Lee Filters Seven 5 Little Stopper - S5LS
This is the Lee Little Stopper Neutral Density 6.0 Filter (75mm Glass) [S5LS]
The names of the long exposure filters have nothing to do with their physical size and everything to do with creative options. The Big Stopper & The Little Stopper are both available for the 100mm, SW150 and the Seven5 Systems. "Big" or "Little" refers to the light stopping power of each - not their size. The Big Stopper is a 10 stop filter. The Little Stopper is a 6 stop filter. These technical differences translate to a lot of flexibility for your creative photography
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 retained, while still conveying a sense of time passing.
How to use the Big or Little Stopper
First compose your image before fitting the Big or Little Stopper.
Take a meter reading without the filter in place, and set your desired aperture and shutter speed.
Use the exposure tables to find the correct exposure. Your filter will have come with a printed exposure table.
With the Big or Little 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.
Both the Big Stopper & Little Stopper can be used in conjunction
