There are many ways to force the perspective of a photograph. Some are more difficult than others and require better cameras and more knowledge. But the ones we present here don't need much trickery: just with imagination (and any little camera) you can achieve unique and original photos. We're talking about those photos where the world turns upside down, people fall from bottom to top, that twist space just with a different camera placement (and quite uncomfortable poses, of course). The photos are easy to understand, although many cause vertigo, so we won't dwell on explanations. Enjoy them!
