Infrared photographs are used by using special film that captures parts of the light spectrum that is not entirely visible to the human eye. Infrared photography is a combination of wavelengths that gives scientists a better understanding of whats happening on the Earth's surface. Infrared technology can be useful in assessing the health of plants because depending on what color their leaves are will reflect different shades of light. Unlike water that absorbs all the infrared wavelengths and appears black on film. Another helpful quality to these types of photographs are the ability to penetrate atmospheric haze. This therefore results in clear and crisp images of a particular areas suffering from haze. In general, infrared aerial photographs make it easier to collect accurate satellite images and high altitude aerial photographs.
