Made from high-quality optical glass, the Lee 100x100mm Big Stopper 10x Filter is a long-exposure ND filter designed to reduce the amount of light entering the lens by up to 10 stops. By greatly extending exposure times, it has the effect of allowing anything that is moving in your image to become blurred or ghost-like. The Big Stopper is compatible with the Lee 100mm Filter Holder (not included).

Why use a Big Stopper?

By greatly extending exposure times the Big Stopper blurs anything that is moving in your image, for example clouds, waterfalls, rivers, and the sea. The filter can also be used on cityscapes to blur people or on roads and motorways to blur traffic.

The Big Stopper is a high quality glass ten-stop long exposure filter. It reduces the amount of light entering your lens by 10 stops allowing you to use a much slower shutter speed or wider lens aperture.

The Big Stopper fits in the standard LEE 100mm Filter Holder allowing it to be used on a number of different lenses as well as in conjunction with other filters such as neutral density graduated filters.

The Big Stopper can be used in conjunction with other filters such as Neutral Density Graduated Filters. Other filters should be set up and positioned in the filter holder as normal before using the Big Stopper, remembering to keep the slot in the filter holder nearest the lens free for the Big Stopper.

How to use the Big Stopper

  1. Before fitting the Big Stopper, first compose your image.
  2. Take a meter reading without the filter in place, and set your desired aperture and shutter speed.
  3. Multiply your exposure by a factor of ten. For example, if your meter reading suggests an exposure of 1/125sec at f/11, with the Big Stopper fitted, your exposure becomes eight seconds at f/11. If your meter reading suggests an exposure of two seconds at f/11, with the Big Stopper fitted, your exposure becomes a whopping 32 minutes.
  4. With the Big Stopper inserted into the slot nearest the lens, attach the filter holder as usual and make your exposure.
  5. Always use the sturdiest tripod you can when making long exposures, and take care not to knock the camera or tripod. Cover your viewfinder before releasing the shutter to avoid light encroaching onto the sensor or film and causing flare.

Professional hints: Combining a Stopper with other filters

All the Stopper filters can be used in conjunction with other filters such as Neutral Density Graduated Filters. This gives an even greater level of control and creative possibilities.

Keep the Stopper closest to the lens

Other filters should be set up and positioned in the filter holder as normal before using the Stopper filter. Remember to keep the slot nearest the camera free for the Stopper. Ensure the foam seal is facing the backplate to prevent light getting behind the filter and causing flare.

What is the Lee system?

At the core of the LEE Filters system is the holder, which comes assembled with two filter slots but can easily be adapted to take up to four filters. The holder is designed to be compatible with 100mm filters – our standard width. To fit the holder to the lens, an adaptor ring is required.
