The Lee Filters Little Stopper is a long exposure filter that reduces the amount of light entering your lens by approximately six stops. This gives broad scope to create incredible images using slow shutter speeds or wide apertures.
Why use a Little Stopper?
At six stops, the Little Stopper is ideal for those low-light conditions at the beginning and end of the day (when the Big Stopper's ten stops may prove too much), allowing you to enjoy increased flexibility with exposure lengths.
In many shooting conditions, this means that detail and texture in areas of movement such as the sky and water would be reatined, while still conveying a sense of time passing
How to use the Little Stopper
1. Before fitting the Little Stopper, first compose your image.
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. For example, if your meter reading suggests an exposure of 1/125sec at f/11, with the Little Stopper fitted, your exposure becomes 1/2 seconds at f/11. If your meter reading suggests an exposure of two seconds at f/11, with the Little Stopper fitted, your exposure 2 minutes.
4. With the Little 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 Little 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 Little Stopper, remembering to keep the slot in the filter holder nearest the lens free for the Little Stopper.
Use of the Little 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 Little Stopper, or which white balance settings to apply. If shooting Raw, any colour cast can be corrected easily at the post production stage.
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.
