Things You'll Need
Instructions
Buy one roll of color slide film. It doesn't need to be loaded into a camera, or exposed in any way. Since you will be cutting this film to fit your lens, larger is better.
Develop the roll of film. The slide film will come out black, which is perfect for infrared photography---visible light will be blocked, while infrared light will pass freely.
Cut a section from the exposed film large enough to completely cover the camera lens.
Mount the film in front of the camera lens. The method will depend on the type of camera and size of the lens. For example, you might tape the film to the front of the camera.
Glue the film onto the glass of an inexpensive UV/haze filter for a more professional look. Once the glue is dry, mount the new infrared filter to the lens.
