
In this segment, we will learn the working of a pinhole camera and how to capture images of non-luminous objects using one.
How to capture images of non-luminous objects?
The pinhole camera we looked at previously was constructed to capture the image of luminous objects, like the Sun. But for non-luminous objects like a distant tree or a pillar, we have to construct the pinhole camera in a different way.
The pinhole camera is now a rectangular box with a pinhole on one side and a translucent paper fixed as a screen on the other side, from where we will observe the image.

How does a pinhole camera work?
Suppose we are observing a distant tree with this pinhole camera. What we obtain on the screen is an inverted image of the tree.
