LPL started as a simple prototype. It had two buttons and was very slow. It was discovered by Joerg Miedza, a prominent member of the light-painting community. The app was very limited, but Joerg saw it as the next step in the evolution of light-painting. He wanted to know if it could be improved, so he emailed the developer. Ever since then, Josh and Joerg have been exchanging ideas and improving LPL.
Joerg Miedza: Artist
Joerg Miedza has been creating movies and photos using special techniques since the late 90's. He is the co-founder of the german light-art project LAPP-PRO. In this project, the LAPP-Team developed a unique brand of light painting: LightArt Performance Photography, or LAPP for short. The skills Joerg acquired working with motion pictures allowed him to contribute significantly to the performance and artistic aspect of LAPP photography.
