Impossible Project has allowed me to revive Polaroid camera from my parents. The last photograph was taken in 1978. As everything is included in the cartridge (battery, reagents, photo paper), the device does not deteriorate with time. Only flat compared to the original cartridge: The time of "development" in the absence of light. 5mn, he spent 30 minutes with this modern process. Polaroid refused to disclose its development processes Impossible, which started from scratch. Let them time to improve. For me, it's like remade of photography on glass plate ... Use a device that belongs to the past. A real time travel!
