- Before fitting the Big Stopper, first compose your image.
- Take a meter reading without the filter in place, and set your desired aperture and shutter speed.
- 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.
- With the Big Stopper inserted into the slot nearest the lens, attach the filter holder as usual and make your exposure.
- 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.
