Huh? I can't get my head around the logistics of this. If it were on the lens it wouldn't be in focus and perhaps not even visible depending on the lens. But if it were walking in the film, you would just see an outline of the bug right? But we see it from the top, with a light source and everything. Even if it were somehow exposed properly, we would see the bottom and not the top? So it's probably on some internal piece of the camera? And perhaps really really small, but looks larger because it's close to the film?
Can someone with knowledge of the internals of this specific camera enlighten me as to how this works?
