Pinhole photo using larger camera

This is a photo Geremy took of my today using the slide carousel carrying box that he'd previously used as a mini camera obscura (the "carousel obscura"). Today we did some tests with photographic paper, including colour paper, exposing it with this camera. Here is one black and white result. The colour result was rather mono-chromatic, partially because the paper was severely outdated and the chemistry mix was probably not optimal due to the mixing of a small portion. Some of you may surmise that the white halo which covers the middle of the image might be chemical stains or a light leak, but you would be denying the truth that this is proof that ghosts exist and are hanging out at the university.
