Fun fact. The word camera actually comes from "camera obscura", a dark room with a small hole in a wall that resulted in an image being projected on the opposite wall. This is of course just an oversized pinhole camera. Camera Obscura is Latin for dark chamber or room. So what we now call cameras is just referring to one of the older designs we have used to capture images.

BTW Wiktionary is my favorite dictionary/etymology website, though sometimes it's not 100% correct.

At Sutro Baths in San Francisco there's a large-scale camera obscura that you can visit where a view of the entire beach is cast onto a circular table that you can look at. There's no digital camera involved at all- just a large-scale application of an old school pinhole camera. It's amazing to see and definitely worth a visit!

Ibn al-Haytham invented the pinhole camera. He was an Arab scholar who studied the pinhole camera for the first time and used the camera to demonstrate how light can be used for the projection of an image onto a flat surface. When the size of the hole in a pinhole camera is made bigger, then the sharpness of the image obtained decreases. Also, the image becomes thick and blurry. This is because as the size of the hole increases, the amount of light entering the box increases disturbing the formation of the image.
