Why is the image inside the camera obscura upside down?

• light travels in a straight line, passes through the lens and is reflected onto the white paper in the back of the box

• they took the picture while the camera was upside down

• light travels in a zig-zag line, passes through the lens and is reflected onto the white paper paper upside down

Why don't we see everything upside down?

• because everything is already upside down and it just looks right side up

• because we are standing up right, not upside down

• Our brain automatically flips the upside down images reflected into our eyes
