The Lee 4 x 4" Big Stopper Filter is used when you need something to reduce your exposure by a whopping 10 stops. This powerful filter allows artistic "blurring" of images such as moving water, cars, sports and other subjects. The effect of this filter also permits slower shutter speeds as well as wider lens apertures.

The Big Stopper filter has a foam gasket on one side of the filter – this makes a tight seal when fitted into the first slot of the Lee Foundation Kit. It will fit any matte box that holds a 4x4” filter, but it may not make a light-tight seal, detracting from the final photo.

An adapter ring is required to fit the Lee foundation kit to your lens. You can even combine this filter with other Lee filters such as Graduated Neutral Densities to achieve additional special effects. The 4 x 4" format (100 x 100mm) is fantastic to use with a variety of different lenses.

As with all Lee Filters, The Big Stopper is made to exacting standards. It is best used for outdoor, nature and location photography.

Allows you to use a much slower shutter speed or wider lens aperture

This filter will permit you to "blur" moving objects such as water, rivers, cars, etc

Increased exposure times open up a whole new world of possibilities

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.

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.

Professional hints:

White balance

Use of the Big Stopper may result in a slight colour cast. It's worth conducting some tests to learn either which colour-correction filters to use in conjunction with the Big Stopper, or which white balance settings to apply. Or just shoot in raw and correct colour casting with post processing.

Reciprocity failure

When making long exposures, film users need to take reciprocity failure into account. Different brands and speeds of film respond differently to long exposures, so always refer to the manufacturers' recommendations first. To be completely sure, carry out tests with your chosen emulsions and bracket your exposures.
