Where does energy go when we leave a space? Post Lucem explores the vibration and movement of light that flows and transforms, either compacting, changing color, multiplying and creating a visual spectacle. This short film uses the stop motion technique with long exposure photographs, using the light painting method, in which brushstrokes of light are created in the air that are captured by the camera. Light represents the energy left behind by bodies and how it transmutes over time. This is an allegory to life, since in this the only constant is change, and we just have to flow and enjoy it.
