Infrared photo of girl with a bubble

Science Photography often takes place outside the light that is visible to the human eye. In this image the light is far infrared. Special cameras lenses are used involving bizarre materials like pure Germanium. The cameras resolution is regulated by the United States Military, but in recent years the standards have been relaxed and now 640x480 are fairly common. The camera only sees heat in a black and white picture. Since the human eye does not see this part of the optical spectrum any color can be assigned to any temperature. In this image blue is assigned to the cooler temperatures, while red is assigned to the hottest areas. Here a young girl blows a bubble with bubblegum. The air inside the bubble as well as the bubble itself cools off quite quickly.
