Infrared photography
Besides the colors that we can perceive, there is another kind of light that we normally cannot see, but can be made visible with a special filter on the lens of your digital camera: water and the blue sky turn black depicted, green tree leaves become white and the skin of persons becomes almost translucent white! So very spooky! The images that come out of the camera must first be post-processed for this effect.
