Near infrared, that is. It starts at 720 nanometers on the light spectrum, just beyond visible light. I talked about this in a prior post. Its dark secrets are many. How do you expose it, how do I focus the image, how do I process it, what kind of filter do I need (checkout YouTube for videos on both digital and film infrared)? And the list goes on. However, once you begin to learn about its idiosyncrasies, you start getting some pretty weird photographs. Which is what it is all about. Take a look, below.

First of all, you need a bright, sunny day because that is where all the infrared light is. It turns foliage white and blues black (look at the sky and water in the background). And it has high contrast. The affects can be surrealistic and or austere. Be prepared to bracket all your exposures and waste a lot of film when you first start shooting infrared.
You will find more of my most recent weird stuff in the first seven photographs, here.
