What happens to the image produced by a pinhole camera?

Explanation: If the back wall of the pinhole camera is moved closer to the pin hole, the light rays passing through the pin hole will be catches on the film at a shorter distance as compared to the original distance. Therefore we observe an image of small size with high intensity than the initial image.
