Yes. It's like looking through a straw. The opening closest to
you does, in fact, see 180 degrees. But most of what it is
seeing ends up being the inside of a tube, which is often devoid
of texture and contrast, and being opaque, doesn't render
photographically. This vs. the non-tube world, which comes
through the aperture on the other end, which is probably what you
want to emphasize. :)
