Burncycle, the author of the article obviously presented a collage of individual photos to make everything more visible.
For instance on The Day Hunter photo, he has photographed a collection of individual photos. True, they are not to scale of each other, but they are clearly visible. For instance, the safety pin is almost as long as the signal mirror. Obviously not true in actuality but enlarged here for your viewing.

I'm not sure I made any sense in what I said. However, I know what I meant. <img src="/images/graemlins/grin.gif" alt="" />
