Chapter 3 - Camera Obscura

Adams is kept in a dark room as he recuperates from the measles. It must have been incredibly boring. He noticed a light from the top of his window produced a projection on the ceiling that showed the outside world. This is similar to a Camera Obscura. By allowing light through a small point into a darkened room, we can produce an image from the outside. The image is upside down. Ben tells me that is the same way our eyes work - with our helpful brain flipping the image over for us without even asking. With my understanding of how a Camera Obscura works, what Ben is telling me makes sense. So Ben, why is the image upside down in the first place?

This looks like a fun experiment so we are going to make a Camera Obscura in the best place to do so in our house - Ben's Bedroom.
