The Big Stopper is a long exposure filter that increases the exposure time by 10 stops.

It'smade from high quality optical glass with foam edging on the reverse to ensure a light-tight seal. 100mm and SW150 sizes come in a protective tin and the Seven5 filter is in a handy storage sleeve.

By greatly extending exposure times the Big Stopper has the effect of allowing anything that is moving in your image to become blurred or ghost like, for example clouds, waterfalls, rivers, and the sea.

Used creativity The Big Stopper can change the way we look at moving objects and capture a real sense of time passing in your images.

How to Use a Big Stopper

  1. First compose your image before fitting the Stopper.

  2. Take a meter reading without the filter in place, and set your desired aperture and shutter speed.

  3. Use the exposure tables to find the correct exposure. Your filter will have come with a printed exposure table and there's also a free iOS or Android exposure app.

  4. With the 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.
