Dark Retinex (Dartinex) allows you to see in very dark environments without using the flash! It reveals the objects in low brightness condition and recovers the natural color even you can't see with your naked eye.
Dark Retinex works best at low illuminance scene not completely darkness (nothing can see in total darkness!).
