About the product
- To enable slow shutter speeds to be used to record movement in subjects such as waterfalls, clouds, cars, etc.
- To decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background.
- To decrease the effective ISO of high speed film (ie: above ISO400) and allow it to be used outdoors in bright situations.
- To allow video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which would normally cause overexposure.
