Why use a Variable ND Filter?
Neutral density filters reduce the amount of light going through the lens into your camera. By reducing the light you are able to achieve the following:
Allows the use of slow shutter speeds, with high speed films or digital cameras, to record movement/image blur in subjects such as waterfalls, clouds or any fast moving subject
Gives you full control over your depth of field. You are able to decrease depth of field by using wider apertures, which helps separate subjects from their background (subject matter in focus while your background is blurred)
Allows you to shoot high speed film (above ISO 400) in bright outdoor situations by reducing effective ISO
Enables cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which could cause overexposure
The Tiffen Variable ND filter operates on the same principle as a Circular Polarizer - rotate until you reach your desired effect and shoot. It allows you to have continuous control over the amount of light coming through your lens in an approximate range of 2 (ND 0.6) to 8 (ND 2.4) stops - while maintaining the integrity of your image. Note: The evenly spaced indexing marks between MIN and MAX do not represent calibrated stops. They are for reference only, to be used as a density bench-mark to return to a previous setting.
IMPORTANT: Only use your Variable ND within its recommended 2 to 8 stop range. If you go beyond the "MAX", you may experience an uneven exposure or color shift that appears as an "X bar" in the image.
