camera obscura

What did you see while you were inside the camera obscura?
i could see cars moving and buildings.
How is this camera obscura similar to the inside of a camera?
the pin hole is the same as the aperture.
Why was the image upside-down?
becuase as the image is going through a small hole it will turn it around making the image upside-down.
