]]> 87087 2 0 Step Open webcam Using a screwdriver, unscrew and gently pry open your webcam’s plastic casing.

]]> 87088 3 0 Tip If you need to, take a digital photo of your open webcam to make it easier to reassemble later.

]]> 87089 4 0 Step Twist off lens Inside the webcam you’ll find a circular lens assembly attached to a circuit board. Unscrew the lens assembly from the board.

]]> 87090 5 0 Step Remove IR coating On the back of the lens assembly, you’ll see a small plastic or glass reddish square. That’s the infrared – or IR – coating, which blocks infrared light from entering the lens. Remove the IR coating by scratching it off with the tweezers. Be careful not to scratch the glass it’s covering.

]]> 87091 6 0 Step Cut negatives Take a strip of exposed color-photo negatives and find two squares that are completely black. Using the small square of glass from the webcam as a template, cut two pieces of negative, one from each square.

]]> 87092 7 0 Tip If you don’t have any color-photo negatives, you can make a filter using the film from inside an old floppy disk.

]]> 87093 8 0 Step Replace with negatives With tweezers, slide the two squares of photo negative on top of the piece of glass that you scraped, one on top of the other. These new filters will block out visible light, allowing only the infrared spectrum to enter the lens.

]]> 87094 9 0 Tip To avoid fingerprints, handle film negatives with latex gloves.

]]> 87095 10 0 Step Reconstruct webcam Reconstruct your webcam.

]]> 87096 11 0 Step Shoot infrared images Hook up your modified webcam to a computer and start experimenting with snapping photos and recording video in infrared. All visible light will be drained from your images, so shoot near a candle, incandescent, or fluorescent light, which all emit different levels of IR light.

]]> 87097 12 0 Fact Rattlesnakes have infrared receptors in their cheeks that allow them to sense the heat from their prey, helping them hunt in total darkness.
