The Series-9 #25 Red Filter from Tiffen is a filter designed to build contrast in black and white photography and creates separation between the tones. Using this filter it creates dramatic skies or simulate a moonlit scene during the day by slightly underexposing the image and also eliminating fog and haze. Infrared film is enhanced with extreme contrast turning skies even more dramatic and turning foliage white in landscape photos. The filter has a filter factor of 8, so you must increase your exposure by 3 stops to compensate.

Tiffen filters are not dyed, but are manufactured by using ColorCore technology. This process laminates the filter material between two pieces of optical glass and grinds down and polishes the glass. The glass is then mounted to the metal ring, which after that can be screwed onto the lens for the desired effect.

A: The Tiffen XLE Advantix filter is designed for shooting extreme long exposures with still cameras to capture motion (waterfalls, streams, clouds, etc). This filter is not designed for video cameras. Here is the Tiffen product description:The Tiffen XLE Series ADVANTIX filter is designed to be used on DSLR cameras in B&W or Color mode, plus APS-C sensors in these modes when used in combination with lenses approved for IR photography. Designed to take extreme long exposure photographs in manual set up, the ADVANTIX filter will allow you to blur any movement in your image. The intensity of this effect is achieved through adjustments in manual mode of aperture, shutter and ISO settings. Designed to remove the near IR polluting light waves, the ADVANTIX removes these polluting light waves by introducing an active absorbing element. This element adds a slight greenish color cast to the filter, which can be adjusted for, either in your cameras white balance settings or in your post software afterwards. If shooting stills, the reddish cast in your image can be fixed by adjusting the still cameras white balance or in post with Lightroom.
