Infrared night-vision

Lions are nocturnal predators; trying to photograph them without disturbing them and their prey is a challenge. So you want to be able to photograph the lions without disrupting their natural behavior, and that means switching to thermal and infrared photography. We’ve modified normal digital cameras to shoot infrared. If you remove the anti-aliasing and infrared filters that are standard on every digital camera sensor, you have a camera that’s capable of gathering a broader spectrum of light than is possible to see with the human eye. Camera manufacturers constrain sensors to capture only visible light. We modify and replace the daylight-bias filtering with an infrared filter so that the camera captures only the infrared spectrum. That camera, coupled with strobes or spotlights filtered for infrared, allows you to photograph in the dark without disturbing the natural behavior of the animals.
