Tiffen IR Filter #87 for 67mm lens - $30 (Las Cruces)

Get creative with this filter on a film camera using Infrared film to block all visible light. The dark filter allows only the infrared energy to reach the film. Filter can also be used on digital cameras, however adjustments to the camera sensor are required. Filter comes in a case, but the snap holding the case closed is broken. I use a sturdy rubber band to secure the filter. (see photos.)
