All digital cameras have a built-in infrared lens-blocking filter. This filter prevents infrared light from entering the sensor of your camera. Removing the infrared lens filter will enable your camera to see only the infrared spectrum of light. This makes for interesting and artistic photos.

Disassemble the webcam or digital camera using a Phillips screwdriver. Some cameras may have to be opened by prying them with a prying tool like a flat tip screwdriver.
Find the CCD (charged couple device) for the camera. This is the sensor that is behind the lens and is the part responsible for sensing the light on your camera. The infrared filter will be attached to the CCD.
Detach the infrared lens-blocking filter. It is a piece of glass that has a red tint to it. Some IR lens filters are square in shape while others are round. They can be removed using your fingernails or with the use of a flat head screwdriver. Remove the filter gently so as not to damage the camera assembly.
Attach the infrared band pass filter (the film negative) to the place where the infrared lens-blocking filter used to be. Secure the attachment using non-toxic craft glue or its equivalent. Make sure the glue does not go onto the lens or on any part through which light passes. Wait for the glue to dry.
Reassemble the camera.
