When shooting with black and white infrared, the film must be kept in total darkness from the time when you take the film cassette out of the container, through the process of loading and unloading your camera, and until you are finished developing the film. This means carrying a portable darkroom around with you, but the result is worth the trouble. There is nothing quite like the look.

A red filter is always recommended on the lens to enhance the film's characteristics and eliminate ultraviolet light. There is also a focus shift adjustment because the wave length of infared light is different than white light. Most lenses have a red dot next to the focusing mark indicating the proper infared focus point. The shutter apperature and light meter are not affected by this infared Kodak film. Remember the red filter absorbs two stops fo light if you are using a hand meter. You must really test what ISO (ASA) that works best for you. Try ISO 100 to start.
