This is an infrared portrait (one of my first).

Infrared light it outside the visible light spectrum, and thus invisible to humans. However, digital camera sensors are sensitive to infrared light (varies by camera model and if the camera has been modified or not). A filter that blocks visible light, but allows infrared light to pass through, can be used to take photographs in the infrared spectrum. Infrared photographs are often referred to as "false color image" since the infrared light that reaches the sensor is ultimately viewed as visible light when the resulting photograph is viewed by a human (i.e. the color was previously infrared, but has now been mapped into something visible by humans).
