These photos will make you think twice about what you've just seen. Is it just the trick of a camera or is there really a man on a cloud, you'll wonder. It's actually called forced perspective photography, where objects are moved around to make them appear larger or smaller, depending on the image being portrayed.

Some call it an optical illusion, like when you see a picture of someone grabbing the moon out of the sky. Highly impossible but amazingly creative! Travelling offers some of the best opportunities for these types of photos which sometimes require more space.

Anyway, if you can't get close enough to kiss the Mona Lisa, why not just pretend like you did in a photo. Check out all this cool pics and see who kissed The Great Sphinx of Giza and who picked up the Eiffel Tower.
