How does a pinhole camera work?
A pinhole camera works when a source of light travels through the aperture (front part of the camera) because of this it projects an image, which has been flipped around onto the other side. Pinhole cameras created inverted images because the light travels in a diagonal line through the air, therefore the top part of the image travels to the bottom of the pinhole camera and vice-versa. The term for this is the camera obscura effect. The placement of the pinhole camera changes how in and out of focus an object is.
