The LEE Filters SW150 Big Stopper filter has a delay of approx. 10 f.stop, our advice is to do some tests before using the filter to ensure correct exposure compensation.

Some instructions for using the Big Stopper filter:

  • First determine your composition before placing the Big Stopper filter in the holder.
  • Now measure the light without the Big Stopper in the holder and set the desired combination of aperture and shutter speed.
  • Multiply your exposure by a factor of 10, for example if your measurement is 1/250 sec at f11, with the Big Stopper filter your exposure time will be 4 sec. at f11, or if your meter shows for example 2 sec at f11, then with the Big Stopper filter that is already 32 minutes!
  • Now place the Big Stopper filter in the holder, it has a foam sealing edge at the back, the sides with less foam on the edge go into the filter slots and pay attention! the filter must always be placed in the first slot (closest to the front glass of the lens) of the filter holder with the foam edge facing the holder.
  • Always use the most solid tripod you have available for shooting long exposures, and be careful not to touch the tripod or camera during the exposure time.
  • Close the eyepiece of your camera so that no light can enter through the viewfinder, this prevents flare.

The Big Stopper filter can be used in combination with other filters, such as the Soft, Medium and Hard Grad filters. You must first place and position these filters before placing the Big Stopper filter, as indicated earlier, in the first slot (the closest to the front lens ).

The use of the Big Stopper filter can cause a blue color cast, the instruction booklet points this out to you, however, if you photograph in RAW then the color cast can easily be removed afterwards, another correction option is that you set the color temperature on your camera before shooting set it to a higher Kelvin value, that will remove much of the possible blue cast in advance.
