Who says people do not fly? Looking at these pictures, do not think so!
Three. If you are a photographer, then maybe you have ever taken photographs, which, in a happy coincidence, your object as if floating in air. But there is a special unit of photography, whose goal is to create the impression of levitation as much as possible quickly.
If the photographer will not move the camera during the repeated delays, it will be easy to separate the background (wall, floor, furniture, etc.) from a variety of objects exposed to "levitate."
But when it comes to floating objects, secret is the same - repeated delays that are placed on each other. Typically, objects are kept on the ropes hanging from the ceiling, or caught near the trees, and sometimes - on the ropes, protruding from the ground. Then the rope removed interfering with a computer.
Why don't you try the levitation photography? You can ask someone to jump up and hope for the best result. However, if you really want to see how to make these pictures better then search this topic on internet.
