With the filter in place 99% of the light seen by the naked eye is blocked out and only infrared light is filtered through. Technically the naked eye cannot see 100% black but with the infrared filter and your camcorder specialist functions, you will magically be able to.Due to the nature of infrared photography, the filter factor for this filter is highly variable and depends largely on the ISO sensitivity in use and lighting conditions.
