LAPP Pro

LAPP stands for Light Art Performance Photography and it's a project by Joerg Miedza and JanLeonardo Woellert. There is no photo manipulation involved in the creation of these images. They are created by the movement of luminous objects in front of a camera. They're basically the depiction of mini light performances.

May I add that my head is blown away by how awesome these images are. I tried doing something similar in the past but I never even got close to the sharpness, symmetry, and quality of these light drawings. 

There are more amazing images on the official LAPP Pro website.
